Can't Connect to SMTP Server

9027989 shared this problem 15 months ago

Just purchased, so was setting up with Thunderbird. I have my DNS set up to auto configure, and it did properly. Even though it was set up correctly, I'm still not able to send email via this client because it won't let me login to the SMTP server.

"Connected to smtp.mailbox.org"

"Login to server smtp.mailbox.org failed."

Re-enter password and it fails again.

Have you configured Port 587 for sending e-mails via smtp.mailbox.org?

Some providers block or diverge connections to port 25 from their DSL customers as anti SPAM method.
