ThunderBird Email Problems with Windows 8

Unable to send Email Messages

If you are unable to send email messages from your Thunderbird account, there can be two reasons behind this:

• Inappropriate Thunderbird Settings
• Blocked Port 25 by ISP (Internet Service Provider)

To resolve this issue:

Ensure that Thunderbird Settings are appropriately configured

• Incoming mail server (POP3/IMAP server): mail.yourdomain.com
• Outgoing mail server (SMTP server): mail.yourdomain.com
• Username: the full e-mail address like [email protected]
• SMTP authentication must be enabled for the login to be successful.

• Try using alternative TCP port 2525 for SMTP Server.
