Postfix help

ok now tuurns out host is blocking port 25 so where in virtualmin can i change it to something else so mail gets through and outside servers can reach it

Hi,

You can use port “587” which is an alternate port to 25. It’s setup in Virtualmin by default, so there is not configuration changes needed on the server.

You can use port 587 for your users to deliver mail to be sent outside. But if you want to receive email from the outside for your users, you must use port 25. If your hoster does not open that port for you, your server will not be able to receive email for your users.

Locutus,

I think his issue is at the ISP level. So he can safely use port 587 to get around ISP’s who are now blocking port 25 communication.

Because he’ll be using IMAP or POP to download messages, he just needs 587 to handle the sending of email through his ISP.

Again, I don’t think his server provider is blocking port 25, this would be insane and I’d instruct him to switch providers if this was the case.

This is sorted it turns out they were blocking port 25 but this has now been opened up for me so I can receive emails.

But as far as I understood he’s trying to receive a mail from the outside on his server. And that only works on port 25, since other servers always try to deliver mail via port 25. There’s no way to tell them to use a different port for your server.

Locutus,

You’re right, my bad.
