Well having had issues with Mcafee before , this was another issue that took some research to find out what was going on! A friend asked me to check an email problem he was having. He had 2 computers in his house on the same net connection. The email was hosted by GoDaddy, one pc was recieving email over IMAP fine , the other had been , but one day decided to stop. The connection windows in thunderbird brought up “thunderbird refused connection”. At first I removed the SSL connection for IMAP and changed the port to 143. This still brought up the same error. I make sure I could communicate to the imap server and nothing was blocking it router side through telnet “telnet imap.server.com 143” . This brought back the correct IMAP headers so communication was fine which was even stranger. I then used the netstat command to find out what was listening and commuicating in the background. Bingo, I found Mcafee version of svchost.eve was listening on pop3 port 110. I thought this was strange as there was no pop3 email accounts setup on this computer. I unistalled Macfee Internet Security which was on a trial with the laptop and has been disabled, and straight away this fixed the email problem without even restarting! I would like to big up two awesome sites for when you get a new laptop , Decrapifier to remove all the trial rubbish and toolbars you get with a new computer that manufactures make tiny amounts on from the software producers, but loose twice as much with support calls due to it Ninite automated installer for opensource and freeware software
