[Dovecot] Dovecot login slow

[Gregory Sloop]

Is it perhaps a *server* dns lookup delay?

I've typically seen 60s delays when a reverse lookup fails, so 20s
seems odd - but when you first mentioned it, that's the little flag
that waved in my head.

'course I could be totally stupid, high, or huffing glue or something
- but thought I'd throw that out there.
