<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Verdana","sans-serif"">We’re running RT 4.0.10 on CentOS 6.3 with Postfix (MailCommand: sendmailpipe) as the email solution. I mostly followed the install guide and prayed during installation and
config.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Verdana","sans-serif"">We get tickets from some external sources that when they get the autoreply from us they do a reverse lookup domain check on the Return-Path instead of the From or Reply-To
address (All three are present). The Return-Path is <a href="mailto:apache@servername.domain">
apache@servername.domain</a>, so the emails get denied since it’s not a valid domain with an external MX record. Then we get the undeliverable message from our external mail servers, complete with the raw header info.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Verdana","sans-serif"">I searched the gossamer archives but didn’t find anything solid that helped. Maybe I didn’t use the right search terms or something because I imagine this has come up before.
How can I fix this? Can I change the Return-Path? Or omit it completely? What are my options here?<o:p></o:p></span></p>
