Since the doevcot update to 2.3.17 i get a panic if a mail is delivered with lmtp. In the logs i get these messages:

lmtp(rcpt@example.com)<21067>: Error: lmtp-server: conn 10.0.0.105:52981 [1]: rcpt rcpt@example.com: duplicate db: User rcpt@example.com doesn't have home dir set, disabling duplicate database lmtp(rcpt@example.com)<21067>: Panic: file imem.c: line 65 (i_strconcat): assertion failed: (str1 != NULL) lmtp(rcpt@example.com)<21067>: Fatal: master: service(lmtp): child 21067 killed with signal 6 (core dumped)

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 DOP-2659.
