Re: Sending Unencrypted E-mails

Hello.

Incoming SMTP (receiving emails) is intrinsequely different from sending
emails.

Sending emails is govern by RemoteDelivery mailet within
mailetcontainer.xml. To get RemoteDelivery trusted by third parties you can:

 - Enable optimistic STARTTLS upgrades - email relaying happens on port
25 wich is not encrypted by default.
 - Specify valid certificates for the javax SMTP lib:
-D/javax/.net.ssl./trustStore=...
 - /Have a reasonnable reverse DNS being resolved for the IP of your
outgoing mail server.../
 - /Configure SPF [1] and DKIM [2] for your domain

Good luck, sending emails is a challenging topic!

Best regards,

Benoit
