I've started seeing the following error in mail.err for precisely one user on precisely one domain:

In mail.log I see a bit more: Warning: Failed to parse address from `From_'-line: Missing domain Error: mkdir(/var/mail/vmail//jeff/mail) failed: Permission denied (euid=1000(jeff) egid=1001(jeff) missing +w perm: /var/mail/vmail/, dir owned by 4000:4000 mode=0755) Error: mkdir(/var/mail/vmail//jeff/mail) failed: Permission denied (euid=1000(jeff) egid=1001(jeff) missing +w perm: /var/mail/vmail/, dir owned by 4000:4000 mode=0755) Error: Mailbox INBOX: Failed to autocreate mailbox: Internal error occurred. Refer to server log for more information. save failed to open mailbox INBOX: Mailbox INBOX: Failed to autocreate mailbox: Internal error occurred.
And yet there's no apparent problem sending and receiving mail for user jeff, for all domains handled by the server. Other users have no issues. The /var/mail/vmail/ hierarchy is all owned by vmail:vmail (4000:4000) and directories are all 0755. I suspect a red herring except it's been continuing for a week now. I was reading this page (following some searching), but it doesn't seem pertinent in the end.

Any suggestions what this might be?

This indicates your mail process is being ran as jeff:jeff instead of vmail:vmail.
Can you try doveadm auth test yourusername and doveadm user yourusername to ensure you are not ending up with uid=jeff gid=jeff somehow?
