Hello!

While searching for an explanation for the fact that after updating to
Dovecot 2.3.17_1 (FreeBSD 12.2) I suddenly stopped receiving emails and
following error messages appeared in the dovecot.log,

/Error: lmtp-server: conn unix:uid=125 [1]: rcptu...@domain.tld:

But what exactly does your answer mean for those affected?

That all users who use Dovecot and use the whole thing without
"mail_home" and only with "mail_location", must wait until a BugFix
appears to be able to receive emails again?


Thanks in advance and have a nice advent sunday
Volker

P. S.:
In my case dovecot -n shows

/mail_location = maildir:/var/mail/vhosts/%d/%n//
//mail_home = /var/mail/vhosts/%d/%n

/so mail_home is even set!/
/


You can roll back to 2.3.16 as well?

Aki

After looking bit more, this issue is fixed and will be in 2.3.18. If you want, 
you can try applying

https://github.com/dovecot/core/compare/98f709de%5E..d36d2c59.patch

which should fix this issue.

In the running config userdb does not return the field “home” and 
therefor a user does not have a “mail_home” only a “mail_location”.
If i change the config to provide a “mail_home” it works, but due to 
the directory structure i can not change this yet.


Problem confirmed. This is a 2.3.17 regression. Tracking internally as
