Increase default of postfix/localmailboxsizelimit
Last modified: 2017-06-19 08:23:16 CEST
Increase default of The UCR variable postfix/localmailboxsizelimit is by default unset. In this case postfix uses 50 MiB as maximum mailbox size limit for mailboxes in /var/mail/ (e.g. for users like systemmail). If the mailbox file size reaches 50 MiB, those mails remain in postfix mail queue until maximum deferral time has been reached (→ mail gets bounced). A larger default value would be better since a 50 MiB mailbox may be reached really fast by e.g. frequent cronjob mails.
This issue has been filed against UCS 3. UCS 3 is out of the normal maintenance and many UCS components have vastly changed in UCS 4. If this issue is still valid, please change the version to a newer UCS version otherwise this issue will be automatically closed in the next weeks.
Configuring Postfix' lmtp is either deprecated by deprecating Cyrus or is something the app that uses it (like Kopano) has to do. UCS' mail server solution involves installing Dovecot, and does not depend on Postfix' lmtp setting.
