Default IP Ban settings

abdullah_mudassar

Probably a newbie question, but is there any default IP ban policy for mailcow to automatically ban IP Addresses? Which service is responsible for it?

ETNyx

Yes it’s called Netfilter.

This was very helpful. Thanks. Is there any way I can remove IP Banning for a certain amount of time from my mailcow Instance? I am testing some connections and I believe it is banning my Office IP Address.

ETNyx Also, is there any active discord community or any other platform which is more convenient where I can get faster responses? Although you were very fast in the reply. Thanks for that…

About removing IP for certain time, docs have screen of netfilter settings, there is whitelist textarea, this should work.

About platform, I do not know, but i think not. Using forum as this keep history and one can search what others solved, chats usually don’t.
