Topic: cannot receive external email

[tmiller281]

I have installed and configured sme 7.4 and can send and receive email internally but cannot receive mail from external sources. I am able to send after configuring the smtp authentication so that is not a problem.

I have configured my firewall to allow in pop3, imap, https and telnet traffic to my sme server. I am able to connect from the outside world to webmail and can telnet into port 110 sucessfully using the fqdn of my email server.

I am at a loss as to why emails are not being accepted.

any suggestions?
thanks

If you are running a mail server on your SME, then you need to configure your firewall to open/forward port 25 to SME.

You might also check that your ISP is not blocking port 25.

Do a check at grc.com to see what ports are open.

If you have DNS for your domain configured correctly, email is delivered to your server via smtp (port 25). If you don't have port 25 forwarded to your server, you won't receive any email.

Thanks for the info.
I talked to my ISP and they are blocking port 25. They are using port 465 for their own systems.

Anyone have any experience with services such as dyndns.com mailhop relay? Thinking that maybe I can have them host my dns records and have them deliver my mail to an alternate port, that is if i can change the default port on the sme server.

Get them to unblock it or consider changing ISPs.

You will have less success battling spam if your mail is relayed via a mailhop relay.

You don't need to change the default port, you can portforward from 465 to localhost:25.

Not sure I understand how this will work. If my ISP is blocking incoming port 25, don't I need some kind of redirect service to send my incoming mail to another port?

Yes, but you do not need to change the default port for smtp on SME server. You can leave qpsmtpd listening to port 25, have a redirect service delivering to port 465, and add a port forward to connect port 465 to port 25 on SME server.

ok, I understand what you are saying. Need to find a reasonably priced service to redirect my incoming emails to port 465

As stated earlier, you would be better off changing your ISP (either by getting them to change their settings for you, or by switching to a different ISP, or different plan). You lose one of your best ant-spam tools (RBL) if you use a redirect service.
