For some reason, I can't send mail.
 

I wish I had more information, but this is a rather mysterious problem. When I first started using Linux, I could send mail just fine in Firefox, Evolution, Mozilla Messenger, whatever. Now, for some reason, whenever I try to send email, nothing happens. No error message, no connection, nothing. I have been using webmail for the time being, but this is rather irritating.

The only thing that I can think of is that I use Gkrellm to notify me of when I have mail. I don't remember if my problem started when I started using Gkrellm or not.

Can anybody think of what the problem might be? :scratch: Thanx.

Are you sending thru your ISP's mail server or your own? If its your own mail server.. well, is it running even?

Hmmm. I guess that might be my problem right there. I honestly hadn't thought about how SMTP works. Perhaps I should should get Sendmail working? Can Thunderbird even use Sendmail?

Thunderbird is an email client.. Sendmail is a MTA.. Thunderbird wouldn't use sendmail directly... as in using a sendmail command, but instead connect and use it as if it was setup to be an smtp server to send mail.. etc.
