Error: Failure when receiving data from the peer

[aymenrz]

Hello,

Someone can help me please, I have a problem with zabbix mail notification after upgrading zabbix server from jessie to buster debian version

Error:
Media type test failed.

• Failure when receiving data from the peer

I can sent mail using : curl smtp://smtp.example.com --mail-from [email protected] --mail-rcpt [email protected] --upload-file email.txt

The same for me on centos8+Zabbix5.0.5, can you help us please ??? Maybe it's a bug from Centos8 because it worked fine with Centos7 with the same parameters in zabbix media types

For me it was the old exchange 2010 smtp that not accept the new sercurity protocol for STARTTLS with centos 8 so the solution is to install Zabbix on centos 7 and it works !! So becareful on the smtp server version used.
