The only error message you have posed is the AOL server refusing to send mail, yet you say it is working Ok.

So I am guessing you have the wrong SMTP server selecting in the identity (the entry above server settings in account settings. You might need to scroll to see the entry at the bottom of the panel, as the developers are making everything like a web page so just because you don't initially see it does not mean it is not there.

Note this bit well. Trying to reconfigure or fix an existing account in Thunderbird by adding it again is prone to complete failure that can actually make things worse. Please do not do it.

Fundamentally I have no idea what your actual settings are except for this and this

But the server name used for your hosted domain is not what your host told you to use. Which from what you have posted I assume should be mail.Resourcesforchange.com

Please correct both the incoming server and the outgoing server (SMTP) entries in the account settings. WHile you are att it, remove the use of SSL/TLS and replace it with none. Change the incoming port to 143 and the outgoing server port to 587 and again no connection encryption

The new account wizard has picked up something, probably from the MX records in DNS. But it is not what your provider ask you to use. You generally do much better using settings that exactly match what you provider tells you to use.

I apologize for not sending complete information. I have gone back to the server settings for my Resourcesforchange.com email as you suggested, per the ISP:

 Username Your email address
 Password Your email account's password
 Incoming servermail.[your domain name]
 Incoming portsIMAP - 143
 POP - 110
 Outgoing servermail.[your domain name]
 SMTP (outgoing) ports25 (587 or 80 might also work)
 IMAP use port 143

I still get a 'cannot be sent' message. Do you have further suggestions? Thank you

You are talking about sending mail and not supplying the outgoing settings. As sending is the issue, knwing what you use would be most beneficial.

You find them at, I think as the developers just do not like stability of locations, at the bottom of the list of accounts in account settings
