IP Ban By Message Lab, Suspect of Hosting SPAM Mail Server
Posted on 2007-03-23
I got a big problem. Our company emails are outsource to 3rd party that is providing us POP3 accounts. Recently, Internet IP address is listed in 1 of the hundreds Public SPAM Database and some of the email got bounce back with Mail failure indicating the email send my company staff were spam.
Despite I delisted my company IP from it, those email is still bounce by Message Labs. Is there anyway to prevent internet IP being listed as SPAM IP? My company always got alot of outside people coming and going out using our internet to send out email. Is there any software or hardware to monitor such issue and prevent them from happening? I'm grateful for any valuable help or suggestion, you expert can provide.
