Spamming is easy when you've access to a mail server.

IMAP is completely separate to SMTP, so there *might* be an SMTP server available to everybody.

Well, your sister could try using your server on whatever port you want to use, if you've got network access without the same restrictions. She could sign up for a proper mail service provider, many offer other-than port 25 connections for people in her position. e.g. <http://fastmail.fm/> used to offer such a feature. That's probably easier, and safer than exposing your network. Whatever route you take, your sister configures her mail program to use the address and port she wants to. If you're providing a non-port 25 SMTP server, it's up to you to add some port forwarding in your system to connect it through, or run an SMTP server that listens to more than one port at a time (so you can still do your own mail, normally). -- Don't send private replies to my address, the mailbox is ignored. I read messages from the public lists.
