View Full Version : 10.5 server - Blocked domain

I have a blocked domain on our Leopard Server.

Can anyone tell me where to go to lookup the local blacklist please?

Many thanks.

I'm not so sure there is a local blacklist (but to be fair i don't know OSX server). Sounds more to me like the sender is on the SBL lists or something similar

You can do a search here


It's pretty easy to get removed as long as you can work out what is wrong, I got on there once through overzealous use of which is violation of the RFC.
I also found out the other week that alot of "userland" IP's that service providers dish out are automatically on some kind of block list which was rather rude but i can see why the ISP's would want to do it.

Have to ask a quick question because I want to be 100% positive here.

Are you trying to send a message to another location and that is getting bounced back to you, or is someone trying to send mail to that leopard server and it's getting bounced back to them?

One is an issue you can handle (your blacklist) the other is something you may not be able to (Another mail servers blacklist)

Anyways, on 10.5 the local blacklist, if specifically defined, will probably be in /etc/mail/spamassassin/local.cf it may also be due to other factors though, like bayes learning.
