This is my second time configuring Tbird, but it has been a long time since I did it.

I have watched the video at least 10 times.

Last night I attempeted to configure 5 times but nothing worked. Today I finally got it configure but....

My BV account is aguycanbeachhostel.com with a sub account aguycanbeach.com The second has 3 email addresses; the first - general mail is set up in Tbird. When I go to set up the second I get the following error...

A mail or newsgroup account with the same user name and server name already exists. Click back and enter a different server name.

Why am I getting this? What am I doing wrong?

I have done this in the past for multiple emails with no problem.
