Most mail clients will use sendmail rather than SMTP on port 25 (or another port) won't they? As I said my postfix works fine for sending E-Mails from my MUA (mutt) which uses sendmail. I must say that swaks looks handy though and it's available from the Ubuntu repositories so it's very easy for me to install and use. -- Chris Green
