abrtd - configure email?

[cherdt]

abrtd recently caught a segfault and sent a notification via email from user@localhost.example.com to root@localhost.example.com. An MTA between this host and my email decided it didn't like that domain -- there's no localhost.example.com in DNS -- and rejected the message.

I don't see any options to set sender or recipient addresses in /etc/abrt/abrt.conf or in /etc/abrt/plugins/CCpp.conf (according to the report, the analyzer was CCpp). (I've never used abrtd before, but figure that if a process segfaults on one of my hosts, I should probably see the notification.)

I realize this may not be an abrtd-specific issue, so I've tried to verify that the hostname is set correctly in the usual places. The correct FQDN is returned by:

• hostname
• cat /etc/hostname
• the gethostname function (which is used by postfix to determine the value of $myhostname)

/etc/hosts only has entries for localhost.
