':' is not valid in a local part (unless quoted).
It appears to be accepted by various servers, including my own.
Well, most mail servers accept all kind of garbage ("be liberal ... ").
Mine doesn't:
Mail from:<github.agent:.github-hookshot/7431eee(_at_)winserver(_dot_)com>
501 5.1.7 Bad sender's mailbox address syntax.
Just quote it and you're ok:
<"github.agent:.github-hookshot/7431eee"@winserver.com>
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.
Where do you see an unquoted ':' as valid in "Local-part"? ':' is
used to separate "At-Domain" parts.
