Do any of you know the best way to build a high reliability e-mail system?
I currently have Interworx as the default Control panel but are happy to change to Cpanel or otherwise. The iworx HA is not that good as if the cluster manager fails you loose everything.
I guess my only option is to do what most companies do and hope for the best - but have a good disaster recovery plan.
Is there any conventional wisdom on WHT about which shared hosting providers have highly reliable email service?
The provider I have now has very good web hosting service but their email services tend to bitbucket far too much mail for comfort. Reliable delivery and reception for the half a dozen emails I might send/receive a day (it's a personal use site) is I hope not too much to ask without needing to pay and arm and a leg for the privilege.
is it really worth the money nowadays to put in SCSI or SAS instead of SATAII (single disk, non-raid here), IF reliability is the only concern (i.e. NOT i/o performance) during the usual 3 year life time of a server?
Actually, I was pretty amazed by the sata reliability, in the past 3 years the only hdd failure was two sata on a mismatched mobo, which didn't support SATAII (a lot of read/write error, eventually died). Although we have 0% scsi and sas failure.
to colocate a 1U in the DC metro area for $100/month for a small non-profit I work with. The service necessary is pretty basic -- 1Mbps or so would do (preferably unmetered so we're not on the hook for overage charges), 1 or 2 IPs would be fine, and the only real service necessary (besides steady power and connectivity, of course) would be the occasional remote reboot and 24/7 facility access.
I've come close to settling on Crosslink Internet (web site at www dot crosslink net, silly system won't let me post the URL directly because I'm new), because they're the only place I've found that can meet that price point. Before I commit, though, I wanted to hear from you guys:
* Are they a reliable ISP? They sound sort of low-budget over the phone, and while that's not necessarily a valid indicator of reliability, it makes me nervous.
* Are there any other decent ISPs in the Northern VA vicinity that could meet this price point that you guys would suggest over Crosslink?
I currently have a Signature VPS with Servint and although I have found their customer service good and am getting concerned about my VPS's reliability. This is the only VPS I have experience with.
At the beginning of the year I was experiencing downtime at least once every couple of weeks and for at least 20 mins each time. Sometimes my VPS was down for over an hour. Most of the time the explanantion I received was a "Kernal Panic". Then for the last month and a half things have been good with no downtime, until today when my VPS went down again for about 50 mins.
So here I am asking what is normal downtime?
Is the downtime I am experiencing the norm and would I get the same reliability from any provider?
Would a dedicated server tend to be more reliable than a VPS?
I am considering moving to a dedicated server at LiquidWeb, not because I need the resources but I am wondering if reliability would improve. I am willing to pay for reliability! Any advice as to whether this would be a good move?
I would really like to know which hard drive brand you have had the best success with in regards to server hard drive reliability. Is it Seagate or Western Digital? Or is it one of the other brands? Please vote. This poll is specifically regarding SATA2 hard drive experiences in servers. Please do not factor in SCSI hard drives.
View 14 Replies View RelatedIn order to increase the reliability of a audio streaming service I am thinking to take the action I describe below.
1. Buy two Windows VPSs with WMS installed.
2. Register a domain name (i.e audiostream.com) with 4 nameservers: ns1.ip1_vps1, ns2.ip2_vps1, ns3.ip1_vps2, ns4.ip2_vps2.
3. Create all publishing points (streams) on both servers.
Normaly VPS1 should serve all clients. In case VPS1 goes down, VPS2 should jump in and serve all clients-connections. As soon as VPS1 becomes available (ns1 & ns2 start responding again), VPS1 starts serving all new connections.
Load balancing or any other kind of advanced load, traffic, etc management is not important.
Then we have the following cases:
1. VPS1 is down , which means that VPS2 should take charge.
2. VPS1 is up (ns, http, ftp services), but WMS1 is down (crashed). Means that the playlist (asx) file should be built so that it also includes the IP, port & publishing points of VPS2. This should be done because ns1 & ns2 will answer without any problem, but WMS1 will be crashed and won't serve any media connections, thus ASX will look for the next available stream in the playlist.
Do you think that the above is possible. Is this gonna work?
Requires a dedicated server in Europe.
Requirements:
1) Processor: Intel Core 2 Duo 2,2 GHz;
2) RAM: 2024 MB DDRAM;
3) Hard Drive: 2x 250 GB SATA (can be smaller);
4) Traffic: At least 1000 GB or unrestricted;
5) Port: 100 Mbit / sec. (ideally 1000 Mbit / sec.);
6) IP-Addresses: 2.
