Is this a valid address?

08:04:33.934 C: MAIL 
FROM:<github.agent:.github-hookshot/7431eee@winserver.com>
08:04:34.712 S: 250 2.1.0 Ok

with the ':' and also '/' ??

It appears to be accepted by various servers, including my own.

This is related to a new project of handling a GitHub Webhook HTTP 
notifications sent to my web server.  The handler will the payload as 
a local message using the address:

From: github agent: github-hookshot/7431eee

That comes from an operator defined macro:

From: github agent: {GITHUB-AGENT}

Which is read from the JSON payload.

If the setup happens to send the notification to an email address, 
then the mail is exported for SMTP to sent out.

So I need to know if the address is valid. Its hard to decipher 
whether it is or not from the RFC5322/RFC5321 BNF. It seems to read 
the ':' and '/' characters are valid.

Thanks
