Cannot send mail - have I corrupted Mail?
I have two POP accounts. I've been unable to send mail via the main account for about 2 weeks (though I can receive).
Mail says: "Cannot send message using server xxx.xxxxx.net" And "The server response was: 5.7.1 <recipient@xxxx.com>: Recipient address rejected: Access denied"
The other POP account, provided by my ISP, functions normally. My ISP says there has been no change in their policy regarding third parties.
I've made all the usual checks - disconnected/reconnected the router, tried switching from port 25 to 465 and 587, checked Connection Doctor - which gives 4 green lights, and had my ISP confirm the line is fine, and made sure the network port configurations appear in the right order. But the problem persists.
The providers of the problem POP account (who haven't been helpful) said "We often get this kind of issue (Error 500) if some temporary internet files get saved in the computer."
This is very possible in my case as I remember trying to send an email with a large attachment which Mail said it failed to dispatch; and the item didn't appear in the SENT mailbox. However I was told the item had actually arrived at the other end. So I transferred the item from the DRAFTS mailbox to the SENT mailbox.
Have I created some corruption in Mail? Could this be the cause of the problem? How should I put things right?
