- I have a disturbing uid/gid issue: up until dovecot-2.3, dovecot changed its uid/gid to the user it is delivering the mail for. I'm the first user on the system with uid 1000 and the users gid is 100. Therefore I kept first_valid_uid = 1000 and first_valid_gid = 100. Now that I've upgraded to dovecot-2.4, it immediately started to complain about unable to change uid/gid, because it tries to write in user's directory as mail:mail. Mail directories and files in it are accessible only by the owner, not even by the group. So even after lowering first_valid_uid/gid, the operation fails.
Are there any configuration options to restore dovecot-2.3 behavior to change uid:gid to the actual user

- I know, that mbox is deprecated as of dovecot-2.4 - or that it has been long superseded by more modern formats, but I have a setup for 20+ years (without any problems and less files) and before I would convert it to Maildir, I'd rather provide a transition period and keep using mbox for a little while.
During dovecot-2.3 times this was my mail_location setting: mail_location = mbox:~/mail/:INBOX=/var/spool/mail/%u Mails get delivered into /var/spool/mail/user and when dovecot reads them, they get copied under /home/user/mail.
Now for dovecot-2.4 I'm forced to came up with this: mail_driver = mbox mail_path = /home/%{user}/mail mail_inbox_path = /var/spool/mail/%{user} #mail_home
Are there anyone else with a setup like this struggling with dovecot-2.4?
Thanks: Dw.
