I found http://www.jfranken.de/homepages/johannes/vortraege/ssh2.en.html. The solution is to make exim talk smtp to a pipe. ssh takes this smtp dialog on stdin and netcat on the remote machine feeds that to the mail server.
In the transports section I put: # Transport, which tunnels mails over ssh to my smarthost ssh: driver = pipe # talk regular smtp to the pipe (qmail approved :-) ) bsmtp = all bsmtp_helo = true use_crlf = true prefix = "" suffix = "" # connect to my mail server's smtp port. # must authenticate without password command = ssh -l <user> <host> 'nc -w 1 <smtp server> smtp' user = <local user> # ssh failure handling: kill hanging sessions, # retry and tell me on failures timeout = 300s temp_errors = 1 return_fail_output = true And in the routers section there is sshpipe: driver = domainlist transport = ssh route_list = "*" Important to note is that you need to enable ssh's public key authentication to not have it ask for a password. Key authentication has to work for user = <local user> in the line after the ssh command. BTW, I use exin 3.36, I believe this has to work with other versions, too.
