Question
What does rejected after DATA: malformed address: xx@yy may not follow <xx@yy> : failing address in "from" header mean?
Answer
Your DATA ACL contains
verify = header_syntax
and an incoming message contained the line
From: xx@yy <xx@yy>
This is syntactically invalid. The contents of an address in a header line are either just the address, or a “phrase” followed by an address in angle brackets. In the latter case, the “phrase” must be quoted if it contains special characters such as @. The following are valid versions of the bad header:
From: xx@yy From: "xx@yy" <xx@yy>
though why on earth anything generates this kind of redundant nonsense I can't think.
