sendmail: how to send mail from my yahoo e-mail address
Slackware 10.1.0 on an eth0 dhcp connection to the ISP (i.e. dynamic IP address).
I have my system set up to receive and filter mail ok, using fetchmail and procmail. I read my mail with mutt.
In order to send mail I use mutt. I have defined myself as a trusted user so that I can change the "From:" address without warning headers being included in the outgoing mail.
This is not kosher - I wish to send my e-mail to my smtp address on yahoo and have yahoo send it normally.
With Thunderbird, of course, this is not a problem - but I no longer wish to use Tb - it is too bloated and slow - Mutt is better, once you have it configured right.
The problem is asking the right question to get the right answer - in short I wish to replace Thunderbird sending mail by mutt and sendmail sending mail.
I do NOT wish my machine itself to act as a SMTP server (I hope I have expressed myself correctly there) - I wish to use Yahoo to send my mail. I want sendmail to get my mail to yahoo so that it can send it - with my genuine yahoo address.
