Connection refused due to abuse. - NDR
Hi guys,
I've been getting this NDR when sending out an email to a particular address. Checked the RBL's and were not listed. Email sending and receiving are ok except for this one. Dunno what's up.
550 5.7.1 <user@company.com>... H:MXB [xxx.xxx.xxx.xxx] Connection refused due to abuse. Please contact your E-mail provider.
Any ideas?
TIA.

Some mail servers won't accept email from DSL/cable ranges. Stops the botnet spam. Annoying if you run your own mail server however.
It may just be that somebody else on your ISP has spammed that server before and the administrators have blocked the entire range. -

You could test, by changing your outgoing mail server to your ISP's SMTP server and see if it works. If it does then that should give you an answer as to what may be happening.
