smtp server

[timinator]

Hi, we host our own mail server on a Fedora box. We would like for our field people using there smart phones to be able to send and receive mail. Receiving is no problem but sending creates problems with relaying and port assignments. Is there any way sendmail can be configured to allow these mobile phone users (AT&T, Verizon) to send mail through our server?

Thanks
Tim

how you configured your smtp, is it pull then send.
are you able to use it on your any mail client and see, if you are able to send the mail, using the smtp server.
