Description Brian J. Murrell 2017-09-14 13:32:00 UTC

Description of problem:
The patch in https://src.fedoraproject.org/cgit/rpms/esmtp.git/tree/esmtp-1.2-localhost.patch?h=f25 is having unintended consequences.

If I try to send mail to <user>@access.ironport.com I get:

DNS lookup failed: Name or service not known

Version-Release number of selected component (if applicable):
esmtp-1.2-5.fc25.x86_64

How reproducible:
100%

Steps to Reproduce:
1. On an F25 machine configured to use esmtp, try to send mail to example.com

Actual results:
DNS lookup failed: Name or service not known

Expected results:
Should send the mail, like esmtp 1.2 does without the aforementioned patch.

Additional info:
$ dig access.ironport.com. any
