[rt-users] Sendmail - Sender address rejected: Domain not found

[Yaj Tap]

Hi All,

 We are encountering a issue with sendmail in RT. Following is the maillog from the /var/log


Sendmail [102342]: psfafEADaAd: to=<mary at cch.ca, delay=02:00:29, xdelay=00:00:02, mailer=esmtp, pri=79782, relay=relay-ex2.cch.ca. [IP Address], dsn=4.1.8, stat-Defferred: 450 4.1.8 <apache at rt.domain.com>: Sender address reject: Domain not found

We are suspecting it is a issue of sending emails to subdomain email addresses. Meaning emails to abc at xyz.com will go out and but sometimes emails with abc at lmn.xyz.com are not going out. We could be wrong...problem could be somewhere else.

Any help will be really appreciated.

Thank you.
