Yeah I know but when you look at https://testconnectivity.microsoft.com/ there are no problems. Also allot of other people are experiencing this starting from saturday.
At this time it works for me, but there are still people complaining.

Yes I have seen those to.
It seems that it is a certificate issue with microsoft. Also more people are experiencing the same.
My little brother even suggested a man in the middle attack.

E-Mail / Re: Not able to mail when ClamAV, Amavis & Spamassassin are activated
« on: November 20, 2016, 01:40:51 PM »
To add..
I always have problems with rebuilding postfix and amavis. Everytime I have permissions errors with logs.
Have to manually chmod and create the log path/directory for clamav.
After that most of the time it works good.
Occuring on hyper-v and openvz VMs with Centos panel

Another strange issue with sending to 365 mail servers from a centospanel server.
In the log it shows it is delivered but it never reaches the inbox of the 365 recipient,

I did multiple times.
I had to manually uncomment things in the main.cf to make it work again.

Postfix / 365 servers cannot be reached. (mail.protection.outlook.com) (no ban)
« on: November 20, 2016, 12:09:36 PM »
Hello everyone.
I found problems reaching Microsoft 365 mail servers.
The following error occures:
I can send mail to Gmail/Hotmail/Outlook.com/Live and receive it.
Also the problem occures on other Centospanel servers.
Could it be that I need a real SSL certificate and not self signed?
When I test it on testconnectivity.microsoft.com there are no problems. Everything is in the green! (No ban)
All rbl's in the green.
Maybe the *.mail.protection.outlook.com having problems with selfsigned certificates?

Does your master.cf in /etc/postfix looks like this?
Code: [Select]
smtp inet n - n - - smtpd
-o content_filter=smtp-amavis:127.0.0.1:10024
-o receive_override_options=no_address_mappings
#
## Enable SMTP on port 587 only for authenticated/TLS clients
submission inet n - n - - smtpd
-o smtpd_enforce_tls=yes
-o smtpd_sasl_auth_enable=yes
-o smtpd_client_restrictions=permit_sasl_authenticated,reject
## Enable SMTP on port 465 only for authenticated/SSL clients
smtps inet n - n - - smtpd
-o smtpd_tls_wrappermode=yes
-o smtpd_sasl_auth_enable=yes
