I’ve been running a 空メール server for a number of years. As one might expect with a rule-based automated email reply system.. once in awhile the thing goes absolutely berserk. Usually I have to flop around the Internet trying to recover the commands I use (and promptly forget) to tame acid-tripping Postfix.
And generally this just boils down to
postqueue -p to see what’s flying through and/or stuck in the queue and then
postsuper -d ALL to clean it out.
Today, while tidying up, I came across pfqueue, a “console-based tool for handling MTA queues”. Looks great. Promptly tried it out and, surprise, surprise, while it emerges effortlessly on Gentoo, make install fails on my flavor of RedHat.
Need to figure this out. This tool could save me a ton of time.
