Is the traffic coming through a firewall? Some will not allow ESMTP commands through. Our Pix did this. Any ESMTP commands were replaced with XXXX. This feature can be disabled in Pix, but I don't recall how to offhand. Google can probably give you the answers.
Rob -----Original Message----- Sam and others, Below is a further sampling from my logs or a recurring ESMTP 502 error. Of note is the same attempted command XXXX. The listed servers are typically running various versions of sendmail (typically 8.12.1) or MS. Is this commonly seen by anyone else? I am convinced this is a problems with these remote servers. But the idea of putting the onus on them to fix things is unpalatable to my employeer. Can anyone else verify seeing this in there logs, or offer suggestions on how to build my case?
