When sending to .AOL addresses I receive Mail Failure Notice of AOL will not accept delivery of this message 521 5.2.1.
I am a Century Link user. Century Link says not their fault that AOL will not accept delivery. Blame it on AOL. When using the Century Link webmail program as opposed to Thunderbird the emails amazingly make it through. I am the Secretary of a group and cannot be using two email programs and having messages stored in two different places. This problem just started in the past few days - in the past emails from Thunderbird went through just fine.

Webmail infrastructure is independent from POP/IMAP/SMTP servers. Therefore, if webmail works, this isn't an indication that there are no other problems.
Not that it really helps, but you're not alone. See https://support.mozilla.org/en-US/questions/1174317
This is not a Thunderbird problem. You should keep complaining to Centurylink.
