Description: -=SUMMARY=-

pemail is a Perl project I am working on to better learn the Perl language, and to develop my coding skills in general. I don't expect others to find much use out of it, as there are already tools that do its jobs much better, but this is mostly for my own benefit.

pemail allows you to view POP3 email from the command line, with a fairly intuitive interface, much like the UNIX mail(1) command does. pemail also allows you to send email from the same interface, making it pretty much an all in one mail client for the UNIX command line.

pemail requires the Mail::POP3Client and MIME::Lite Perl modules to work.

-=HOW-TO=-

usage:
reading email: pemail -P <server> [-u <username> [-p <password>]]
sending email: pemail -s [address]

Just fill out the information requested and pemail will check your POP3 mailbox, tell you how many messages you have, and then you can do what you like with them.

-=TODO=-

- Hmm... a good thing to try putting in would be forwarding and replying to emails...


I'm putting this code up here for suggestions on features to add and any possible bugs to fix... unfortunatley pemail as a project has stagnated and I haven't done any work on it since Dec. 19, 2000.

More info on pemail can be had at http://www.the-den.org/pemail (when the cable modem is working correctly... sigh). Also of note is that this program was listed in Linux Journal's "Focus on Software" column sometime in late 2000 (don't have the issue handy for an exact month).

    Hi, I am writing a pop3 client in C but I am struck at some points. It would be a great help if you can provide some reference material on pop3 client. My email is sagar_raturi@yahoo.co.in Thanks, Sagar.
