Postfix: “queue file write error”

If you get an error like:

Aug 21 12:41:03 webb4 postfix/sendmail[11234]: fatal: web1_user(12967): queue file write error

in your mail log, then the vale for message_size_limit in postfix is too low. Edit postfix

vi /etc/postfix/

and set the message size limit to a higher value. E.g.

mesage_size_limit = 900000000

and restart postfix:

/etc/init.d/postfix restart

If there is no message_size_limit set in, just add the line.

  1. Wonderful! Solved my problem right away.

    Originally thought it was because my mail error logs had to just be cleared.
