I am new to the iphone and have the 32gb 3Gs.
Overall, it is a nice little device.
I am having a problem though that I can not seem to figure out.

I like to go to the "For Sale" section of Craigslist.
In particular, I like the tools area.
Anyways....when I try to post a reply to an ad on Craigslist, the reply
will fail to send and I will get a message window pop up..

+++++++++++++++++++
Cannot Send Mail
The server rejected one of the recipients addresses.
The message has been placed in your Outbox.
++++++++++++++++++++++++++++++++++++

This happens regardless if I am on 3G or Wifi.
I have looked around and if it is happening to everybody, they do not
seem to be talking about it.
I suspect that it may have something to do with the way that the Craigslist
structures its email so as to go through their server before going to the person who posted the ad. I have no idea how to correct this however.

I have tried to go to Craigslist as a regular webpage and I also downloaded Craigsphone (app). The same problem existed both ways.


Can anybody tell me how to correct this?
