So I think I have masquerading setup properly in sendmail... However, the
cron daemon sends mail from the root account with the canonical domain name
as the right-hand side of the address. This goes against the masquerade
configuration which should have it appending the subdomain name only.
In sendmail.mc (excerpts):
I am using RHEL AS 4 and sendmail 8.13.1.
With this config, I receive emails from cron sent 'from: Cron Daemon
[[log in to unmask]].'
Any help would be appreciated.
