Hi All,<br><br> We are encountering a issue with sendmail in RT. Following is the maillog from the /var/log<br><br><br>Sendmail [102342]: psfafEADaAd: to=<mary@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@rt.domain.com>: Sender address reject: Domain not found<br><br>We are suspecting it is a issue of sending emails to subdomain email addresses. Meaning emails to abc@xyz.com will go out and but sometimes emails with abc@lmn.xyz.com are not going out. We could be wrong...problem could be somewhere else.<br><br>Any help will be really appreciated.<br><br>Thank you.<br><br><br><br><br><br><br> </body>
