Hello.

I'm running a small mail server with postfix and I'm seeing a lot of weird stuff in the syslog. I'm not receiving any emails as of yesterday.

This is what's in syslog:

I don't know if someone is trying to hack my server or what.
Please guide me to where I can find information and how can I fix this...

Thanks in advanced for your help.

I tried running a test in mxtoolbox and now I get this:


smtp:190.80.159.7
