#6 Updated by Filippo Carletti almost 6 years ago

  • Change "Queue message max size" option to something bigger than 100MB
Set to 200MB in server-manager. Check:
  1. config getprop postfix MessageSizeMax
    200000000
  • Try to send an email with an attachment bigger than 52MB

Sent a SMALL email of a few bytes, it remains in queue with the same error listed above:

Jan 29 16:39:36 nsrv64a2 postfix/local[7423]: fatal: main.cf configuration error: mailbox_size_limit is smaller than message_size_limit
Jan 29 16:39:37 nsrv64a2 postfix/master[2432]: warning: process /usr/libexec/postfix/local pid 7423 exit status 1
Jan 29 16:39:37 nsrv64a2 postfix/master[2432]: warning: /usr/libexec/postfix/local: bad command startup -- throttling

  • The mail is not delivered and remains in queue

The mail remains in queue even if it's small:

[root@nsrv64a2 ~]# mailq
-Queue ID- --Size-- ----Arrival Time---- -Sender/Recipient-------

#7 Updated by Filippo Carletti almost 6 years ago

The mail remains in queue even if it's small:

As soon as I updated to nethserver-mail-common-1.3.1-1.0gitbccef5e2.ns6.noarch the mail has been delivered.
Then I sent a big mail and it has been delivered.
