-----------------------+---------------------
 Reporter:  essandess  |      Owner:  (none)
     Type:  defect     |     Status:  new
 Priority:  Normal     |  Milestone:
Component:  ports      |    Version:
 Keywords:             |       Port:  postfix
-----------------------+---------------------
 {{{postfix}}} fails to launch after every update because the file
 {{{maillog_file = /opt/local/var/log/mail/postfix.log}}} (set by
 {{{/opt/local/etc/postfix/main.cf}}}) is created with incorrect
 permissions.

 Diagnostics after update:

 {{{
 $ sudo port load postfix
 # port 25 fails to open
 $ sudo less /opt/local/var/log/mail/postfix.log
