    See above comments. If you want to run Postfix instead of Sendmail, then run

    and set Postfix to be the active MTA.


  • It looks to me like a cron job on attempting to fetch mail from encountered a message larger than the limit set in the local .fetchmailrc file. The oversized message should be at in whatever mailbox fetchmail was configured to poll at that server.

    However, see the reference to Postfix above. Also, sendmail is not running on this server:
    [tim@helen ~]$ sudo service sendmail status sendmail is stopped sm-client is stopped

  • You can do

    mailbox_size_limit = 0

    which will mean “unlimited”

    Just mentioning.
