send e-mail without use sendmail

[Dario Lesca <d lesca solinos it>]

I'm looking for a line command utility (MTA) which send an email direct
to a SMTP external server.

if I use: "echo bye|mutt -s bye user dom it"

the message is send to local sendmail, then sendmail send it to mx
record dom.it, but dom.it refuse me for security and anti-spam reason.

I'm looking for a command which send my message direct to my provider,
like evolution or Thunderbird do.

Is this possible do that with fetchmail?

Or I must use another command?
how to? (I'm not a email guru)

Many thanks
