Redundant EMail Service

Jun 11, 2009

We are a hosting company in Colombia, and we want start selling corporate email service.

The main idea is have two servers with redundance, I think this servers have to share the filesystem I don't know if using a scsi disk or just a network file system. We also want to have a good appliance for stop the SPAM, Im not so sure if we need to have redundance on it, its ideal but we are just starting the bussines and we dosn't have cliets yet.

Can anyone share their setup with us, and give us recomendations or tips?

Another option is, if someone know how to do that and have implemented this setup before and want to work $$ with us to implement that, please contact me to jbravo[at]colombiahosting.com.co

Email Service

Jun 13, 2009

I am trying to find the best economical solution regarding my email address but I need some advice pls.

I have a very small package with asmallorange and I have set up one of my business email in it. I didn't calculate that this business email could take so much space. I have some assistants which work in other places. One of my problems is these asistants who need to access this address too, are not allowed to access any free email provider like gmail, yahoo at their work computers because of their work policy. So I can't do forwarding and I need to have this email address under my domain.

I am thinking of these options:

1) Get more space . This will become expensive for me.

2) use a dedicated email service under my domain name.
I have no experience here and I wonder if using a gmail service under my domain will be blocked for my collaborators.

3) change host ( I am afraid to lose my data and my website database).

Service To Check If An Email Is SPAM

Jun 25, 2008

We have a script that will be sending out emails from our server. A few already have hit the Outlook SPAM folder. The email that's sent is a validation check, where the user has to click a link to verify an account.

Is there some service out there where you can send it your email and it will tell you if and then why it will be caught by leading spam filters?

Hosting A Public Email Service

May 10, 2007

Currently we are running a very successful site for extreme sports. We have just spent 6 months on development of our new site which we will launch in a fortnight. This will free up some of my time to look at other areas and avenues to attract members.

Personally I would love to run a hotmail style service on our website, and believe this would help with the growth of our online community.

Just interested in advice from others on areas to be aware and alert when running a service like this?

I am also trying to make the decision between SocketMail or Atmail. If anyone has opinions on these, or an alternative solution i'm all for that advice too.

Basically at this point I am wanting to get as much advice together as possible, then look to making an informed decision to go ahead or not.

Currently we operate off a dedicated server and i realise this may have to become two servers in the near future with such a service. It is fully managed by myself, and a 3rd party individual I hire to maintain the server on a monthly basis.

Setting Up Free Email Service And Storing Mails In MySQL

Feb 14, 2007

I have a busy dating website with 30 000 registered users and ~200-600 users online all the time. I would like to offer free email with ~10 MB mailbox to all users.

I have an idea to use scripts provided by b1gmail.de. Its similar to Hivemail or Socketmail. It uses only one POP3 catch-all mailbox and stores all emails in MySQL database, including attachments.

My worries are about MySQL. If I have 30 000 users and each user has some 5000 messages in his/her mailbox:
30 000 x 5 000 = 150 000000

That's 150 million rows in one table!

I know, not all users will have 50000 messages in their mailboxes, but the number of users increases about +2000/month.

I can't imaggine how long time will need MySQL to find messages for each user in the table with 150 000000 rows.

I don't know - maybe it's not a problem at all. I just never had such large tables and I don't know if it's possible at all.

Another problem: I have Fedora Core 2 installed and even don't know yet if it supports files larger than 2 GB.

Maybe it's better to set-up normal POP3 mailboxes for all users instead of using one catch-all box and storing data in MySQL?

do not post warnings about spammers. In the beginning I'll provide email addresses only to "gold" members. I opened this thread because I don't want to set-up a system which will hang after a couple of months because MySQL will not be able to handle it or I will have other unknown problems.

Plesk 11.x / Linux :: Email To External Mail Service Delivered Locally

Oct 7, 2014

Plesk delivering email locally to a not existing mailbox instead of sending it to an external party. First I was using a local mailbox, but my client wanted to control the email using their own server. So I've changed the MX records to this new server. Deleted the inbox in Plesk and turned off Mail support for this domain.

