[MAILER-DAEMON@mira.linknet.com.au: Undeliverable Mail]
I've been getting these periodically from one of my list members' servers and I'm curious... is To: user@domain.com <user@domain.com> really an invalid address? MailMAX is the only server I've ever seen thrown an error on this.
I keep meaning to email them and ask what's up, since it seems like a bug to me, but before I do, does anyone know if this is actually an invalid address and other servers just deal with it?

According to my reading of RFC 2822 3.4, no, it's fine: if a mailbox can be a name-addr, and a name-addr is a display-name followed by an angle-addr, then the display-name should be treated as a comment by any mailre, provided that the angle-addr is syntactically correctly constructed.
But this is more properly a topic for comp.mail.headers. (Does that NG still exist? ;-)

I thought it was legal, but on reviewing RFC 822, I find that it is, in fact, invalid: if the phrase outside <>'s contains any of spaces, ctrls or:
specials = "(" / ")" / "<" / ">" / "@" ; Must be in quoted- / "," / ";" / ":" / "\" / <"> ; string, to use / "." / "[" / "]" ; within a word.
...it must be quoted: To: "user@domain.com" <user@domain.com>

As others have said, no.

Try it against my exim server. I've enabled its syntax checking which causes it to reject messages like that. (it also rejects a good number of spam messages with bogus headers)
