I have not, yet, played with DKIM or TLS. I use weasel for two things. One is to test PMMail, the other is to relay outgoing mail to my ISP's server. The failure was doing my nightly send to test PMMail. Nothing fancy, just send mail.

That makes a little more sense. FWIW I have had older weasel versions terminate a few times. The indication was that it was doing AUTH. I never found any real information to pass on, and since it terminated, it was automatically restarted.
