dovecot - Nov 2019 - Bug report

Hello,

I've got a problem fetching my emails using getmail. First question is, of
course, what's causing the problems. I'm going to think that getmail
get's an error code from dovecot when trying to connect and just signals the
most common error, so it seems to be a problem with dovecot.

Sorry but I cannot upload any files with the silly web interface of my provider,
so I cannot attach a core dump here.  :-(

Kind regards

Peter

Seems pretty clear, get mail is not running as the right user and doesn?t have
permission to change to the right user. Seems to be a configuration issue with
get mail (not sure what that is).

maybe provide getmail debug logs aswell ?

providing dovecot debug logs is not helpfull

are you using getmail with dovecot-lda, dovecot-lmtp, or just imap 
protocol ?

have lost if getmail can do any of it :=)
