I have a smarthost with Getmail+Postfix+Dovecot.
And i am receiving from some user accounts at my remote mail server this message when i am downloading to my smarthost:
Delivery error (command sendmail 91677 error (75, postdrop: warning: uid=501: F$ sendmail: fatal: userX_server(501): message file too big))
This message is the result from Sendmail that is sending mails from Getmail to Postfix, both in the same machine.
Getmail is set to download mails from my remote mail server to my smarthost.
I am able to use sendmail, but i cannot even find any path to sendmail config (searching from sendmail.cf).
This machine is using OSX 10.9.5.
