sending email with debian

[Keith Barrett]

Hi

I can now receive e-mail using fetchmail and mutt.

Wondering now about sending mail?

I collect mail using smtp.

Wonder what are the most simple options for a beginner?

I have more than one email address and fetchmail is collecting mail from 
them.

Would like to be able to filter mail later but would like to get the sending 
sorted out first.

Thanks all for your patience.
