Hello,
I have installed Thunderbird and made 6 email accounts. I can receive emails, but when I want to reply, or to send an email from one of the accounts, I have the message: Delivering email.
After a while the next message appears: "An error occurred while sending mail. The mail server responded: heartofgold.neobee.net
(neobee.net is my ISP). Unexpected failure, please try later - closing connection.. Please check the message and try again."
I had a lot of pain coming to this point, because, before this, I could not send an email at all(got message that connection to my smtp was interrupted in the middle of sending).
Any help with this problem, PLEASE!
Thanks,
Nenad
