The ``:'' should be encoded as ``=3a''. Please file a bug with the
Thunderbird maintainers. They violate RFC 5322 syntax rules, and
their bug cannot be fixed by changing Postfix.
In RFC 5322 the ``:'' is a special character, and RFC 5322 allows
only atom or quoted-string as the "phrase" portion of an address.
Relevant rules from RFC 5322:
name-addr = [display-name] angle-addr
angle-addr = [CFWS] "<" addr-spec ">" [CFWS] /
obs-angle-addr
display-name = phrase
phrase = 1*word / obs-phrase
word = atom / quoted-string
atom = [CFWS] 1*atext [CFWS]
atext = ALPHA / DIGIT / ; Printable US-ASCII
"!" / "#" / ; characters not including
"$" / "%" / ; specials. Used for atoms.
"&" / "'" /
"*" / "+" /
"-" / "/" /
"=" / "?" /
"^" / "_" /
"`" / "{" /
"|" / "}" /
"~"
specials = "(" / ")" / ; Special characters that do
"<" / ">" / ; not appear in atext
"[" / "]" /
":" / ";" /
"@" / "\" /
"," / "." /
DQUOTE
See especially the last rule which says that ":" cannot appear
in atext.
