One morning mail on my Mac was working perfectly
At noon I updraded to Mac OS X 10.9 (Mavericks)
Then I could not send mails anymore!
I could read my mails but not send them (though I changed nothing in the configuration) authentification failed!
My SMTP servers (two of these university based) are okay. These are not Gmail things!
So either:
- The new version of Mail is no longer pleased with the servers credentials (though I checked these).
- The new version of Mail sends wrong infomrmation (password) - but since these are still here I am wondering if there is some encoding fancy in the protocol that is not working anymore (yes there are accented characters in these informations!)
What I can I do? Can I downgrade and load an earlier version of the Mail tool?
