Re: Web Server Using Postfix #networking

Good day!

Is the Raspberry Pi the email client or the email server? server

Are you saying that if you configure the email client to use the IP address vs. DNS name, that's the difference?  Or is the issue that one is the Internal IP address and the other is the external IP? If I use the local lan address for the PI the email client (which is on my phone) everything works fine with ports 25 and 110. If I use (, the client doesn't setup.

As far as the dig command, I'm using a windows computer but here is the telnet info: My laptop is connected to my local router:

C:\Users\June>telnet 25
Connecting To NOTHING

Got a connection to port 465
220 ESMTP Postfix (Debian/GNU)
250-SIZE 10240000
250 DSN

Got a connection to port 110
+OK Qpopper (version 4.1.0) at starting.

If I switch to data on my cell I can connect to 25, 465, and 110.
