***RESOLVED***Zentyal 3.3 postfix, unable to receive external emails

[rifaadh]

Hello,

I am presently having an issue to get external emails. I am able to send email to my internal accounts also external accounts. My ISP is blocking the port 25 so i am using there smtp server to replay my email.

My external emails are being replayed via NoIP Reflector service and i am using the port 587, I also tried the port 465.

- The email comes to my server but gets rejected.

- I have already tried Telnet on my server and it works. I was able to connect to the ESTMP. Also i was able to send an email as my Gmail account to my internal account and it worked

Any help will be really appreciated. Here a couple of information. If you need more information please ask.

hey

I AM SOO HAPPY, I FIXED THE ISSUE AND IT WORKS!!!!!!!!!!

- i resolved the matter and i am inputting the resolution so it could help other people if they encounter the same issue


- What i did to resolve the matter:

i recently did an update on zentyal and it screwed up a little my things so i reinstalled everything.

then i did another telnet test but with the port 25 at home and i was able to connect to my server and send the email
but when i did it with the port 587 it failed and gave me the same error message.

- i changed the smtp port to 600 on the /etc/postfix/master.cf and /etc/services and i was able to telnet to the smtp server on my laptop
- also i put my laptop on the 3G and i was able to send an email like from my Gmail to my rifaadh@rifaadh.com
- i inserted in my router to forward the port 600 to my server
- i allowed the port 600 on my server firewall (EX: SMTP: source port= any, destination port = 600)

- i also added the noip mail server in my MX(Mail exchangers) in the DNS section

- i also changed the settings on my Noip account.

To change the smtp port i followed this link:

http://sharadchhetri.com/2013/03/06/how-to-change-smtp-port-number-25-in-postfix/

- Now it works

- it looks like the server does not want to receive email from the port 587.
