I'm working to get Dovecot 2.0.13 working along with qmail, Vpopmail and Squirrelmail on a Debian 6.0.2 system, Dovecot compiled, not from a package.
Vpopmail has a widely known assigned user/group ID of 89 and is the owner of all the mail folders.
Regardless of value of first_valid_uid (1, 89, other), Dovecot denies Squirrelmail connection, saying it can't allow access to UID 89. "Couldn't drop privileges", it says. I'd be grateful for fixes, suggestions, or a pointer to an existing answer to this problem. Thanks ahead. :)
Presently dovecot -n shows:
