Any pointer on how to set “a whole test email server” ?
For instance, I’m using Postfix (on Debian host) to send email though my ISP SMTP relay.
Having a “dry run” mode in Postfix with which outbound emails would be logged but not sent, would be perfect.
Using “sendvoicemail=no” in the [general] section of /etc/asterisk/voicemail.conf is not as convenient as think I can’t read in log files that Asterisk would have sent an email if this option had been set to yes.
In web app development, you can read references to Mailhog or equivalent as what to test without spamming anyone.
As I’ve never used Mailhog, I don’t know if it fits my requirements.
