250 zardoc.esmtp.org Hi there
This would be an illegal syntax per the ABNF:
address-literal = "[" IPv4-address-literal /
IPv6-address-literal /
General-address-literal "]"
helo = "HELO" SP Domain CRLF
Domain = (sub-domain 1*("." sub-domain)) / address-literal
sub-domain = Let-dig [Ldh-str]
How do you know it's not a domain? Do you perform a DNS lookup?

Hmm, why again are you complaining about my software?
