Relaying remote networks

I have postfix working fine but I want to be able to send mail from my
mobile phone. My phone provider doesn't have an SMTP server so I asked them
for the IP range that they assign to mobile phones so that I could configure
postfix to relay from that range of addresses too.

I'm using Postfix 2.0.18 and main.cf I put the line :

mynetworks = 212.129.64.128/27, 10.2.15.64/27

10.2.15.x being the local network and 212.129.64.x being the IP's given to
the mobile phones. However, after doing this, the server won't relay for
either of these two subnet's.

Am I missing something obvious? I'm new to postfix and it worked right from
install until I wanted to do this. I use it with OpenWebmail and have been
for a year with no problems.

TIA,

Matt Lemon.

Try this:
smtpd_recipient_restrictions = permit_mynetworks

But I definitely wouldn't do it this way! I mean: Keep in mind - every
user within that ip range is able to relay mails over your server
without further authentication!!
What about smtp-auth? Is it supported by your mobile phone? Another
possibility could be pop-before-smtp (if pop3 is supported by your
mobile phone).

I appreciate the security concerns but the chances of anyone else on the
same mobile network trying to use my SMTP server are very slim.

Anway, When I add that line to the main.cf file it still refuses to relay.
Before I used to get a message saying that relaying was denied but now it
just hangs.

I'd need to see your main.cf file. It's possible you messed up the
syntax somewhere (postfix can be picky about that.) The smtpd
restrictions line should have already been there I'd have thought...
