DNS Setup And Email Deliverability
Feb 28, 2008
I have a dedicated linux server that has 16 IP addresses... and one of those IP address is the main (or shared) IP of the server. So I can host a ton of websites on that one shared IP, and can optionally move individual accounts to one of the 15 other dedicated IP's if I so desire.
I put an account on it's own dedicated IP and it works fine. But I've noticed all my email being sent out is being filtered into people's spam folders... be it hotmail, gmail, yahoo, outlook, etc. My DNS is setup great as far as I can tell (DNSreport confirms) and I have SPF/domainkeys installed for this one account... so I shouldn't have problems authenticating my emails.
The only thing I can think of that would be causing problems for my mail being filtered as spam, is that since this account is on one of my dedicated IP's... that these mail providers (yahoo, etc) are looking at the incoming connection claiming to be the host, which is the main (or shared) IP of the server, and then looking at the MX record for the domain that the email address is, which points to that dedicated IP... and since they don't match... the email provider rejects the email cause the two IP's aren't matching.
Is this a valid assumption? And if so, is there anything I can do about it besides moving that one account back to the shared IP? For the life of me I can't figure this out.

Which type of email sending has a greater degree of deliverability.
1. PhpMail Function
2. SendMail
3. SMTP with or without authentication
I do not understand the differences between these.

Its been a while since I have posted on here, anyway heres my problem.
I have a cPanel server in my office which handles the email for 2 domains.
I've also got a reseller account on a helm server.
What I want to do is: if I have a problem with the office server (outage) all emails will be routed to the helm server then delivered back to the office server once available. So any incoming email wont be bounced/lost.

I have a VPS server now with 1and1.com (no wait times with tech support, and very friendly and helpful), only problem is... they haven't been able to help me resolve one of my problems.
My client has their domain registered with Network Solutions. I've already changed the DNS settings to point to my VPS where I've created the domain within Plesk. I can log into my FTP, change the site, yadda yadda yadda just like any other site. So everything works there!
Now, when I create an email account in Plesk I put in my user/pass etc... and create an email account... Great, awesome.
I go into Outlook and put in the email information, incoming/outgoing mail settings, user/pass, etc... and nothing works... It pops up and pretty much nothing happens.
What am I doing wrong for this to not work? Do I have to create a sub domain within Plesk for my domain? If so, I've already done that.
Must I change something over at Network Solutions to reflect the mail server? If so, I've added the MX records of mail.mydomain.com with prio of 10.
What is up? What am I doing wrong? :-(
Client is getting frustrated and I'm lost!
I'll keep everyone posted on the outcome :-)

I have a couple questions maybe some of you can help me with -
I have a dedicated server and many hosted customers, I want to setup SSL for IMAP email and their cpanels.
Instead of purchasing individual SSL certificates for each domain. I was thinking to just use my hostanme (eg host.myhostname.net) and direct them to that as I have seen the option in WHM.
My question is can I use an SSL cert for email that will act as a "fleetwide" SSL cert?
For example instead of using mail.theirdomain.com could I just use mail.myhostname.com and would it give them SSL without warnings? Of course they would set their email client to mail.myhostname.com..
Is it safe or recommend to use your hostname? I read somewhere to never use your hostname as a domain.. so not sure.

I basically bought a HPS Complete VPS hosting account with EuroVPS and i am having problems setting up an email client as no web mail client comes by default with that plan.
I asked the eurovps support team 2-3 times on how to set up MS Outlook as my email client for my domain and they answered the same thing and it's not working.
I was wondering,if anyone of you have HSP Complete VPS hosting account with euroVPS and is there anyway to have webmail.
As per there documentation,i am using the following:
username: user
email:user@mydomain.com
smtp&pop3: mail.mydomain.com
smtp port: 25
pop port: 110
Selected to use authentication for outgoing server and checked the option to use same authentication method as incoming server,
Deselected SPA authentication scheme
I did everything as per the documentation they sent me but it's not working,

We have a server where we host the sites and email services, and we are looking to buy a MS Exchange offsite email solution in order to have a reliable dedicated email service.
We are thinking on going with Rackspace MS Exchange solution:
http://www.rackspace.com/email_hosting/exchange_hosting
So now its the hard part, i run my own dns / nameservers at this server so if i just change the mx at my Plesk panel if my webserver goes offline my email will also stop working, correct?
And at my registrar i only can change the name of the nameservers and the ips... and also add more nameservers (im using 2 ns).
So i need to figure it out how to config/setup the rackspace email in a way that when my webserver goes offline my email can keep up working.
The rackspace support team, said to me that they can host/run my dns on their servers in order to have my email working if my webserver goes offline.
So what do you think? Its a goo idea? The only idea?
Or there are better ideas?

