We're using Mail 2.1.3 on a Mac Mini (OS 10.4.11), and having problems with email accounts misbehaving in Mail.
We've been checking 6 accounts (2 gmail, 1 yahoo, 3 from US Cable). Now I've tried to add 2 new gmail accounts (we're losing the USCable accounts in a few days), and started having problems. Even though the settings in both new gmail accounts are correct, they will not send email via the smtp.gmail.com server, and give me the message:
"Cannot send message using the server smtp.gmail.com" and it asks me to send the message using a different server.
Additionally, as I've been trying to troubleshoot this, my 2 formerly working gmail accounts have both started not working. Connection Doctor says the login for one failed, and the smtp for the other "could not connect". Though Connection Doctor says that connection and login to server succeeded for the 2 new gmail accounts, it does not even list the smtp attempts for the new accounts. I've tried deleting and recreating the new email accounts within this main user's version of Mail several times, no success.
All the email accounts are using the POP protocol, and we don't want to change to IMAP (we have multiple users checking the same accounts from different devices). I've verified the settings being correct 2 ways: Setting them up on a different machine (my MacBook running Mail 3.6, OS X 10.5.8) and on the same machine via a newly-made user on the Mac Mini. Both ways can send and receive mail just fine from these new email accounts.
I think something's hopelessly corrupted, and that I need to somehow reinstall the Mail program, or at least get rid of all the accounts and preferences or whatever needs to be deleted, and recreate all the email accounts again. How can I do this, without losing our many messages that we have filed in a number of folders?
Q: how do I do this??
Thanks for any advice, in advance!
