SBS 2011: Exchange 2010 server on email blacklist
Hi All,
A customer recently rang to say their emails arent all being sent. On investigation they are on an emai lblacklist.
I've put a request in to have it removed. But need help to find out why?
Also, how do I find out how many emails have been sent today?
The Queue only has 15 emails waiting, which are all because of the blacklist.
Any suggestions?

at the moment there is no ports blocked on the lan and the exchange server accepts from all sources.
Open relay isnt enabled.

Thanks for the tips.
Server passed the open relay checks and i've restricted port 25 to the SMTP server.
Are there any checks I can do on the server. As they were only on one blacklist i'm starting to think they havent done anything to be on there.

They noticed some email stopped being sent around 2pm BST and that they were on a blacklist around 4pm. They applied to be removed around 6pm and were removed soon after.
All emails are working now, but I was hoping to find out how/why they got on the list in the first place.
