You need to check that you have the correct SMTP settings. Go to Menu > Tools > Accounts, and in the SMTP tab, enter you email provider’s recommended settings.
Can you let us know what the settings in the SMTP tab are after the fix? Host, port and security policy, and whether the server requires authentication.
Thanks Marci. Hopefully any others having difficulty with eastlink, will see this post and duplicate your settings.
BTW, as long as you are using the same Username for POP3 and SMTP, you can choose the option to Use identity credentials. That will use the Username and password in the General Tab of your account settings for both protocols.
This fixed my problem. Thank you so much. I couldn’t send email for a month! I have no idea how the settings got changed. One day it worked, the next day it didn’t. I called my server’s help line. They were NO help.
