I would like to be able to setup a reminder 'service' for myself so that I can schedule emails or text messages to be sent to my handheld when I can't get to an ssh client.

Here's my scenario:

It's now noon. I need to give myself a reminder in four hours to pickup milk on the way home from work.

I would like to be able to email a special account I have setup that will dump all messages that are not from "me", and that will take the subject line as a command, and the body as the message.

For example, the following email could be sent:

Subject: at 16:00 txtmobile
Body: pickup milk

I'd like to grab that mail, pull the subject apart and hand it to a script that will set an at job for 16:00 that will call my txtmobile script with the body contents as the SMS message.

That way I can send myself reminders from work or whereever if I can't get to the calendar function on my phone.

Two questions. First, is it possible? Second, is there a better way to do it?

Something like this in .procmailrc:

* ^From: me@example.com
* ^To: mycalendarservice@example.com
| somescript.pl

somescript.pl will get the mail on standard input, so you could parse it apart like this:

while (<>) {
        /^Subject: (.*)/ and $cmd = $1;
        /^./ and $body .= $_;
}
chmod $cmd;
open(OUT, "| $cmd") or die;
print OUT $body;
close OUT;

Be sure to make this safe from abuse.

(I'll answer the second question.) You should consider one of the many web services that will do this for you.

Remember the Milk, for example, will do what you describe and a lot more.

maybe I missed it in the tour, but I don't see where I could access it via an email or txt message to send me a reminder later –  warren Aug 19 '09 at 22:52
    
See the paragraph with the title "Add tasks wherever you are." –  Richard Hoskins Aug 20 '09 at 1:19
    
yep, there it is - right in front of me and I didn't see it still wondering how I'd do it myself, though :) –  warren Aug 20 '09 at 11:55
