I can blast mail out of here to anywhere from any of my machines using postfix. If I try to send through an ISP I get nasty "we don't relay" messages (that is, you cannot send through one ISP and have the MX record relayed to the SMTP program at another, for the initial transmission). For this reason, I cannot respond directly to the expert list from work (because I cannot make it originate at my private account. So what you can do, easily, is set your mail transmission program (like Kmail) to send from sendamil then go about your business of dialing (sendmail in this case is a symlink to postfix) with your various accounts and transmit the mail. you do NOT need to use the SMTP programs at the ISPs for your initial transmission, your linux box will do. Now if you really want to wow 'em, configure fetchmail to gather the mail from all six ISPs with just one dialing, or for even more fun, use postfix as it was intended, give it a name of the form companyname.yi.org and get in touch with yi.org to relay MX records and run their little script to update your IP address every 5 minutes and you are ON the internet as your own station, regardless of connection, and everything sent to companyname.yi.org is received and spooled and can be queried from other internet locations for registered users (as POP users on your box) or from the box or anything networked to it. And to configure postfix, get it running, then make sure you install webmin-0.80-4mdk.noarch.rpm and use it to configure postfix. It took me 12 minutes. If you have any questions, email me privately since I want to write a section on postfix and need to know about problems encountered (a 12-minute install is nothing to write about). I'll be happy to help. Civileme
