Failure when receiving data from the peer After upgrading to DB10

[aymenrz]

Hello,

I upgraded zabbix from jessie to buster debian version, and now I have a problem with zabbix email, when I test mail notification from zabbix I have this 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


Someone can help me please ?
