I didn't find this info anywhere. Long gone along with Eudora, but tech support folk like me that HATE to be defeated keep getting asked to fix this antiquated, but beloved mail client.
So if you have these errors, rejoice, I already suffered for you:
When logging in to NIH email using IMAP: "Could not resync mailbox 5 Login Aborted."
================================================
Convert the box from POP mail to IMAP and back again (or vice versa)
This cleared the mailbox 5 Login aborted message for me.
Then I got the two errors below. (which were also fixed.)
When logging in to NIH email using IMAP: "Server not responding -706"
AND
When logging in to NIH email using IMAP: "Could not get mailbox list. 20. Incorrect password specified. OK"
================================================
Try standard login troubleshooting. Especially ensure that the user id in use is smithj, and not DOMAIN\smithj. Eudora doesn't use the domain prefix.
If that didn't help,
=====================
Delete Junk Mail and move Inbox messages to a different folder. (create one if need be). (May need to use web mail or another client to do this.)
If Eudora starts to work again, you can move the mail back a little at a time until you determine which message is causing the problem.
If that didn't help,
=====================
You may want to try some troubleshooting steps below from a related error, especially engaging your org's Mail support to look at logs at the time of attempted IMAP access.
May or may not be relevant:
==========================
For OS X, make sure that Eudora Settings are set properly for SSL
(In OS 9, the Keychain Access control panel must be loaded and a keychain configured for SSL to work.)
If that didn't help,
=====================
Try disabling SSL (if allowed)
Be sure "user plain text password" in the IMAP panel is selected / enable clear text IMAP access to the server.
If that didn't help,
=====================
Check login name.
You may need NIH\ to precede the username.
You may need the email address to be either
mail.nih.gov or
ninds.nih.gov. Try the alternative. Switch back if no joy.
If that didn't help,
=====================
You may wish to add ":993" behind SMTP or mail server names. (remove it if it dopesn't help.)
If giving servers a port # didn't help,
==========================================
Enable the "Esoteric Settings" plugin (whatever that is!)
You may then wish to increase the "Response from server" time.
If it already is enabled or you've no idea where to find it or how to activate it (who can blame you?)
Ask CIT Mail Server Support to check the IMAP log on the Exchange server at the timestamp the user
attempts to connect.
Is IMAP allowed on the user account?
Explain the symptom to CIT Mail Support.
It may be helpful if you try to send mail to see if that much works.
LDAP lookup test could be useful data for CIT as well.
