Topic: BigPond is blocking of Port 25.

[Crome]

I have had a similar problem with my previous provider. As I too have a dynamic IP, I subscribed to a dynamic DNS provider namely No-IP.com. It is a payed service but I've used it for a few years now and it's great! One of no-ip.com's features is that they can redirect your mails to another port. So when mails are sent to my domain they arrive at no-ip.com (make sure your MX record points to no-ip.com). Then they send your mails to whatever port you'd like (825 for me). Works just fine. Another great benefit is that when my mailserver goes down, my mails are queued at no-ip.com.

And they don't even pay me for this...  

Cheers.

You can however recieve mail on port 25 with mail.MYdomain.xxx, which proves they are not blocking the port.

So how can you send outbound 25 mail with mail.MYdomain.xxx?

SME server allows you to send mail.MYdomain.xxx out using your ISP's domain.

Server-Manager > E-mail > Delegate mail servers  > Address of Internet provider's mail server

Enter your providers smtp (outbound) server name here.

ie.  smtp.ISPdomain.xxx

I my case it is RoadRunner so it looks like this.

smtp-server.xxx.rr.com

Leave the > Delegate mail servers > Address of internal mail server > BLANK.

Hi electro,

The problem here is that we cannot RECEIVE mail... not sending them.
For exemple, if I login with the webmail interface (imp) for a user and send an email to testing@yahoo.com the email is send successfuly (via my ISP's smtp server)
But if I go to yahoo and send an email to webmaster@mysubdomain.dyndns.org I don't receive the email as my ISP's blocking/filtering port 25...

I also made some testing like this: I logging via ssh to my university account. I then try to telnet myself on port 25 (router is set ok, smtp is listeing to) but I get a timeout...

I even tryed to use dyndns.org's mail exchanger set to mysubdomain.dyndns.org; it accepted it, but I can't send an email to someone@mysubdomain.dyndns.org...

I want a solution

thanks for the reply.

EDIT:
@Crome
What do you think about this service? Anyone knows of a free one? Cheaper one? Compared to dyndns.org's? It seems simpler... Anyone having a workaround?

I can't receive emails either to SME 6.0, it was working and then stopped.  I can send email from webmail but not receive anything.  Any ideas?

Just for the interest of readers of this thread see

Telstra clearly says it is only blocking outbound port 25

quote
"The first step is the closure of Port 25 on 13th April 2004.

Will BigPond be blocking both inbound and outbound Port 25?

The blocking will be occurring on outbound only."
