Thunderbird times out when trying to connect to my email server to get new emails. Sending works fine.

Posted

Updated Thunderbird about 2 weeks ago and emails got glitchy for about a day. Forums said "wait for it to catch up," and apparently it did. Have been sending and receiving new emails just fine since then.

3/22/19 10 PM was the last email I have received from the server to Thunderbird, 3 days ago. When I open or check for new emails, it returns the message "connection to server mail.xxx.com timed out." I have increased the amount of time that it will use before giving that message (no change) and consulted my email company (all settings are correct). I can see my emails on the webmail at the server so I know what I should be getting.

I am having NO issues with sending emails from Thunderbird. Several test emails have been delivered normally with absolutely no issues -- only times out when trying to get incoming emails. So today I updated to the latest version of Thunderbird, 60.6.0, and no change to my situation after restarting the program.

I can hope that it is going to be similar to the last update and "will catch up," but I am having some doubts. Sending still works fine.

Is this a known thing that is being addressed already? Any other suggestions?

After trying several different settings over 2 weeks to try to get my emails off the server to Thunderbird (and hoping it might fix itself, which it didn't), this morning we had a breakthrough. I disabled the "smart firewall" on the Norton Internet Security program for 15 minutes and tried to connect Thunderbird. It asked for a password and on the third try I entered the right one (this is the problem with passwords!) and in came 170 emails. So at least, I figured, I could check my emails by turning off the firewall a few times a day for a short time -- but when the 15 minutes expired, Thunderbird is still able to check for incoming emails.... Problem solved, but I'm not quite sure exactly how... but it was a Norton vs Thunderbird issue, we at least know that.

1. What mail provider is it? 2. What is the server name?

Have you tried disabling your anti virus email scanning component. Sounds like you might have an issue there as you can send it is unlikely to be your firewall, unless it is port blocking not application blocking.

Email server is called isp.com I haven't messed with any of the antivirus (Norton) stuff, because it was working just fine and nothing was changed to cause the hang up. [Warning: middle-aged housewife who isn't very tech savvy ... expect dumb questions.]

I don't see anything in the "spam filter" place for incoming or outgoing emails that is out of the norm (nothing in there for outgoing; only junk emails in the incoming box). I tried to check Norton for antivirus email blocking -- it does have a place with a check box (which is/was checked) to "protect against timeouts" -- for when it is scanning a large attachment, etc.

I called the isp.com people today and after confirming all the settings were right, they just said it wasn't on their end, probably something is changed with the Thunderbird update I did 2 weeks ago. In spite of the fact that it worked OK for most of the time between that and last Friday.

What everyone forgets is Nortons calls home every day, so it changes daily. Those "suddenly is does not work" issues are most often a problem with the anti virus.

Basically start by disabling Norton's email scanner. It does not work with most email accounts anyway. As ISP uses SSL in it's connections the Norton mail scanner will not work on the best day.

Thank you. I have changed the settings yesterday for isp to those you have linked (to pop.gmail.com) but it didn't help -- and when I called customer service, they confirmed that what I have had it set at all along (mail.isp.com) is the correct setting -- despite their own website saying otherwise. Maybe I should call them back tomorrow and point this out. I have no add-ons in Thunderbird (deleted the one I did have yesterday).

So for now I have turned off the Norton email antivirus scan (Norton complaining loudly that this is not good), and changed the incoming email server setting to pop.gmail.com in Thunderbird. "Connected to pop.gmail.com ..." and then it waits quite a while before the time out message, "Connection to server pop.gmail.com timed out." I think I'll try turning off the computer and restarting with these changes next to see if that makes a difference.

Using the pop.gmail.com setting made it ask for a password, which it then said "user name and password are not accepted."

Nortons does a great job of messing with all mail programs. It does tend to leave Outlook alone. Perhaps they actually test against that one. But the norton Firewall, the Sonar and the mail scanner are all problematical.

Every minor bump in the Thunderbird version from the 6 weekly updates leads, or often leads, to the program being blocked from accessing the internet by the firewall.

The sonar makes the new account wizard fail in 90% of cases and the email scanner only works in non SSL/TLS protected email accounts. Again almost all mail accounts.

So, all in all, a great product if all you do is surf the web using a web browser. I constant maintenance and tweaking point if you actually use programs that are not a browser. I suggest you contact the Norton Tech people and ask them what is wrong with Nortons.
