When SMTP sending authentication is set, it is impossible to send emails to external domains outside the firewall.

You can use the following command to perform a test:

1) Telnetyourserverip 25, 220 ************************************** ****

2) enter the EHLO command, and the 502 unimplemented (#5.5.1) is displayed)

Solution:

Disable Mailguard in Cisco PIX (which limits the minimum set of SMTP commands to a specific command. cisco's PIX Firewall allows the Mail Guard feature by default. This feature enables internal email servers to receive only commands HELO, MAIL, RCPT, DATA, RSET, NOOP, and QUIT in section 4.5.1 of RFC 821, all other commands are rejected, and the response code is "500 unknown commands ". Auth login is also a command out of section 4.5.1 of RFC 821. In this case, you can use the no fixup protocol smtp 25 command to delete the SMTP protocol repair settings in the configuration to disable protocol repair.