IIS 7.0 - I host several websites. On one of them, the email is hosted externally and not through my exchange server. I have added an MX record to point to the mail server for this domain, but I still get an error when I attempt to send an email from within my local area network. There are no problems with emails generated outside my network, but for emails generated to this domain from within my network, I get the following error:
The e-mail account does not exist at the organization this message was sent to. Check the e-mail address, or contact the recipient directly to find out the correct address.
<mail.<mydomain>.com #5.1.1>
Incidentally, the <mydomain> value does not match the domain for this email domain.
Instead it is the primary domain that I host.
I know that this must be a DNS issue, but I'm not sure how to correct.

I want to use Gmail to host my email. I have already confirmed my domain and now I can successfully send emails via my domain.
However in order to receive emails I need to add/update the MX records on my server. I did that (I think) but now, 24h later, the records don't seem to be updated yet.
For instance intodns.com still shows that there is only one MX record: [URL] ....
This is my setup where you can clearly see the MX records required by Google:
I changed the TTL to some minutes but still the changes don't seem to be propagated.
The screenshots are taken from "Website & Domains" -> my domain -> DNS - that should be the right thing to change, correct?

I registered a domain name and setup a Linux server on GoDaddy, choosing Plesk panel with Power Pack. Inside the panel I created an email address, which I can access from the webmail interface without problems. I decided to setup my clients as well, using the IMAP configuration, as I'm using multiple devices.
I followed the instructions for Outlook express and I was able to setup the account on my virtual machine, with Windows 7 and Windows Live Mail.Though, speaking of the host machine, a MacBook Pro, I normally use Apple Mail that comes with MacOS. Instructions for setting up Mail are updated back to Snow Leopard at least and they do not work properly. I tried various configurations, but I was only able to receive mail on the account, while sending won't work at all.
I'd like Parallels to update the guide or, at least, to open a KB page with the solution(s) to this issue: I googled it and found out that it is a common issue.

As my clients' needs expand, they're asking for chroot ssh/sftp setup. I'm currently on a dedicated Linux setup but don't really have the time to set up a whole new box with full virtualization or investigate a full chroot solution (baby on the way), and to be honest it would be less hassle to move to a new provider than worry about down time with sites.
What I'm looking for:
- linux hosting
- hosting for 30+ accounts, some with several domains
- at least 6 IP addresses for SSL certs
- each account in a full chroot environment (ssh/sftp/ftp) so they can't poke around each others' files, or each account set up in a virtual machine setup (ie: openvz)
- maildir
- spamassassin
- php 5, mysql, perl 5.8.8
- suexec apache would be nice

I have learnt it is harder to setup than I initially expected (since I have just moved from a shared hosting service). I am in need of some help setting up my DNS servers, as I am very confused. Here is most of the info I know:
1) I am running HyperVM
2) I've installed LXAdmin
3) I own the domain (purchased from xeodomains.com) runemart.com
4) My VPS hostname is: vps.runemart.com
5) I know my IP
6) My host has said:
'For VPS customers that have a HyperVM login you can now host forward DNS on the DNS servers rdns1.vaserv.com (US)rdns2.vaserv.com (UK'
And I am unsure what this means/how to do it.
I am not sure if I need some more information to set up my DNS, however I am sure that I can get it if I do.
Now, my questions begin. Firstly, I need to point my domain - runemart.com - somewhere. I believe I need to set up my DNS via HyperVM or LXAdmin so that they are something like: ns1.runemart.com and ns2.runemart.com. Though, is this correct? Am I able to set up my own actual domain name servers, or will my domain have to point at something like rdns2.vaserv.com?
If anyone can assist me in this I would be very greatful, as I am waiting to get my website running. This is all I will ask for now, I will take it one step at a time =).

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 have deleted the address from the /etc/postfix/virtual file and restarted postfix.

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.
