I've made one post on this site, which was dismissed, and put on hold as a home/hobby/end user problem, and asked me to have it moved to the Raspberry Pi sibling site.
Frankly, not wanting to dismiss the Pi subsite, I don't think that most located there, have relevance to a business to business IPSEC wan scenario for mailbox replication. It's not a home project.
The Pi devices have many places of use in small to medium businesses keeping costs low as standby DNS and MX servers.
The problem I described was not even with the Pi, but the Xeon x64 server, in the data centre 850 miles away.
Why do some moderators have a problem with this?
It seems that "Raspbian" is a tag for an instant downvote.
This is making me feel unwelcome. I've put good input in, and I get treated like trash by a snob.
