But all of them are fragile for authentication purposes.

Firewalls can only filter on contents in network packets, typically IP addresses, ports and in some cases MAC addresses. I have no financial interest in it, other than being a satisfied customer. Actually, using SSH port forwarding is safer than PNAT, because there you have an authenticated connection to your bridge VM.

Useful for those times when I need to provide an address but don't want it to be useful beyond the one time I need to get some activation set up. Then Mail sorts them for me by the 'To' address. I use, which has a terrific spam filter and allows three aliases. If that fails, there are third party mail systems that allow multiple aliases. the challenge would be that the three would all have the same sending server, and Mail may (I really don't know) decide to dump those addresses into one account because of the SEND server, despite different account names. When you click on he From address, a window will open with all of the options that you have set up.ĮDIT: Just to be clear, you would set up an email address, say, or whatever it is, for one purpose, then create a second address, say for the second account, and for a third purpose, etc. The only complexity in this is that when you SEND an email, you will need to remember to choose the correct 'FROM' address in the composition window.

In the sidebar, they will each show up individually, with their own Inbox, Drafts, Sent, Junk, Trash, etc., folders. To pick up on Sly's excellent suggestion, create multiple mail accounts, one for each purpose.