New situation: DNS server for domain.com is hosted on a different location and points to my Plesk server for the website and the MX records point to the clients server for the mail.

Email send from email addresses like gmail are send correctly to the clients server. Email addresses from my PLesk server and forms from the website are send locally.

Redundant DNS

Oct 6, 2009

I have been working on and designing a hosting company. Now setting up my names servers has came to a question. When I ran a previous business with a partner he only use Name Servers on 1 Machine in 1 location.

Now my question is my first server is going to be located in New Jersey, USA . So that is where My first set of DNS starts. With my previous partner I noticed most of the customers were based in Europe, Philippines, etc. Over seas. Now What I am asking is Will a VPS in a different location work for DNS Server. That way I can keep a lower budget till we get a few customers under out belt.

Redundant DNS Servers? How Do You Set Them Up

Apr 8, 2009

Because of the attack on theplanet yesterday, my sites were down.

People are mentioning adding "redundant DNS servers" to protect against downtime in future attacks.. but I haven't found any info on how to set these up.

I also seen somebody post that the planet doesn't allow "zone transfers" so I'm a bit confused at how to proceed.

I just registered an account at [url] and I'm unsure on where to begin. Their FAQ is just a large photo.

My .com is registered at Godaddy. Do I edit records at godaddy to point to the server IP? Or do I have to edit records via WHM?

Redundant Hosting ....

Aug 13, 2009

I currently run spiderloop.com a SEO control panel designed for windows hosting accounts. The site and web service is hosted on our own server and works great, however I am concerned about redundancy and do not want to purchase a whole other server just to be fail safe. So I am going to purchase a shared hosting account to facilitate redundancy.

So here is the question.

How do I do it? How do I set up my current host to redirect to the new host when it goes down?

If the current host has problems how can I force the users browser to redirect to the redundant host? I simply don't understand.

Redundant Config

Mar 18, 2007

I've decided to move from managed hosting to colocated hosting and I'm in a bit over my head as far designing the server configuration goes. I'm looking for assistance with setting up a fully redundant configuration with no SPOF (single point of failure).

The colo provider ensures full redundancy to the cabinet, terminating with two network drops from diverse bandwidth providers and HSRP. I need to eliminate all SPOFs inside the cabinet.

Some questions...

1) I'm thinking of using the Cisco 2960 Series switch as the in-cabinet distribution switch. I believe it supports HSRP. From my understanding, the switch will automatically failover from one uplink to the other in case of a network problem on one of the uplinks, and this will all be transparent to any servers connected to the switch. Is this correct?

2) However, this introduces the switch as SPOF. So, I believe what I need to do is ask the colo for a second pair of network drops and deploy a pair of 2960's. Then I would connect each server to both switches via separate NICs. Is this correct?

3) Finally, assuming I am on the right track here, I would like this to all be transparent and automatic with no human intervention required to recover from a switch failure. The servers will be running RHEL 4. How would I configure the network interfaces on the servers so that they can transparently use either (or both) of the switches? Is there some way to assign the same IP address to more than one interface? How does the OS keep from getting confused about where to send the traffic?

Thanks in advance for any insight. I would also be happy to hear recommendations for excellent network consultants that I could hire to design and implement this configuration for me.

Redundant Server

Sep 15, 2007

I have two servers. One hosts about 55 small sites and the other does nothing.

Can I make use of the spare one to take over automatically if the main server fails for whatever reason?

I had been thinking of using Rsync to backup accounts / mail every 6 hours or so and then manually changing the nameservers on the domains in the event of server1 failing. Would that even work? Then I got thinking about it all being automatic.

Redundant VPS Solution

Apr 14, 2007

I have a few VPS's, the main one has cPanel/WHM and runs all my sites / email / DNS and MySQL DB's. Heres a little info:

VPS1 - CentOS 4.4, cPanel/WHM, runs all domains (OpenVZ)
VPS2 - CentOS 4.4, Webmin, Slave DNS to VPS1 using Webmin cluster (OpenVZ)
VPS3 - CentOS 4.4, Webmin, Slave DNS to VPS1 using Webmin cluster (Xen)

However, if VPS1 fails for say 24 hours, im screwed!

