I tried to send mails with the command line to multiple recipients in 1 curl command.
I've seen that repeating --mail-rcpt does the work but didn't find any documentation on your web man page
It may be great to add in your documentation that this option could be used multiple times
Good idea. Any suggestion on what to say?
--mail-rcpt (SMTP) Specify a single address, user name or mailing list name.
Repeat this option for multiple recipients
curl.1: --mail-rcpt can be used multiple times
