Question

I have an iMac, and have a Verizon DSL account (3 email addresses). Recently, my Mac Mail keeps requesting the passwords on my accounts every few minutes, and will not allow me to send messages using Mac Mail (the message says that the outgoing server was rejected. I cannot edit the outgoing server, and the keychain will not save my passwords (the ports are valid). How can I change the outgoing server to send emails, and how can I avoid having Mail request my passwords every 2 minutes? Verizon, as usual, will not provide support to iMacs.

Answer 1

Is there an email saved in your drafts or outbox folder?  I suspect that Mail is continually trying to send it, and each time Google is rejecting the email message.
You can open the message and then delete it from your Outbox folder.  Then try removing all @gmail email addresses from it and seeing whether you can send to the other folks.  I suspect that will work.
With email, if an SMTP server *can* verify email addresses, sometimes it will and it will refuse to send messages.  If a message has to be relayed across servers, no verification is done, and you'll get a bounce if an email address is bad.
