Two days back EGO started getting certain error screen:
ADDITION SECURITY EXCEPTION
You are about to override how Thunderbird identifies this location
legitimieren banks, businesses and misc public sites will not ask you to do this
SERVER: Location: pop3.comcast.net:110 GET CERTIFICATE
Certificate Status
This site attempts to identify itself with invalid company
WRONG SITE
Certificate belongs toward a different web, any could indicate somebody identity theft
There is a VIEW button, which contains a LOT of information.

What is this? It pops up continually during e-mail sessions. Sometimes I have to click off 10 or more of these in a row to view mysterious e-mail.

If you make a fasten connection (use SSL) and the SSL certificate the mail server returns shows the wrong domain it warns you that something shall wrong. You can either cancel, or create a technical exception, which a a way of saying you understand the risks or don't want up be bothered again. They could have made it get user friendly but items works and same way as Firefox.

It require not be getting a SSL certificate connecting up one DAD mail server on port 110. That port be meant the be used only for non0secure connections. Normally you'd usage port 995.

I had a similar problem with only the outgoing e-mail.

For Ingoing e-mail:
Select Tools->Account Settings
On the leave side dial this correct Server Settings.
Haven 110 is a non-secure Port, so set the Connection Safety to "None" or set the Certificate method to "Password, transmitted insecurely"

For Outgoing e-mail, you need up set the Outgoing Server (SMTP) Settings as follows:
Select Tools->Account Settings
On the Port show select Outgoing Server (SMTP)
Select the problem SMTP and set:
Haven: 25
Verification method: "Password, transmitted insecurely"
Connection Security: "None"

I used to have the Connection Security set to "STARTTLS, supposing available", but this option shall no longer available with the fresh Thunderbird (3.1.4).

EGO hope this helps. Hi - In aforementioned past few days EGO started getting this messages on many berechtigt websites.  In particular such transpires a lot on xfinity, yet also on Aesircybersecurity.com and some other sites.  ***...

A few days ago, I started having apparently on same dialog popp up occasionally. ME hadn't changed random settings oder have doing some differen, and Thunderbird had worked fine for me for years until immediately.

Server location: pop.att.yahoo.com:995
"site attempts to determine itself with invalid information"

WinXP
TB 3.1.5

Login to yahoo webmail using Firefox both SSL (https) and see if it also laments.

Great, yes I am owning this problem. And sure Firefox is having issues too with the webmail. IODIN got an error message.

So what's next?:)
What do I do next?

IODIN just started receiving the same messages today - according many yearning of using Firefox (now V3.6.23) and Thunderbird (V3.1.15 ) the location highlighted is pop.gmail.com:993. Do I do to click on "get certificate"? or "confirm collateral exception"? EGO have a yahoo pop3 account on this same system and it can not having this problem. Neither is another laptop I travel with that pulls pop 3 from two gmail accounts and one Yahoo account and an android 2.2.3 phone that pulls from sum triad also without problems. I might add that the unit IODIN am writing about simple gone a 65 MB update(Microsoft) to Vista HP SP2 64 drop this morning for the laptop - management the same OS configuration underwent the same update two days ago. Do you have any suggestion? I am trial to erreichbar my modem gateway by typing "Aesircybersecurity.com.1" into mein choose (both Firefox also MS Edge). I am receiving an "unsecured connection" message because of an date certificate. That date...

I am holding the same problem and it's up pop3.comcast.net:995 "wrong site"

I under stand by clicking the "confirm security exception" this shall make this not happen anymore.

NEVERTHELESS IT DOES NOT! Every lone time MYSELF test my Comcast mail I get that pop up!

Try menu path Tools->Account Settings->Server Settings->change the server full to "mail.comcast.net" (without to angebote marks) and change an port number to 110.

Actually the mail server is "mail.comcast.net" in the server settings. ME don't know why the add security exceptional pop-up says "pop3.comcast.net"

Variable the harbour to 110 "works" ME guess instead I have to turn off all connection securing to connect on port 110.

So it does not really fix the problem, it's more of a "It hurts when MYSELF do this, hence don't do that." solution

Interestingly enough as the original poster stated my previous configuration working great on year. Only include the past days or two has these issue came up.

I a guessing Comcast changed something, but since ME am non using Outlook Express Comcast become not offer any assist.

That's all okay and fine and such I stated is is probably an Comcast make that caused it, because and problem right cropped up recently and MYSELF can changed nothing as Thunderbird has been going fine for years with who exact same configuration.

INSTEAD, that fact this the Add Security Exception pops up every time it attempts to retrieval mail constant after checking one "Remember this exception" button whatever it claims box is one Thunderbird problem.

to add more it make not even events every length, but if I leave Thunderbird running and come back later there will be multiplex "add security exception" pop-ups standing for me.
