It's been awhile since I looked into it, but I recommend outsourcing your email. <br><br>Companies like fusemail (<a href="http://www.fusemail.com/solutions/resellers.html">http://www.fusemail.com/solutions/resellers.html
</a>) will give you accounts at $0.69/month/account for a 1GB account (last time I checked anyway). They provide an API and a dashboard for managing it. They also handle backups, I believe (read the fine print before you trust me). I think there is spam filtering and anti-virus built in too.

Hi,<br><br> I will probably have to design an e-mail (and other components)<br>infrastructure for a small ISP soon (WISP).<br><br> I'm doing some research to determine which components would be best to<br>
offer e-mail services to their client and allow the staff to manage<br>accounts easily.<br><br> I usually use virtual machines a lot for isolation and easy backups and<br>migration (when a hardware node is underpowered, it is easy to migrate
<br>one or more virtual machines to another hardware node easily).<br><br> I have looked at iSCSI and drbd for high-availability of the storage:<br><a href="http://www.pcpro.co.uk/realworld/82284/san-on-the-cheap/page1.html" target="_blank">
http://www.pcpro.co.uk/realworld/82284/san-on-the-cheap/page1.html</a>.<br><br>This looks like it should be doing a great job of high availability storage.<br><br> For mail server, I guess I should look at an MTA and IMAP/POP server
<br>that supports LDAP and/or MySQL for users. Postfix should be a good<br>choice for MTA, as I know it (at least a little, but I know sendmail<br>better). For IMAP/POP, I'm not sure... Would dovecot be sufficient, or
<br>should I try cyrus. I'd rather use components that are available for<br>base or extras repository (or rpmforge). I think that squirrelmail and<br>horde would do a good job for webmail.<br><br> There shoudn't be any troubles having some redundancy for DNS, web
<br>servers, mtas, but what about IMAP/POP? linux-HA? MySQL replication<br>should be enough, I guess. Or maybe linux-HA as well. I wonder if I<br>should add GFS to the mix to have multiple IMAP/POP servers use the same
<br>storage. Or maybe IMAP proxies?<br><br> Any insights welcome :).<br><br>Ugo<br><br>_______________________________________________<br>CentOS mailing list<br><a href="mailto:CentOS@centos.org">CentOS@centos.org
