Cant receive emails
« on: June 07, 2019, 10:55:24 PM »
Hi Guys! how are you? My first post Here :)

I am surprised of how easy was to setup everything on CentOS web panel. I deployed a VM and in 5 minutes I got almost everything Up and running.. Still amazed with that.

The only issue that I encountered so far is that I cant RECEIVE emails. I created an email account, mails are perfectly going out, but if I reply or send an email to that same account I never receive it..

DNS are pointing to the server
MX are correctly setup
AntiSpam is disabled
mailqueue is empty
Tried rebuilding mailserver configuration
I have SPF enabled
I have DKIM Enabled.
Emails are perfectly going out with roundcube...

domain: simplecredito.com.ar  (Issue is with incomming emails..)


Any idea on that will be helpfull..

Thanks!

Is firewall blocking access inbound?

Can you telnet on your IP for port 25,143 or 110?

for example telnet x.x.x.x 25

No, I cant telnet... I get timeout... so almost sure there is the problem..

My question now is.. how can it be blocked? I only enabled CSF in the default configuration. can that be causing the issue? Should I enable port 25 in the CentOS web panel configuration?

PS: I tried disabling CSF and I still get "timeout" when trying to "telnet IP 25"


Thanks!

Solved, it was a firewall rule that was droping connections to port 25. (by default they block port 25). I raised a ticket with them and they enabled port 25.


now mails work like a charm.

Thanks :)