Mandatory conditions:
1) A great date-center;
2) Operational and anglophone support;
3) Ability to establish a panel, for example: ISPmanager.
Recommended requirements:
1) Protection against DDoS-attacks;
2) The ability to administer the server, a company that provides services to lease (regular updates, round-the-clock monitoring, etc.).
The server is designed for the site, which will:
1) Forum;
2) Video and audio materials (up to 20 spots, for up to 10 minutes each), which can be viewed directly on the site using flash-player or download. Clips will not be frequently changed or supplemented;
3) Downloading developed software, up to 0.5 Mb;
4) Download documentation formats: DOC and PDF, up to 2 Mb;
All audio, video and documentation for its own production.
Additional information:
The number of visitors, initially to 10000 per month (probably much less or slightly more, not yet known) The audience will be visitors from the following countries: Ukraine, Russia, Poland, UK, Germany, France, USA and Canada.
Budget:
up to $ 200 a month. But if such amount is not sufficient for the entry requirements, are ready to revise the budget.
Need a really high-quality channel of communication and operational support, etc. Perhaps for these tasks, you recommend other requirements to a server and placing the territory? Check your real council.
Also look in the direction of affordable rental server and utilization of services: Akamai Technologies. If someone has experience working with Akamai, I ask, share their views. Should I use it for such a project?
A lot of information has been revised to servers in Germany, UK and USA. But the single answer, yet to be found.
I'm completely torn on going the absolute budget route vs spending more for something that'll allow easy upgradeability in the future. I basically need lots of space but file sending-- media like mp3s, video, etc.
it'll be raid 5 and I'll need at least 2-3TB initially but the ability to expand would be nice.
option 1:
nice chassis with plenty of hotswap bays with sas expanders
expensive sas raid card
option 2:
cheap chassis to serve "immediate" needs and go with more later.
not sure what I'd use as a card? maybe even onboard?
regarding reliability: I once saw a database of failure rates of different models. raptor was the most reliable of the "desktop" drives. anyone have the link? I'm wondering of the seagate ES drives are worth the extra money vs the non-ES drives. they're supposedely more reliable and the "server versions" of sata drives.
I'm having difficulty sending an email to another email address (with a different domain) which is on the same VPS.The trouble is, on the other domain's VPS control panel, within the DNS settings, the MX records have been pointed externally (to an exchange server). Their email is turned off. But bizarrely, their mailbox is full.
It seems as though Plesk is ignoring the MX records, and sending MY email internally to the OTHER domain's mailbox on the same VPS.How do I get Plesk to send my mail to the correct EXTERNAL MX records?
I had a email address I deleted on my server (postfix on Debian 4), but to my surprise the server still recieves email for the address!
(I have manually tried sending a email to the address and it comes througt).
I have deleted the address from the /etc/postfix/virtual file and restarted postfix.
What could I have forgotten?
One of my customers asked me if is possible technically to offer free email services.
Since he's going to launch a big portal he want to offer such things later, for all users.
Now, there are problems as:
a) if there is any possibility to compress emails similar with GMAIL or YahooMail or so, because i can't imagine the email is uncompressed
b) how can be handled email boxes over multiple (mail ?) servers if the HDD space needed would be larger than for one server HDD ?
I am having an email issue and I can not resolve. I am hoping for some assisstance here.
One of my local clients are not able to email each other in their office. (About 10 employess I believe)
They are using Outlook mail client, and using ISP's SMTP server. They are able to send/recieve email to other users externally, but not intenally.
Using webmail works perfectly fine.
I spoke with my host and the said everything is working fine. I checked with the ISP to see if they are blocking the IP address on the SMTP server. They said they were not.
I have a personal account on the same server and tried to send email to another local email account, and it did not work either. Tried to send email to my clients email and they did not recieve anything.
I am on the same ISP as my client, so Im still not sure if its the ISP or not.
I setup mail piping with Exim so that e-mails sent to a specific account be forwarded to my PHP script. It's not working properly, because when I send a mail to this account, it's bounced by the mailer daemon:
Code:
This message was created automatically by mail delivery software.
A message that you sent could not be delivered to one or more of its
recipients. This is a permanent error. The following address(es) failed:
pipe to |/home/user/public_html/support/parse.php
generated by support@mydomain.com
local delivery failed
In my /etc/valiases/domain.com file I have:
Code:
support@mydomain.com: "|/home/user/public_html/support/parse.php"
*: :blackhole:
What can be causing the error?
