Having run my log file analyser for a couple of days, I can only tell you, it’s a big relief to know, when sslfingerprints are alright and when they are not and also how to fix them instantly.
I am checking my e-mail not by looking at my dozens of IMAP folders, but I check my e-mail by looking at a procmail log file converted to look like a emacs diary, at least my special version of an emacs diary. My procmail log file “tailf viewer” stalls every now and then, because its “ssh father process” stalls. Right before restarting this procmail log file viewer is the right time to run my fetchmail log file checker.
Sure, I would love to get informed of fetchmail sslfingerprint problems instantly – why not through XMPP, i.e. sendxmpp?!! This kind of problem needs to get addressed w/o undue delay.
Remember: fetchmail mostly runs as a silent demon, fetching and forwarding e-mail, leaving messages in its log file – but who surveys fetchmail’s log file? I don’t think creating messages outside its log file is in the spirit of fetchmail, so there is really no alternative to surveying that log file. Have you already started?
