[9fans] smtpd using 9front

[g_patrickb@yahoo.com (G B)]

Previously I was using OpenSMTPD on OpenBSD for my smtpd server, but I thought I'd try the 9front smtpd server, but I have some questions if anyone would care to indulge me in getting it setup for multiple domains to accept and send mail.


Under
7.7 - Mail server configuration and maintenance

7.7.1
For the smtpd.conf file the line would read:
ourdomains domain1.org, domain2.net, domain3.com

7.7.2
For the rewrie, the line would read:
(ttr|domain1.org|domain2.net|domain3.com)!(.*)??? alias \2

7.7.4 
remotemail is where I am a little lost in what to use for multiple domains:

7.7.5 SMTP over TLS
Do I create a certificate for each domain?

Lastly, what do I enter in /cfg/$sysname/cpustart to start smtpd each time the server boots?

Thanks for any help and I apologize for my ignorance.
