Hi Joe

it looks like two different issues. The unknown user issue doesn't seem related to you having activated debugging, as far as I can see. Also you should check if that username is expected to exist or not. If the username does not exist, then the message is correct and you should investigate your client sending that request.

The permission denied is a consequence of imap running as dovecot user without access to that file which requires root user permission. I would not change the user though. Ideally a fix should be done to avoid this message, but I believe it is harmless, particuarly if you don't have any other issues.

I don't normally run debug mode, but when I have done so, I have seen that too.

best regards

John

Back to attempting to configure this.  No doubt simple for one more familiar with dovecot and sundry stuff.

One thing I find unclear is how to set the sieve script location.  Appears to depend on other choices made earlier.

In this snippet of proposed /etc/dovecot/conf.d/90-sieve.conf, gleaned from various places on the web, seems appropriate for my setup. But, the %d (domain) and %d (user name) leave me uncertain.

The mail locations chosen earlier contain "user@somedomain.com" in the path. Don't see how the propose string accounts for that.

Also unclear is how the user script storage locations get created.  A manual administrator task, or created "on the fly" by the system, once properly configured?

And, is it required to have a "default" script and location even if none is desired?

#  sieve = file:~/sieve;active=~/.dovecot.sieve

 sieve=file:/home/vmail/%d/%n/sieve/scripts;active=/home/vmail/%d/%n/sieve/.dovecot.sieve sieve_user_log=file:/home/vmail/%d/%n/sieve/scripts;active=/home/vmail/%d/%n/sieve/sieve_error.log
