when i send mail using pine or whatever it will come up as myusername@localhost.localdomain but i'd like it to come up as myusername@something.else (eg softhome.net my pop mail provider or even hotmail.com). I've read a couple of things on masquerading and tried to follow some directions in one but it doesn't seem to work. how do I do it?
it's slackware 9, sendmail, using pine to send my emails, fetchmail to retrieve, just ppp dial up internet on an external modem...

thanks if you can help.

This is probably better done by your mail client than your mail transfer agent (MTA), so leave your sendmail configuration alone (it's a bear to change anyway :-). Most mail clients give you the option of specifying the sender address, which is what will appear on the From: header line in outgoing messages (and also the Reply-To: line). I use Emacs as my mailer, so I can't tell you how to do that in Pine, but look for a Sender Address option.

OTOH, you might mean that you want the address in the message envelope to be myusername@something.else. The envelope is the addresses your MTA use, which can be different from those in the header. Check out sendmail's virtusertable and local-host-names files, both of which should be in /etc/mail. But if you start changing this stuff and your system thinks it's in the domain "localdomain", it
may just cause sendmail to stop working.

I'd go for the mail client configuration, because it's the easiest, and most likely what you need.

cheers for that. I'd already found a simple to follow HOWTO for it and got it sorted. I did initially try to find the option in pine but it didn't seem to be anywhere that I could find...
for future reference, the HOWTO i used is... no wait i don't have the address for it... sorry about that.

Edit .pinerc and change user-domain= tp

user-domain=something.else

Or you can run Pine, hit "M" , then "S", then change "user-domain" to whatever you want.

I hope you will succeed with pine, but I had to reconfigure sendmail when I had the same problem.

actually, it works without any configuration changes:

sendmail -f anyuser@anywhere.com user@domain.com

this option sets the envelope of the sender - man sendmail
