Hello,

I have a mail server running Amavis and Postfix, which were configured from a web-based tutorial.

I really have no idea about the inner workings of these email protection solutions, and I really hope I've configured them correctly.

However, in my Logwatch, I see lines like this:

What does "RelayedOpenRelay" mean ?
It means that my Postfix is open ? I really hope not!

I've done some testing at mxtoolbox.com and it doesn't seem to be open.
However, I think mxtoolbox.com tests on Port 25.
What about other open ports used by Amavis ?

I really don't know the flow of events of how these solutions work.

I googled for a few hours before I found that something must be done in @mynetworks and local_maps, I don't know... However, I don't have amavis.conf file in my system...

Anyone has any experience with Amavis ? Can anyone help me set up amavis accordingly ? And what does "RelayedOpenRelay" mean ?

Thank you !!

Putting your exact message into Google pulls up, on the first page of hits:

...an explanation of what that is, and how to turn it off. Since you don't say what tutorial you used, what environment you're in, or what you need these things to actually do, there isn't a lot we can tell you. We can't guess. However, since you've been asking about mail for a while now (and 'bumping' your own threads, making them less visible):
https://www.linuxquestions.org/quest...in-4175694736/
https://www.linuxquestions.org/quest...rs-4175712786/
https://www.linuxquestions.org/quest...ms-4175705655/

..you should have a decent understanding of things. What is the actual PROBLEM you're having?? And yes, there are people who can help you set things up, but you first have to clearly define what it is you're trying to do, then explain to us where you're stuck and what you've tried; same for any problem you're having. Otherwise, you can hire a consultant to come do this all for you.

Also, putting "amavis open ports" into Google pulls up: https://rtcamp.com/tutorials/mail/server/port-numbers/
...which tells you what ports are used. Hard to believe that you spent hours looking for these things, when they were found in seconds.

Sorry for the late response, I was away a few days.
I will post the entire problem, soon.
Thank you !
