Hi. The address you are sending from is deferred in the recipient's mail server, because the domain does not exist. Do you have a MX record for the sender domain?

Following is the maillog from the /var/log Sendmail [102342]: psfafEADaAd: to=<[email protected], delay=02:00:29, xdelay=00:00:02, mailer=esmtp, pri=79782, relay=relay-ex2.cch.ca.

Meaning emails to [email protected]<mailto:[email protected]> will go out and but sometimes emails with [email protected]<mailto:[email protected]> are not going out. We could be wrong...problem could be somewhere else. Any help will be really appreciated. Thank you.
