Postfix Can Send But No Incoming Email Arrive
 
Hello all -

I've been able to modify my postfix configuration so I can send email out on port 587, but when I tried to send an email to myself from Gmail or from work, I don't receive any emails.

Does someone have any idea why this is happening and perhaps a way to see why incoming emails are being blocked ?

Thanks !

Mike

Does the MX record of your domain point to the correct server?

The MX and A records still point to my mail server, as they have for the past 10 years. If I'm relaying through Gmail, I don't need to them, do I ?

I also called my ISP and they said:
- they are blocking port 25 both inbound and outbound
- If I set up SSL, inbound is port 995 and outbound is 465
- If no SSL, inbound is port 110 and outbound is 587

I'm guessing by "SSL" he meant "TLS".

Here is a snippet of my master.cf:
# Postfix master process configuration file. For details on the format
# of the file, see the master(5) manual page (command: "man 5 master").
#
# Do not forget to execute "postfix reload" after editing this file.

that is your problem , outside mail servers will always try to comunicate with your MX on port 25 , if you ISP is blocking it then you wont get any mail
ask them if they provide a smart host that you can use for relaying mail
