Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

You don't *need* DNS if it's not already there. Just put an entry to otherpc.domain.com in /etc/hosts and then any mail addressed to that domain will, on most default systems, be sent to that IP address. You'll then just need a mail server on the other end configured to recieve that specific domain.
From what I gather, you've one server - your mail server - from which you send mail. Right? And you say you're hoping to 'receive' email on a PC which SSHs into the server. Right?
Take a step back for a minute. Your sending server - let's call this Server A - will need to 'speak' to the receiving Server B ('PC' as you've called it in this case) over SMTP. The receiving server will then say "hey, thanks - got the message" and depending on what rules you've set up, it'll either be delivered locally, or processed further.
Right now, you're saying the receiving server is able to SSH to the sending server. Unless, however, you're doing something exotic like using SSH to set up a reverse tunnel, triggering Server A to flush its mail queue via an unbound port back to the SMTP listener on Server B (which is possible, but ridiculous), forget about SSH.
It's hard to work out what you mean by 'relay[ing] on the mailserver to send the email'... can Server A and B see each other 24x7? If you set a hostname to loopback (ie 127.0.0.1 lenny.local in /etc/hosts, for example), you can then set up aliases as address:user in your Postfix configuration on box A and simply connect via, I don't know, whatever client you like on the PC - 'Server B' - to retrieve the mail.
Flesh out your set-up a little more and me wight be able to help you better.
