And partially quoted? I have a bit of problems with ABNF, so
i think
local-part = dot-atom / quoted-string / obs-local-part
means "either dot-atom OR quoted-string", so tests like that from
my IMF parser (which requotes quoted display-names etc so that ie
dictionary lookups on unique keys would match a"b"c "ab"c a"bc"
etc via "abc")
"j ( GoOd ) d\t\"o\" e\t@ t7 . ex ( johnny ) ",
"\0\0\"jdoe\"\0t7.ex\0GoOd johnny\0",
could even be invalid syntax turned to something good (RFC 5322
maximally has
<pete(his account)@silly.test(his host)>
which does not help), but obs-local-part aka
obs-local-part = word *("." word)
word = atom / quoted-string
would at least imply that in between dots partially quoted strings
could occur.
This is nothing postfix worries about, and obs-local-part is
not supported?
