Is passing an email list by POST rather than GET possible?

I am using the following to create an on-the-fly live updating email list for interested users on my site: https://mail.google.com/mail/?view=cm&tf=0&fs=1&to=email@address.com&cc=blah@blah.com,another@one.com&body=test%20email&shva=1

This works great for a few emails and has been the only solution I have found for mailing lists using gmail. Please let me kow if there is a better way to do this. Gmail seems to lack functionality to do this on it's own.

So the problem: I now have close to 500 email addresses which gives me the beautiful error

Request-URI Too Large The requested URL /mail/... is too large to process.

For obvi开发者_JAVA技巧ous reasons. I was wondering if there is a way (or one could be added) to support POST variables in addition to GET variables. I tried a few tests with no luck. Please help me as many people count on it. Thanks!

p.s. it does not have to be pretty, just function correctly

Gmail isn't designed to deal with recipient lists that long. You should look for a dedicated mailing list service - you could even use a private google groups group for it.

Remember, if you have a list that long, you'd better be prepared to deal with unsubscribe requests (unless you want your gmail account disabled :). A proper mailing list service will take care of this for you.
