I'm currently using the free hMailServer for SMTP, POP3, and IMAP. It has been pretty solid in the couple years that I've been using it. I've run it on Windows 2003 R2 and Windows 2008 Standard and Enterprise. I'm using SquirrelMail for webmail. This is PHP, but it wasn't that hard to setup. This is free as well. The best commercial experience that I had ...

http://roundcube.net/ looks pretty good and I've heard good things about it. Personally, haven't used it in any huge capacity. The other commonly used one is horde/imp which is used in a lot of various places, relatively simple from an end users point of view not so much so from a sysadmin point of view. Hope that helps.

So we send more than 10000 emails per day. Given that a day has 86400 seconds that is a seriously non-existing rate of one email per 8.6 seconds. My phone can do more. If the Ip is blocked by Spam, what I need to do. Do not send spam. Email marketing generally is seen as spam unless people approve it. Seems enough people do not. Which means your ...

The short answer is "you can't". The longer answer, from the sendmail FAQ, is How can I automatically copy messages based on sender or recipient addresses? It would require custom programming [...] Note that no such feature has been added to sendmail. When asked about this one of the sendmail developers said it was "because we still believe a ...

Sorry, but your 90% reliability of GApps is way off. If their reliability was that bad, there's no way they would have the market share they currently do. If you insist that their uptime is that bad, I'd start looking into your own infrastructure to see if something is wrong. I've been using GApps Standard (the free version) for several personal and ...

Not really a programming question, but you could try Roundcube or SquirrelMail. See also Horde.

There are so many different possibilities here. What you're really talking about is an email "stack" (much like web-server/web-app "stacks"). SMTP Agent a.k.a. MTA (Mail Transfer Agent) There are several, including Sendmail, Exim, Qmail, Postfix, and Courier. Sendmail has had most of its "issues" resolved, Exim is small and stable, Qmail is fast, and ...

Squirrelmail is probably the simplest, but that doesn't necessarily equate to ease of use. I does support IMAP though, and customizing should be do-able, it is built in php. http://squirrelmail.org/index.php

Our anti-spam system has the option of scanning our outbound mail-stream for exactly this kind of problem. We have over 20,000 students, so using webmail to send spam from our system is a problem we absolutely had before we moved them all to WindowsLive@Edu. We had the same problem you did, our outbound mailers were getting their IP reputation besmirched. ...

Server 2008 does not include any built in features for POP or IMAP, the only mail component you get is the SMTP server available for IIS. There are a number of mail servers available for server 2008, unfortunately there aren't many that are open source. Free hMailServer - as you already said it does not offer a web mail interface, but you could use ...

The simple answer is you can't. There is no native functionality in OWA in Exchange 2003 to display mailbox sizes. You could look at setting quotas to something low and setting it for warn only which would notify users that they are over quota but not limit them otherwise. You could also script your existing workaround to export users and mail them and ...

This problem can be tackled either in roundcube, dovecot or your username-backend. Roundcube has option to auto append domain parts if no domain provided (as proposed by Kondybas). But it won't too useful in your case. Of course you can patch roundcube (with PHP language) to adding your logic. Dovecot has option to strip domain (as proposed in Dovecot ...

Which MTA (Mail Transport Agent) you use should have no bearing on your choice of MUA (mail user agent) although note that the MTA typically needs an additional component to route receiving mails to the MUA (a delivery agent/pop/imap server). Although it was some time ago, I did some research using real systems to measure effectiveness of different MTAs ...

It sounds like forms based authentication is turned off or is not working. Start by making sure that forms based authentication is enabled on the Exchange Virtual Server under the HTTP protocol of the server in ESM.

You might consider Rackspace's email service: http://www.rackspace.com/apps/email_hosting/rackspace_email/ Or you could leave your email on Google Apps, and use a personal web-mail client like RoundCube to access it...

You don't need "a webmail". (It's actually "a webmail client", by the way). As AliGibbs said, you need a mail server. Here's instructions on how to install ad configure Postfix for CentOS To explain to you the difference and answer some of your questions: A mail server like Postfix is designed to handle sending and receiving of emails. It uses the SMTP ...

For setting up your email server and webmail, you need two things: an SMTP server, to send out messages, as you said, a way to read the received messages, that's the part you're actually asking for. The webmail will not actually be receiving the messages, it will only read or fetch them from somewhere. It is the smtp server (usually the same as the one ...

sendmail : How to copy outgoing messages using milter Consider using an archiving milter: https://www.milter.org/milters/archiving/alphabetical/1 In standard non set root uid installations milter can process/archive all messages passing via sendmail server.

xampp on windows 8. That smells like a home setup instead of a proper server, domain and mail config. This will fail horribly for email as many providers will block mail sent from home DSL connections due to spam issues. So don't do this. If you really want your own mailserver, get an el cheapo VPS with a proper mail setup on it.

there is another tool that replaces the missing Microsoft POP3 Server in Windows 2008. Visendo SMTP Extender is available as a free community edition and a plus edition, which you can use for free for a demo period of 30 days.

The only thing I can think of is the SMTP verify command which allows a remote server to check if an email address is valid or not. See http://www.postfix.org/postconf.5.html#disable_vrfy_command.

I've never heard of an MTA "leaking" email addresses, unless the entire server is compromised, in which case they will get all your addresses, not just two alias's. Personally what I feel is far more likely is: The spammers just hunted randomly for an email address The company that knows of these email addresses has made an honest mistake Of course no ...

Yes. This is very commonplace. You need to use an MX record (Mail Exchanger) to indicate that you want your emails to go to a different location. The rules for MX records are as follows: They must point to an A Record They must point to an A Record, not an IP Address They must point to an A Record, not a CName So if your mail server already has an A ...

I'm not sure where this 90% uptime came about, but Google Apps (even the personal edition) is very reliable. More so than other commercial equivalents. The <10 times that GMail has had issues were widely publicized due to the rarity of this happening. Even with this downtime, it still beats out other alternatives like Hotmail (Windows Live) and Yahoo. ...

Yahoo has a "business" class service that lets you use your own domain. I had a client that used this and was happy with it, but they switched away when they got acquired. Fast-email.com has some business services that let you use your own domain. I have a friend that uses them and likes them, but he has their personal plan. I'm sure other e-mail ...

Having tried Squirrelmail and Roundcube I much prefer the latter. They're about as easy as each other to set up but Roundcube in much nicer to use.

Add that entry as an A record in your DNS server. Assuming this is Windows, go into your DNS manager, and open your forward lookup zones. Add a New Host (A). Put in the servers FQDN as the name and it's LAN IP as the address.
