Kevin,

Did you get this resolved?

We cannot recieve certain messages from one client, some go through and some don’t, the ones that don’t, fail with the 552 error.

We thought we fixed it by increasing the Line length on the SMTP settings on the firewall, it was suggested that the originating email had had character strings with no spaces. Change the Line length setting from 1000 to 8000 on the receiving firewall.

Recently they have started getting the same failures sending to us again, we have increased the line length again with no effect.

Thanks in advance if you have any ideas.

Scott

Kevin,

Looks like the message is getting there and then being rejected. Can you send mail to another person at that domain?

If not then I suspect they are rejecting your email as spam. If you’re not aware, mxlogic provides a hosted spam filtering service.

A couple thoughts that may be applicable if this is a new internet mail domain or notes server.

Confirm on the basics tab of the server config document that the “fully qualified Internet host name” field is correct. This is what is sent for elho or helo ( I don’t remember which is the correct term anymore)

Confirm that reverse dns is set up for your mail server.

Both of these can cause your email to be blocked as spam.

Good luck
