I'm using hMailServer 5.3.3, with only POP3 and POP3S protocols enabled. I can telnet to the server just fine, but I can't seem to receive emails from anywhere (gmail, outlook)
I don't get any Mail Delivery msgs when sending, nor does the server log any connections trying to be made. The ports (110 and 995) are open (I've checked on online port scanner).
When I run the server's diagnostics tool, it prints the following:
Test: Collect server details hMailServer version: hMailServer 5.3.3-B1879 Database type: MSSQL
Test: Test IPv6 IPv6 support is available in operating system.
Test: Test outbound port SMTP relayer is in use. Trying to connect to host ... Trying to connect to TCP/IP address Trying to connect to TCP/IP address on port 25.
ERROR: It was not possible to connect.
Test: Test MX records Trying to resolve MX records for ...
ERROR: MX records for domain could not be resolved
Test: Test local connect Connecting to TCP/IP address in MX records for local domain domain ... ERROR: MX records for local domain could not be resolved
If I enable the SMTP server, the diagnostic prints the same thing.
NOTE: I don't have a MX record set. Do I need it?
NOTE: When I try to send an email from a different local server (POP3+SMTP) to my gmail account, the gmail account doesn't receive the mail.
