Hello
It appears that Postfix considers addresses beginning with a dash as
invalid:
----8<----
cob...@iridium:~ $ telnet localhost 25
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
220 iridium.planetcobalt.net ESMTP
helo planetcobalt.net
250 iridium.planetcobalt.net
mail from:<-...@planetcobalt.net>
501 5.1.7 Bad sender address syntax
mail from:<a...@planetcobalt.net>
250 2.1.0 Ok
quit
221 2.0.0 Bye
Connection closed by foreign host.
---->8----
However, if I understand RFC 2822 correctly, '-' is a valid character
even at the beginning of an address:
local-part = dot-atom / quoted-string / obs-local-part
dot-atom = [CFWS] dot-atom-text [CFWS]
dot-atom-text = 1*atext *("." 1*atext)
atext = ALPHA / DIGIT / "!" / "#" / "$" / "%" / "&" / "'" /
"*" / "+" / "-" / "/" / "=" / "?" / "^" / "_" / "`" /
"{" / "|" / "}" / "~"
Is this a bug, or did I miss something?
My config is:
----8<----
