Bad karma problem

[André Abreu]

Hi,

First off all let me thank you for this awesome project.

After updating from poste v1 to poste v2 some emails were not sent. After some debug I realize that the issue was from karma records.

554 very bad karma score: -10

For some reasons (I think) karma gets a negative value because the client send some unknown commands. The client in this case is Microsoft Outlook.

I thinking to change haraka-plugin-limit configs or even disabling it in config/plugins. I want to know what is your opinion about this?

Thanks, André Abreu

I found a similar issue to this but I discover if you set "Invalid connections count threshold" to 100 (System settings / Advanced tab), this mostly disappears

Please setup all your clients to port 587 or 465 with SSL/TLS and authentication!

• these ports has no delay, no karma and are supposed to accept emails from regular people
• port 25 is determined to accept emails from other mailservers
