Problem receiving emails

Post by agosmart.dz » 2021/05/12 12:27:48

Hello

We have :
centos 7.5
dovecot : 2.2.10
Sendmail : 8.14
Kaspersky Security 8.0 for Linux Mail Server
We have two domains: webcom.dz and algermedina.net



-- When one of our customers tries to send us an email on the first domain: webcom.dz it works fine.

-- But when the same client sends us the same email on the second domain: algermedina.net he receives the following error:

Check the configuration for both domains with a tool like https://mxtoolbox.com/diagnostic.aspx

centos 7.5
And this is not safe to run, it's *years* out of date and needs yum update ruin to get it to 7.9.2009 + latest fixes.
CentOS 6 died in November 2020 - migrate to a new version!

CentOS 5 is dead, do not use it.

In addition to the outdated and easily corrected software that TrevorH mentions -

your webcom.dz both resolves and is accessible from the Internet. Conversely, algermedina.net resolves to an address (that has changed), but no communication gets through to it from the Internet. Check your Kapersky, ISP, firewall.
