that is not my IP Address
EnglishWhitelist forwarding host
maybl8 Where do I find this and if it is in a whitelist why is it listed in the spam places?
Please rephrase your question, I don’t get what you want to know
maybl8 Where do I find this and if it is in a whitelist why is it listed in the spam places?
Why do you think it is whitelisted? “DUNNO” means “Don’t know”, so the whitelist does not know this IP.
OK so I guess what I am asking is. This statement in postfix log:
“whitelist_forwardinghosts: Look up 58.27.204.130 on whitelist,”
What is this saying? Other ip’s listed in the log don’t say this
Why is it trying to look this ip up on a whitelist and where is this whitelist?
I’ve looked and I don’t have it in any whitelist. I only have email adresses in a whitelist.
maybl8 What is this saying? Other ip’s listed in the log don’t say this
It’s checking the remote IP against your whitelist. I get this message for every remote IP which is trying to send an email
Sorry to be ignorant here.
I don’t look at logs too often so after looking at the logs some more I see some other messages similar to this one.
One more question where is this whitelist that it is looking at? Is it creating one dynamically? Like I said I only have whitelisted email addresses.
Whitelist
Whitelisted email addresses are programmed to never classify as spam. Wildcards may be used. A filter is only applied to direct aliases (aliases with a single target mailbox) excluding catch-all aliases and a mailbox itself.

It’s in the Mailcow UI
System -> Configuration -> Options -> Forwarding Hosts
There is nothing there:
Forwarding Hosts
Incoming messages are unconditionally accepted from any hosts listed here. These hosts are then not checked against DNSBLs or subjected to greylisting. Spam received from them is never rejected, but optionally it can be filed into the Junk folder. The most common use for this is to specify mail servers on which you have set up a rule that forwards incoming emails to your mailcow server.

You can either specify IPv4/IPv6 addresses, networks in CIDR notation, host names (which will be resolved to IP addresses), or domain names (which will be resolved to IP addresses by querying SPF records or, in their absence, MX records).

Yes, that’s the reason for
Look up 58.27.204.130 on whitelist, result 200 DUNNO
DUNNO because the IP isn’t found in the whitelist

OK in studying this more. It appears that if postfix can’t relate the ip address to a domain it looks in the forwarding hosts whitelist for the ip. If it doesn’t find it that is when it displays that message DUNNO..
Sorry this is something I didn’t understand on postfix operation. There is always something new to learn.
