Deferred: 421 Too many concurrent SMTP connections;

[lyager]

I just want to add that I've had this issue with verification emails twice. Once with Ticketmaster, and the other with Discogs.com.

Discogs were kind enough to add a screenshot from the logs (attached here) stating that their verification email gets blocked by Spamgourmet

With Ticketmaster it was worse. They decided that it was time for me to update my password, apperantly because of some suspecious login attempts - the only option was the recovery email.

Anyway, I assume the recovery email systems are not programmed as robust as a normal SMTP server, which whould gladly retry after some time.

Anyway, just wanted to add to the thread. I've had the same issue - and knowing that Spamgourmet is free, I don't know if we're at the point where this would be too much to ask to fix?
