I think that squirrelmail and horde would do a good job for webmail.
There shoudn't be any troubles having some redundancy for DNS, web servers, mtas, but what about IMAP/POP? linux-HA? MySQL replication should be enough, I guess. Or maybe linux-HA as well. I wonder if I should add GFS to the mix to have multiple IMAP/POP servers use the same storage. Or maybe IMAP proxies?
Any insights welcome :).
Hi Ugo, Congrats on your plan opening the ISP. For webmail, a professional touch would be nice for your customer. Instead of using plain squirrelmail, try using http://www.nutsmail.com/ instead.
AFAIK, redundancy for mail server seldom uses linux-ha/any other failover stuffs. It is most common to use 'backup MX' in DNS settings. So, when the main server in unreachable, the sender mail server would try to the secondary MX through DNS query.
