Comments on: Norton Internet Security May Be Disabling E-Mail http://www.tech-evangelist.com/2008/10/17/nav-thunderbird/ Technical Articles, Musings and Opinions from Tech-Evangelist Sun, 29 Jan 2012 19:09:23 +0000 hourly 1 http://wordpress.org/?v= By: Vincent http://www.tech-evangelist.com/2008/10/17/nav-thunderbird/comment-page-1/#comment-23772 Vincent Fri, 04 Nov 2011 17:03:05 +0000 http://www.tech-evangelist.com/?p=252#comment-23772 I recently upgraded to Vista Home Premium 64-bit from Home Premium 32-bit, and had to reinstall all my applications (over 70). Since then, I have been recently experiencing when I come to my computer in the morning that Thunderbird is no longer able to retireive my email, and just sits there trying to connect to my email srver (Earthlink). I rebooted in the past and Thuderbird worked again, but this has become a pain, so I did some research online the next time this happened, and came into this support page and read about Norton Internet Security (NIS) being the culprit in the past, but that they had not seen this with the latest NIS version. But I am running the very latest version of NIS 2012 with all the updates. So, it made sense that NISt had received some updates during the night and was disabling Thunderbird. I first checked to verify that Earthink email was working, I went directly to the online Earthlink web site that allows you to retrieve email thru a browser (webmail.earthlink.net), and it was working just fine! This meant the culprti was almost for sure NIS. So, I started turning off different settings within NIS, and finally found that turning off the email anti-virus checking made Thuderbird work again, ALL without rebooting! I made sure with each test to terminate Thunderbird after changing each of the settings in NIS, and restarted Thunderbird to see if each change made it work, so I think this method proved what is going on and what to do. As a result of turning off Email Anti-Virus Scan (Settings, Network, Message Protection), I got a red NIS error indicator to show up. So, after I checked Thunderbnird and downloaded my latest email, I told NIS to Fix it, and NIS all went back to normal. And Thunderbird continued to work and download email after "Fix'ing" NIS. So, I found that NIS IS the culprit, and what to do to get Thunderbird to work again (to connect to the POP3 email server and receive emails), all WITHOUT rebooting! In addition, there is another help site that says you should check to see if you incoimg POP3 port (port 110) is working, via a Dos cannd under Windows. This command is suppose to be "telnet", but Windows does not recognize this command at all, so this info is totally bogus.

If e-mail still does not work, it is probably not a Norton problem. The Norton problem that we found occurs after a definitions update. We have not seen this problem with the current version of Norton Internet Security. Call your ISP's tech support. You likely are having a problem connecting to their mail server. Hi Virginia

Follow the instructions and reboot your PC. If e-mail still does not work, it is probably not a Norton problem. The Norton problem that we found occurs after a definitions update.

We have not seen this problem with the current version of Norton Internet Security.

Call your ISP’s tech support. You likely are having a problem connecting to their mail server.

I re-booted my computer and this allowed one and only one message to be sent. I tried uninstalling and re-installing Thunderbird to no avail. Uninstalling the Norton software cured the problem. A similar problem occured using Windows Mail but with this both incoming and outgoing mail was blocked. The problem with Windows Mail was also resolved when the Norton program had been uninstalled.
