Orange ADSL - do they stop/waylay port 25 (SMTP)?

My daughter has Orange ADSL (she was previously with BT) and it
appears she now can't send mail via my authenticated SMTP at
gradwell.net.

Do Orange do something to port 25 or has something got misconfigured
during the change from BT to Orange?

What does:

C:\> telnet address.of.smtp.server 25

tell you?

Most mail servers will announce their identity in the first line; for
instance:
$ telnet smtp.aaisp.net.uk 25
Trying 81.187.81.52...
Connected to smtp.aaisp.net.uk.
Escape character is '^]'.
220 smtp.aaisp.net.uk ESMTP Exim 4.62 Tue, 08 May 2007 16:32:14 +0100

If any transparrent proxying is going on, you will get the same response
from orange's and your server. If they simply block port 25 you'll get
nothing or an error.

I used to be with Orange at home and they *DO* re-route ALL port 25
traffic to their own SMTP servers as I recall.

Orange have taken over Wanadoo, haven't they?

I know Wanadoo blocked port 25 to external non-Wanadoo SMTP servers. You get
a message saying "you must use Wanadoo's SMTP server".

Unofortunately their own SMTP server is only accessible from their own line,
so you can't set up a laptop with a single account that can send/reveive
both from a Wanadoo line (eg at home) and a non-Wanaddoo line (eg at work) -
whichever way you try to do it, they block you.

It's nothing to do with the need to authenticate on sending, because their
server won't even respond if you try to access it from outside their own
connection.

I wonder if Orange have inherited the same customer-unfriendly technology.

Hi,

Back in the day when I used to work for Freeserve they had a port 25
intercept which directed all SMTP traffic via their mail servers, as far
as I know that hasn't changed.

Get them to run another instance of the mail server on port 26 or port
somethingelse.....

I send using authentication via smtp.orange.net - on Virginmedia & sky
broadbands.....

Admittedly, my Orange email account is associated with my mobile, not a
broadband connection.

I find it odd that one lot of their customers can send with
authentication & others cannot.

Any half-way decent mail service will provide an alternate port. Try 587,
the official mail submission port, or ask them. If they support ssl
access, that will default to 465 and solve the problem also.

Good job they don't block NNTP too then since they don't have a news
server any more

Blocking or diverting *outgoing* port 25 connections is a good thing.
It's a way of blocking or controlling spam from the huge number of
infected PCs that generate most spam these days.
