<div dir="ltr">I'm attempting to set up my trac installation to accept replies via email. This is the first time configuring a machine to receive mail, and I have a noobish question. <div><br></div><div>In postfix/main.conf I am asked to provide "myhostname", which the examples show as '<a href="http://mail.example.com">mail.example.com</a>'. The next config item is "mydomain", which the examples show as '<a href="http://example.com">example.com</a>'. </div>
<div><br></div><div>I don't expect much inbound mail traffic. Is it necessary to have a subdomain for mail to be received? If not, is there any gotchas with having identical values for "myhostname" and "mydomain"?</div>
<div><br></div><div>PS: I'm actually able to establish a connection to my server both locally and remote using "telnet <a href="http://example.com">example.com</a> 143" even though my "myhostname" value is '<a href="http://mail.example.com">mail.example.com</a>'. The connection fails with "telnet <a href="http://mail.example.com">mail.example.com</a> 143" since that subdomain is not configured in DNS. </div>
<div><br></div><div>Thanks.</div></div>
