Can you turning on rawlogs?

note that if you are running older than v2.2.26, you need to use rawlog binary.

Hi,

Unsure if my previous message made it through as didn't see it on a digest.

I'm using Claws Email and 3 of 4 email accounts keep giving;

[10:50:45] POP< +OK Dovecot ready. [10:50:45] POP> USER sales [10:50:45] POP< +OK [10:50:45] POP> PASS ******** [10:50:45] POP< +OK Logged in. [10:50:45] POP> STAT [10:50:45] POP< -ERR Unknown command: *** error occurred on POP session *** Error occurred while processing mail.

I've turned on as much logging as I can find in Dovecot but nothing useful is coming out, it honestly does believe STAT is invalid - I can see the connection close rather than disconnect.

It's strange how it works for one account but not others, the settings are identical - I went through them with a fine tooth comb.

Any suggestions appreciated.

Regards,

Andrew
