Well,
Of course I had to re-enforce the network access policies via AD. The offender happens to be waaaaaay above my pay grade hence whoever configured his/her pc did not add him to a domain. Luckily access to the mail server required that you must authentication hence the damage was not wide spread.
I also had to relay our outgoing traffic via the spam filtering service. Only incoming traffic was being filtered.

Quite true Jimmy. Whenever such a thing happens, it's always good to know what remedial measures have been taken to ensure it doesn't recur.

Sharing such information helps make the 'world a better place', or is it the 'Internet'?

@mash,

What else have you done to ensure another PC on the LAN never subjects you to the same problem?

Already did. It was a pc on the LAN

Address the cause of your blacklisting.

Could be compromised machines on the LAN.

Thank you all,
Forgot to come back. Apparently , I had been blacklisted by several antispam databases. I managed to de-list from several and also used my spare public IPs as I try to delist from the rest. 
I've to say Safaricom guys came in handy to assist me get the de-list faster.

Well, several solutions exist for @mash lists.

1. Build your own server, publish your own MX and use it directly to the world instead of AK
2. Take your services to the cloud - M$, Google, VPS

Access Kenya have certain restrictions on their network which will give you headache if your LAN isn't clean, but that again is the point - clean out your LAN!

Check your network, most likely its blacklisted. They mostly use a funny spam filter site. Check with mxtoolbox.com blacklist.

Anyone working with the above mentioned? For some reason, I cant send mail to any of their hosted domains. Either they've blocked me or they have some issues.
