quota-status: Issues with uppercase recipient address

10 Mar 2018


      Hello list,
Dovecot Version: 2.2.34 (874deae) on FreeBSD
MTA: Postfix 3.3.0
I've got an issue with the quota-status service:
Something breaks when receiving mail with a recipient address that includes non-lowercase characters,
for example foo@Example.com instead of foo@example.com:
postfix log:
postfix/smtp/smtpd[83387]: NOQUEUE: reject_warning: RCPT from mout01.posteo.de[185.67.36.65]:
450 4.7.1 <foo@Example.com>: Recipient address rejected: Invalid user settings. Refer to server
log for more information.; from=<[REDACTED]> to=<foo@Example.com> proto=ESMTP helo=<mout01.posteo.de>
dovecot.log:
quota-status(foo@Example.com): Error: User initialization failed:
Namespace '': mkdir(/srv/mail/Example.com/foo/mailboxes) failed: Permission denied
(euid=1001(vmail) egid=1001(vmail) missing +w perm: /srv/mail, dir owned by 0:1001 mode=0755)
The user_query has already been altered to include L, however the issue persists.
user_query = 

SELECT CONCAT('/srv/mail/','%Ld','/','%Ln','/') AS home, 

1001 AS uid, 

1001 AS gid, 

concat('*:bytes=', quota) AS quota_rule 

FROM mailbox WHERE username = '%Lu' 

AND active = 1
Thank you for any suggestions.
Christoph
