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]: rcpt user@domain.tld:
duplicate db: User user@domain.tld doesn't have home dir set, disabling
duplicate database//
//
//Dec 12 08:42:54 lmtp(user@domain.tld)<80363><z7AxDf6ntWHrOQEAp6O1gg>:

/I found your answer here
<https://www.mail-archive.com/dovecot@dovecot.org/msg84893.html>:

/Problem confirmed. This is a 2.3.17 regression. Tracking internally as
DOP-2659./

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

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?

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.
