Based on the "no valid authentication mechanism" message and that
you can send again when you turn off K-9's attempt to authenticate
means that your provider changed their configuration. That you can
now send through them without authentication means that anyone else
can too - including spammers, which could result in their outgoing
mail servers getting blocked at some point.
By the way, you might want to check to see if they support Pop3s/995
and Imaps/993 as straight Pop3/110 Imap/143 are not encrypted data
streams. [hint -- you might want to look for a more technically
astute provider.]
