I have wasted weeks to months of time on postfix + dovecot, SSL, non-DUL IPs, spam, etc.
Oy, letsencrypt with dns challenge and nsupdate have me automated on the SSL side, proxy for spam, all I care about is the first two now. Yeah, not an easy task, but paying for a spam proxy took 90% of maintenance away.
Well the really hard thing about SSL is sni maps, at least when working the first time with it and trying to debug it (especially with Thunderbird desktop which still wrongfully reports an invalid certificate 50% of the time. Click on refresh and it suddenly says it's okie-dokie)
