Thunderbird checking mail server capabilities

Thunderbird checking mail server capabilities

Squirrelmail configuration

I used the Mailbox button to build the email address [email protected], but I’m having trouble configuring the account in Thunderbird. It doesn’t find any configuration on its own, and I tried all of the options and failed. Exim does not have any issues because the forwarding service works (I hope). So, what does a new email account’s default configuration look like?
It’s really not running.
This information is obtained by probing the server with Thunderbird:
Auth: Normal Password, IMAP, hostname: domain.info, port: 143, SSL: STARTTLS, hostname: domain.info
SSL: None, Auth: Normal Password, SMTP, hostname: domain.info, Port: 25, SSL: None
When I click “Over,” however, I get the following message: “Configuration could not be checked – is the username or password incorrect?”
I’ve done everything there is to do. I deleted and recreated the account, changed the password, didn’t change the password, and used usernames with and without the @domain… Is there anything else I need to do to unlock the account? Debian GNU/Linux 7.5 is what I’m running (wheezy)
It appears to be a flaw in Thunderbird’s setup wizard: https://bugzilla.mozilla.org/show bug.cgi?id=53880… – but actual Thunderbird mail delivery is unaffected.
Is there a way to bypass the verification process?

Fix your imap server wants to alert you to the following

A bug in the “ESET Internet Security” (or “Smart Security”) firewall/antivirus software will cause the Mozilla Thunderbird email program to stop retrieving mail after upgrading to the new Thunderbird version 78.
If you have ESET installed and Thunderbird simply hangs with the message “checking mail server capabilities,” ESET is almost certainly to blame. There are some posts about it on their forums ([1], [2]), and it has nothing to do with our servers — Thunderbird 78, in general, fits well with our servers.

Smtp authentication primer using wireshark

Thunderbird accomplishes this in a unique way. I’m guessing it’s attempting to attach a list of subdomains to the right side of your e-mail address. Is this accurate? If that’s the case, does anybody have any documentation or a list of subdomains that it tries in order?
If we can’t find a configuration file, we use heuristics to try to guess the configuration. We test imap.domain, pop.domain, pop3.domain, smtp.domain, and mail.domain, using the same 2-3 ports for each. We examine whether SSL is usable, as well as the server’s authentication algorithms, which are mentioned in the CAPABILITIES section.
Although it was once popular to run imap, pop3/pop4, and smtp services on separate hosts (or at least have separate DNS records), the current trend is to run everything on a single mail host, which Thunderbird is attempting and succeeding at.

Configuring sage 50 to work with a webmail account

This seems to be a concern for me as well. Thunderbird stopped uploading new emails for all three of my email accounts. Mailwasher, on the other hand, is still operational. My work email started working after I disabled email scanning in general, but not my Gmail or Verizon accounts.

Since last night’s download of detection engine updates 22403 through 22405, I’ve been having issues with both POP3 and IMAP. The only option I’ve found is to turn off the POP3 scanner and the IMAP scanner. Windows 10 Thunderbird 78.5.0
