changed from 2 -> 5 MB Thank you! Changed quota and still get same error. At the same time that sender gets message above, root on the server gets this mail: The "support" mailbox is the address in the Send copy to field and the support entry in /etc/aliases I have commented out.
Thanks. It seems to be looking for a system user, but I don't know why? Unless it's because of the STARTTLS failure in line 5 (I added numbers and spaces between lines). Not sure why that line is from sendmail, which is stopped. In this example user allen is not and never was a system user, only defined as virtual user. Immediately following we get "User unknown in local recipient table" from Postfix, then same thing in line 7 again from sendmail. In line 8 it sends the message to root, which I do get as displayed above. I am familiar with sendmail but not so much with Postfix and Maildrop, but I'm learning. Thanks for your help!!!

Apparently this is the only domain for which the Send copy to field isn't working. I tried using the Send copy to field in someotherdomain.com and it worked fine! So the problem doesn't affect customers but only me. However its a nice feature and I'd like to use it. Thanks again.
Is the fqdn of your server mydomain.com or ns1.mydomain.com? That makes a big difference, as postfix threats mydomain.com and ns1.mydomain.com as different domains, so no problems should occur. Please post the output of: grep mydomain.com /etc/postfix/main.cf to see if mydomain.com is used anywhere in that file instead of ns1.mydomain.com
