strange problem...
Hi everybody.
We have a small business... Every computer has windows xp pro inside. We all use outlook as email client... It just works fine, but in the last 3 days every time we try to send email to somebody it comes back saying "mail delivery failure" even if try sending it to myself.
The host said it could be their problem... I think they have linux as server but what could this be? Does anybody have any idea? I think it could be an attack... or something like that... Any help would be apreciated...
Thanks
