Using AT&T 3G network, Time Warner RoadRunner via Airport Express. I can download ok with both wifi and 3G running. But when I try to send, the msg just sits in th Outbox. IPhone 4 with latest OS. I'm using MS Entourage on my iMac as POP server.  I can access mail fine on the phone. Everything works except the Send hangs in the Outbox until I turn WiFi on the phone to OFF. A hung message will send moments after turning the wifi off

    What is your RoadRunner SMTP server set to?  Try using, set to use your RR email address and password as authentication, Use SSL OFF, Server Port 597.

    Port 597 was a typo.  It should be 587.


    My mail account is also on the server and my incoming mail server is set to, but my SMTP server is set to My user name is set to My password is my email password for my roadrunner account.


    I suggest you re-enter your password and try again using as the SMTP server.  If you still can't send, you should contact RoadRunner tech support for help.


    One very long shot is to put as the SMTP server.

    The RoadRunner SMTP server is set as the prime.  Try turning ON the AT&T SMTP Server as an Other SMTP Server, with the mobile RoadRunner server as the prime.

    Thank you for this solution. It's been bugging me for a long time now and now it's fixed - almost...


    By doing this, it always skips the wifi and uses your cellular data plan to send mail. Does anyone know if there is a way to have it actually use the wifi to send mail? You can verify that it is using the cellular data account by turning cellar data off. When you do this, it can't send mail anymore.
