Cyrus Settings


lmtp_over_quota_perm_failure: 0 If enabled, lmtpd returns a permanent failure code when a user’s mailbox is over quota. By default, the failure is temporary, causing the MTA to queue the message and retry later. I'm not sure, but maybe that's the reason (I still would like to check log files of Postfix). Nevertheless, in the recent versions of Cyrus default setting is to rejects the message (permanent failure 522) in the mailbox is over quota, so now it is the same for our Cyrus server (lmtp_over_quota_perm_failure: 1).

For your question concerning mail queue: - by default queue lifetime is 5 days - the same for bounced messages - queue run every 1000 sec (16,7 min)


Actually it's not Horde/Webmail restriction, but php. I've increased limits in /etc/php.ini accordingly:

upload_max_filesize = 10M # default 2M post_max_size = 12M # default 8M


Default quota mailboxes: employees 5000MB, others 500MB


Mail Hub


      • SYSTEMS AFFECTED
ambleve		IKOHEF	MAILHUB
almonte		IKOHEF	MAILHUB
      • ACTIONS

As root:

 postqueue -f

on both systems to flush the pending queue

Also, since (1) it may have been related due to the DNS problems yesterday and (2) it's anyway a good idea because nscd caching of DNS is conceptually broken (reverse mappings of hosts with multiple A records but different reverse names returns the wrong answer), disabled the hosts cache of nscd by setting

       enable-cache            hosts           no

in /etc/nscd.conf on both almonte and ambleve and restarted nscd
