Hi all,
T-mobile are being quite insistent that the problems I have sending emails
with 4 different providers to port 587 whilst on 3G are not at their end.
I believe I already know the answer to this, but can someone from bitfolk
please confirm that you don't block traffic from t-mobile 3G ip addresses on
port 587...?
(Has anyone come across this issue before? Seems like they have some weird
filtering that drops the smtp connection after the STARTTLS - even happens
on other port numbers)
Thanks
Joseph

Hi Joseph,
This may be related to a proxy server that the mobile provider has in place
which sees the traffic coming in and tries to fudge with it. Please let me
know your APN settings and I may be able to suggest a different one to test
with ;)
