SMTP Port 25 Inbound & Outbound


[link to this post]
 
Looking at possibly switching to BT Infinity, however I run my own SMTP server, and so require port 25 open both inbound and outbound. Does BT therefore block or redirect port 25 in either direction?

I also use port SSL port 443 for webmail access. Does BT block this at all inbound?

Thanks,

Paul

According to their broadband usage policy they do not block port 25, 443 or any other inbound or outbound port:

I'm on infinity myself. I don't have an email or web server on my home network to test with but I am able to get an outbound connection on port 25 to a 3rd party smtp server.

A bit more info please? I don't see that on the page linked to, (maybe I'm missing it), and don't really want to follow all the links on it to find it.

Re Port 25 itself, that must be a fairly recent change. I configured someone last year and it was blocked for sending to the third party SMTP. I had to use the alternative port provided there.

Edit - The strikeout is because it didn't occur to me to click the down-arrows on the page. D'oh! The robertcrowther reply referring to the asterisks alerted me.

The link does say: Are any services, content, applications or protocols always blocked on this product? No

But it does have a ** next to to, so there could be some that are blocked.

Unlikely that Port 25 is

Now you are disseminating misinformation yourself, that you accuse others of. What a hypocrite!

But it's posted on a website and according to you could be incomplete or inaccurate. Furthermore, it is in a section devoted to Traffic Management.

Traffic management is not normally understood to refer to SMTP access ports, and the context of the whole page is throughput control.

Stop throwing your toys out the pram. It was you who said you could not read the link, I just pointed out where the OP of the link was talking about.
