Slugmail mail2000

It seems like you're trying to send an email using SlugMail, a free email service. However, I noticed that you mentioned "mail2000" which is not a part of SlugMail's service.

Could you please clarify what you're trying to do? Are you trying to send an email using SlugMail, or are you trying to access an email account with the username "mail2000"? If it's the latter, I'd be happy to help you troubleshoot the issue.
