CSSMTP flags syntax error on HELO / EHLO command

Troubleshooting


Problem

CSSMTP generates an error report for syntax errors on the HELO / EHLO command. If there is a valid HELO / EHLO command earlier in the JES spool file, emails might still be accepted by CSSMTP.

Symptom

After processing the command 'HELO domain_name mm/dd/yy', CSSMTP generates an error report that contains the following:
501 5.5.4 JES Syntax error. Too many args after 'HELO' command

Cause

CSSMTP expects the HELO / EHLO command to follow the syntax as described in RFC 2821.

Resolving The Problem

Valid syntax for HELO / EHLO is:

HELO domain_name

EHLO domain_name

where domain_name specifies the domain name of the sending host.