So, my question is can I get some kind of redunadancy built in somewhere. For example if someone is trying to access my domain "mydomain.com" and the main VPS is down, then the request for the site would go to VPS2, or VPS3...

The same for the mail server, if some is sending mail to one of the domains on the VPS, and the main VPS was down, the mail would be sent to my other VPS's.

I just don not like the fact there is a single point of failure!

I do have WHM managed Weekly and Monthly backups of all cPanel accounts etc.

Redundant Network Cards

Aug 29, 2007

to setup a Windows server that can support the failure of the switch that comes before it in the network diagram. The idea would be that if the 15A circuit the switch was on failed, or the switch just died, the server would still be online.

I already have two switches in spanning tree just before the server. Is there a way to assign a single IP to the server on both its network cards and connect each card to a different (spanning tree'd) switch?

Redundant Router Setup

Jun 5, 2007

I'm in the process to setup a new service with an ISP with the following scenario and need your help.

I've got the rack (42U), servers and switches. Only routers has been left and here is that I need your help.

I have also 2 ports from the ISP where I can connect my routers. I need to get 2 router devices with auto sync feature in order to be able to setup a redundant plan in case that one of them goes down.

Those routers should have firewall features too in order to avoid setup iptables rules for each server. A basic DDoS protection is needed too.

I'm going to push around 100Mbit of traffic across the servers but that will happen after 3-4 months from the initial setup. In the first instance no more than 10-20Mbit will be used.

I heard a lot about Cisco but got no idea what model is the most suitable for my case. I will probably need a module for DDoS attacks and another one for advanced security IOS from what I read but it is not clear to me.

Looking For Redundant Setup, Round Robin?

Nov 5, 2008

Looking for redundant setup, round robin?

I'm looking to make high availability setup, and wondering how many of you have made it so?
we are looking to multi-home the page with a round robin setup, using multiple VPSs/dedicated servers geographically different locations.

Right now i'm still looking at "stale" DNS setup, no automanagement of servers down. Is there a service/software which already offers automatic changes of zones for removing servers which are down, and adding them back when they get back online?

Do i need to custom tailor everything?

Redundant Apache (failover System)

Sep 22, 2009

I currently own several servers: let's say sites on 3 of those servers rely on a website that sits on server 4

If server 4 goes offline, then servers 1 2 and 3 suffer a lack of usability.
The website on server 4 is very small and fast, but receives several hundred thousand visits a day

I figured it would be a good idea to replicate that website on each of my servers, but I'm unsure about how to set up a good redundancy system..

Using several nameservers doesn't work as expected (visitors are randomly sent to one of the nameservers, in no particular order)

Does Anyone Exceed 80% On Primary/redundant Circuits

Oct 18, 2009

So the rule of thumb is if you have a 30A circuit to not exceed 80% or 24A.

If I buy a 30A circuit, I am assuming it is protected by a circuit breaker that is 30A, correct?

In *theory* we could run 29-30A all day and be fine.

So, I understand, the rule of 80% to be to the effect that "during startup, equipment uses more power ... or during runtime if it heats up, the fans go faster using more power" so it is safe to be at 24A in case you get spikes to 27-29A.

Is my reasoning correct?

Further, if you run primary/redundant circuits, is there really harm in running 13A on one circuit and 14A on the other.. and in the unlikely event of a failure, you are running 27A on one circuit (at 90% instead of 80%).

Any thoughts on this? Getting an extra 3A out of a 208V circuits is like putting in 3-4 more servers. If someone is doing this please let me know. I think it would work fine but i would like to know from the experts that do the colo stuff for a living what problems i could encounter, if any.

Setting Up Redundant Mirror/Mirroring Server

Jul 7, 2009

I have a LAMP server running and would like to have the exact mirror running on another location. I would like to sync the web files and database in either real time (upon any update) or in delayed mode (x minutes after the update).

For MySQL, I believe replication can do the job unless anybody has better recommendation. What would you guys suggest for web files? Can I use different Linux flavor but maintain back the same LAMP version?

Is there any "online" 3rd party load balancing service that I could use to load balance the traffic to both servers?
