Not Receiving Mail

[TGates]

The '454 4.7.1 <test@example.com>: Relay access denied [641 ms]' is GOOD. It is the check for open relay and yours is closed. Therefore 'Relay access denied'.

Your warnings are:
SMTP Banner Check - Reverse DNS does not match SMTP Banner
SMTP TLS - Warning - Does not support TLS.

Servers by default are denied relays.

Only authentificated clients will be authorised relay or otherwise accept emails that you host. This is how the setup works.

So I need to disable TLS? And how do i check the Banner?

[Me.B]

Yep TLS setup don't look good.

Hello im still having problems sending and receiving emails. In both Roundcube and in external clients like Outlook and Android Mail. Where can i look to see if there are errors when trying to connect or send mail?

Thanks in advance.

[TGates]

In your rmail log, mail error log, dovecot log, /var/log/ and/or /var/sentora/logs/

Im sorry i havent replied. Ive been busy with work all week trying to find time to sit down and look at the logs.

If i can get sometime to night ill take a look. Sucks because all emails are broke. Cant send or recieve. But i can send emails to other emails on the same host.

Ill post back with more info when im by a computer.

I can send and recieve within my host's network. So im getting email notifications of wordpress installation updates.
I can NOT send or recieve OUTSIDE of my host's network. So no sending to Yahoo, Gmail, AOL etc.

Cant not use either Roundcube or an external mail client they both have a sending message progress loop.

When i do send mail to my gmail account i get...

Code:

About the sending, are you using a smtp relayer? I use my ISP's or you can use gmail. If you are trying to send mail straight out of your server to gmail, etc. it will get denied 99% of the time especially if your ip/mail server is blacklisted.

[Surf3rDud3]

I am not using a relay... i shouldn't have too when nothing is being blocked or blacklisted. Ive checked all my ports are open, and checked the blacklist all clear and it was working a few days ago. Plus its not only sending emails its also receiving i have gotten an external email since the 10th.
