"IP Interface to use" should in most cases be left blank to allow connections from all interfaces, as pointed out in Mercury help.

Hello everyone.

I have installed Mercury/32 as part of the XAMPP package.. the server is connected to an internet domain. I used to be able to receive mails, now I'm not anymore, and I have no idea why. 

I believe my A and MX records are set correctly, however I don't think this is the issue. Let's assume my server IP is 123.456.78.90..  If I send mail to mail@123.456.78.90, it never reaches its destination, same goes if I mail to mail@mydomain.com. Nothing happens at all if I do that. I have the modules S, P, C, D, X running.

 SMTP-Server settings are:
IP Interface to use: 127.0.0.1

Listen on port: 25 (this is open, not the issue)

TCP timeout: 60 seconds

Connection control allows 127.0.0.1 and my server IP, but doesn't refuse anything. 

What should I be looking for? Thanks

Oh yeah: The problem occures if I try to send mail from hotmail/gmail to my server. Locally it works.

Solved.

I don't know why, but for "IP Interface to use" in the SMTP server settings, I had to use my public IP, not 127.0.0.1.Then 127.0.0.1 for the POP3 server to let me fetch it with Pegasus.

Hope this helps somebody.
