dovecot - Oct 2017 - POP3 STAT command broken (race condition?)

Hi,

4x POP3 over SSL. I login manually using SSL client and issue STAT
command - all work.

Claws-mail works for one account persistently, the other three always
fail. There are no differences between the accounts other than
username/pass so I have been unable to determine why this occurs. Also,
Evolution works as it uses LIST not STAT.

Claws reports:

[12:30:40] POP< +OK
[12:30:40] POP> PASS ********
[12:30:40] POP< +OK Logged in.
[12:30:40] POP> STAT
[12:30:40] POP< -ERR Unknown command: 
*** error occurred on POP session
*** Error occurred while processing mail.

Perhaps there's a race between logging in and issuing commands?

Evolution works. Saying it is because it uses LIST is not something you know.
Have you tried other MUAs? Mutt? Alpine? Heck, can gmail login and import the
messages?

Since the accounts work manually, the problem seems to be Claws.

Do the accounts that not work have very large mailboxes? Perhaps Claws is
breaking because there are 500,000 emails?

Look at the STAT returns from your manual checks and see if there's a
pattern. Otherwise, I'd check with Claws.
