I just e-mailed the developer. I'm having 2 issues:

1) E-mail forwarding: I get a 550 error saying that my sender doesn't have a domain. That's easy enough to check - yes, I have a domain on my sender's e-mail. I've never gotten e-mail forwarding to work and would love to see it happen - e-mail seems to get checked fine, but can't be sent!

2) ical integration, as mentioned before, isn't working under the current version of isms.

I'm recommending this product b/c it does send SMS messages.

Note to the author - I saw your nice post from last year - I understand it's a hobby and you don't have the time to handle 99 e-mails/day, but your FAQ is down and 2.1 doesn't even come with docs! If you're charging for the product, it should work as stated - and if it's user error, that might be because the app isn't intuitive - give us some docs and the FAQ back please so we can leave you to new projectts!