On one my servers, I'm receiving hundreds of spam emails that are clogging up the email queue to email addresses that do not exist.
For instance domain.com, I would get
bob@domain.com
liz@domain.com
325235@domain.com
You get the picture. How do I setup my server so that if there isn't an email address setup the email automatically gets deleted instead of trying to attempt to deliver it?
I have a client who has his own hosting account, and wants to leave his e-mail on his own hosting account, but his website on my hosting account.
On his own hosting he has created a sub domain called shop, and pointed its A record to the IP address of my server. On my server I've setup his domain name, and created the sub domain shop. That all works fine.
The problem I have is that the site under the shop domain needs to send an e-mail to sales@hisdomain.com. Now my server thinks the main domain is setup on my server, so it sends the e-mail to itself.
I'm justing wondering how I can get the server to point the mails back to his hosting?
A previous host I've used said they had to add the domain as a remote domain on the server, then they had to make some changes to /etc/localdomains because I was getting errors trying to send mails to the address.
A email account can send email, but cannot receive email, why? How do I know the answer why?
View 14 Replies View RelatedI currently have a domain on Server 1 (Linux, Apache, Ubuntu, Matrix control panel).
This server does not have any spam filter, so I have moved all the email accounts to Server 2 (Linux, Apache, Fedora Core, Plesk) which does have a brilliant spam filter; and have changed the DNS record for mail.domain.com to the IP address for Server 2.
Emails are being successfully received on Server 2.
On Server 1, when an email is sent through SMTP to an address at that domain, it does not send it to Server 2, it gets delivered to the hosting account for the domain on Server 1. So what I am guessing is happening is that Server 1 detects the domain has an account on the server, and instead of looking up the DNS info for that domain, just assumes it is on Server 1.
What I need to do, is force Server 1 to send email for that domain to Server 2. Is this possible, and if so, how can it be achieved? If more info about the server is required for a solution please let me know and I'll provide what I can.
I have a Windoze box with three ip addresses and running Mailenable Professional as the mail server software. I do not run any DNS, rather I set up the domain to point to my server at the registrar. All of a sudden I'm getting returned mail, "This server requires PTR for unauthenticated connections". When I run the diagnostics on the mail server it says that none of my ip addresses have reverse dns....... I'm confused, what do I need to do at the registar and server level to feel joy again?
View 3 Replies View RelatedI've searched around on the forums and it's really confusing to choose a host. I was wondering if you could pls recommend me a host...
The system will have about 20 users and each user should have about 4-500mb space for email. FTP will be used fairly often too with file sizes up to a few hundred mb. The website won't take up much space.
i have a client that has configurated his email in Windows/Outlook and it works perfectly..
the problem is that, when he configurates it from a Mac, he can recieve emails but he cant send..
its the same internet connection..
My question... Is there anything else that he has to configurate in Mac that he doesnt in windows?
What is more recomended. Using a hosted service such as Google Apps or using the VPS server for email?

For sure, this is no spamming, but I know that some companies out there are sensitive to a lot of emails. Therefore I am looking for a company who will talk to me first if they have any concerns and who will not suspend my account the rambo way ;-)
We have been using ************ for about 6months now and have had an ok experience on their windows servers.. But recently we have been getting delayed emails, coming in between 5 minutes to 10 hours after an order has been submitted. We have submitted several help tickets. They say what email is having trouble and its all of them, they say we will check on it and then nothing, its sporatic but sometimes its totally unacceptable.
View 4 Replies View RelatedPROBLEM: Emails sent via BCC end up with the TO: field empty and some servers reject the emails if the TO: field is empty."
Hi folks, I recently moved from a certain provider who had raised their rates twice in one year (and some of you know who I'm talking about). I moved to another provider for my dedicated server, but now have a problem with email I send from my forum. I run a discussion forum and sometimes need to send notices to my members. I use an admin "control panel" in the forum software (similar to THIS forum). I send the emails out via BCC, but there is a place to put a default address, such as "members@myforum.com" . With my previous server, when I would send those out via BCC and the received emails would have the default address in the TO: field. However, since moving to the new server, the emails no longer have the default address and instead the TO: field is blank when people receive the emails. The problem is, some people
s servers require someting in the TO: field or they reject the email.
Assuming this is a server problem (mail server configuration?) does nayone have any ideas what the propblem might be? I'm using the exact same software as I used on the old server where things worked properly.
