External SMTP not working

ThisWebDesignUK · Post by **ThisWebDesignUK** » Tue May 16, 2017 7:13 pm

Hello,

I'm just trying to setup VESTACP as a little control panel for a small VPS that I am running on the side. Currently, everything is working perfectly, the only issue I'm having is that when I go to add my email accounts to places such as Outlook 2010, or Apple Mail on iPhone the SMTP does not work.

A few things to note:

Vultr Hosting VPS running Ubuntu 16.04 x64
Exim showing as Exim4
Running mutliple domains
SMTP working when sending from the domain.tld/webmail (roundcube)

I hope this is a small problem that can be fixed easily.

Things I have looked into:
Reverse DNS - Not sure whether this is set correctly
In exim4.conf.template - # infront of hostlist (whitelist / spammers)

Hopefully someone can help me?

EDIT - I have not got any form of SSL certificate, only that with the default VestaCP installation

You can try to check the connection to your smtp server manualy. Run the following command from your client:

Code: Select all

telnet yourserver 25

I believe the problem is also that I'm sending all the DNS traffic to two different servers. This means that I believe It's not setting it correctly. Will be running on a different domain from now but would still greatly appreciate any suggestions.. Does this happen to anyone else running Vesta with Vultr Hosting?

Vultr block port 25 for outgoing traffic by default.
Using other ports
