I would like to warn others users about spamrbl.imp.ch which is included in PMG default installation:
All my users where prevented to receive incoming mails from hotmail.com and outlook.com in the last days.
I know that freemails are terrible but my users include real-estate, medecine doctors and they have to deal with their customers who are individuals, not companies.
Even if recently a lot of junk is coming from Microsoft and Gmail, you cannot block the ip's and domains of these major providers
unless you deal ONLY with Fortune100 companies !
It tooks me a while to figure where this blacklist was located, after looking into SpamAssassin rules, I found it more easily in the GUI in mail proxy options.
