Howdy,

What error are you seeing in the email client when that occurs?

-Eric

mail client says :
Thunder bird is failed to find the setting of this account

any update on it its driving me nuts

Ah, it sounds like you’re saying you’re experiencing a problem with the auto-setup feature in Thunderbird.

What if you manually add in your settings – are you able to get it working in that case?

-Eric

I have the same problem, and it seems to work on and off, mostly not though. Doesn’t matter if I attempt to use auto-configure or manual entry

One quick way of testing an IMAP4 or POP3 server is to download one of the Nagios plugins. https://exchange.nagios.org/directory/Plugins/Network-Protocols/IMAP4-and-POP3. Looks for a plugin that will do an IMAP4 or POP3 login. If the plugin reports success, you know the server is accepting logins, so maybe the client is at fault.

Even though these are called plugins, each is a small, stand-alone program.

Below is an actual transcript, edited.

$ wget 'https://exchange.nagios.org/components/com_mtree/attachment.php?link_id=4093&cf_id=24' Saving to: 'attachment.php?link_id=4093&cf_id=24'

$ mv attachment.php?link_id=4093&cf_id=24 check_imap
$ chmod +x check_imap

Above, I downloaded a Nagios plugin that tests IMAP4 with login. It prints a help message when invoked without arguments.

$ ./check_imap -u -p -s use SSL -H

$ ./check_imap -u bob -p a.b.c.d -H myhost.example.com
OK IMAP Login Successful (Connect: 42.22ms, Login: 25.65ms) | connect=42.22ms login=25.65ms

$ ./check_imap -s -u bob -p a.b.c.d -H myhost.example.com
OK IMAP Login Successful (Connect: 365.18ms, Login: 28.08ms) | connect=365.18ms login=28.08ms

So now we know that the IMAP4 server at myhost.example.com is correctly accepting logins, without SSL (port 143) and with SSL (port 993), for user bob.

Now if bob says his IMAP4 client won’t connect, we know bob needs to check his IMAP4 client’s configuration.

IMAP4 with TLS uses the same port 143, so you should not need to test that separately.

The IMAP4 connection without SSL goes in cleartext, so give user bob a temp password, then change the password when done, just in case anybody could snoop while you were testing.

Note: This particular plugin is written in python, so it should work on any system that has python available.
