Hello!Could you help me where is the syntax error in this address? Jun 6 21:39:09 szerver4 courieresmtpd:error,relay=::ffff:195.228.245.161,from=<optimail-%9566%- %22342...@optimail.hu>: 517 Syntaxerror. AFAIK this is a very high volume newsletter.
Unfortunately, this "high volume newsletter" violates RFC 2822 with its email address.
From section 3.4.1 of RFC 2822:
addr-spec = local-part "@" domain
local-part = dot-atom / quoted-string / obs-local-part
In this case, the "dot-atom" form of local-part applies.
Section 3.2.4 spcifies dot-atom as follows:
atext = ALPHA / DIGIT / ; Any character except controls,
"!" / "#" / ; SP, and specials.
"$" / "%" / ; Used for atoms
"&" / "'" /
"*" / "+" /
"-" / "/" /
"=" / "?" /
"^" / "_" /
"`" / "{" /
"|" / "}" /
"~"
atom = [CFWS] 1*atext [CFWS]
dot-atom = [CFWS] dot-atom-text [CFWS]
dot-atom-text = 1*atext *("." 1*atext)
In other words, the "%" character is a prohibited character in email
addresses.
