I have an email recipient who is not receiving emails I have sent. Their IT dept has checked their junk mail and rejected email logs and have no record of the emails and my Windows Live mail does not have any rejected records.

Is it possible that Ad-Aware is stopping me sending to this particular account?

My ISP is BT and I'm using McAfee Security Centre (BT NetProtect Plus). In Windows Live Mail I've registered the addressees domain as OK.

Thanks

I don't think AE Free or Plus would block outgoing email, rather they protect incoming malware from making changes to your system. AE Pro has network protection which blocks malicious IPs, but those are usually known web sites; you'd also see an AE notification and a list of blocked IPs on the Ad-Watch screen.

My guess would be a firewall setting or a problem with your email server or ISP.
