Good Morning,

Our server had an issue over the weekend where it was spammed, we ended up being blacklisted by Sorbs.

This was resolved yesterday morning and blacklist was removed (we contacted sorbs), I have completed several Blacklist checks, and the mail server is all clear and was from midday yesterday.

However I am still unable to send to microsoft server. My question is: when will we be able to send to microsoft servers again. (How long is the blacklist information cached for).

A response would be much appreciated.

Regards,

Tom.
