Curious about email alias syntax

Will the following syntax work with all email client tools, SMTP servers, POP3 servers, IMAP servers...

Alias Alias <trueaddress@validdomain.com>

In other words, is this syntax universal, or do different email client tools require different notations. For example:

Alias Alias (trueaddress@validdomain.com)
Alias Alias [trueaddress@validdomain.com]
Alias Alias {trueaddress@validdomain.com}

according to RFC821 and RFC5321, the standard is "<" and ">"


some firewall/anti-spam tools even reject if command if you do not put < bracket.

in the document, you can use rewrite function make it to standard, but again, the standard is < >

sidenote: [ ] have been widely used on Outlook like [fax:+1234567890] to convert it to a fax, but it is not a standard SMTP traffic anymore.
