My customer says nobody can send email to them as of this morning.  This has been working fine for 6 months.  Now when I sent a test email to them from my gmail account I get this:
Technical details of permanent failure:
PERM_FAILURE: Google tried to deliver your message, but it was rejected by the recipient domain. We recommend contacting the other email provider for further information about the cause of this error. The error that the other server returned was: 550 550 5.7.1 74.125.44.28 has been blocked by BlackList - blackholes.wirehub.net (state 14).

Any help?

It appears that SBS 2003 ip address has been added to a blacklist, which will block all messages from that server.  I would check your email-filtering server to see if anything has been added to the blacklist.  Most email filters do have a whitelist and you could add the ip address or domain to the safe list.

Hope this helps.

I found the solution myself.  I had previously setup a blacklist connection filtering to a known site.  It's been working fine for a couple of months.  All of a sudden, that same site was listing us as blacklisted.  the bounce message above shows the name of our own filter setup on exchange: blackholes.wirehub.net

To fix it, I opened System Manager, went to Global Settings, right clicked Message Delivery and went to properties.  Connection Filtering tab and removed the rule under Block list service configuration that pointed to blackholes.wirehub.net.  This fixed the problem.  It's possible to think that blacklist site went down?

Don't know but it's fixed...

If your client was on a RBL they would not be able to send some people mail, receiving should not be affected. Possibly if they are on a list the ISP could have suspended their mail but they normally just block outbound.

Can you telnet clientpublicIP 25

Could anyone have changed any settings on the exchange box? Especially under message delivery properties?
