RFC 821 page 29 (Section 4.1.2 COMMAND SYNTAX)
<mailbox> ::= <local-part> "@" <domain>
<domain> ::= <element> | <element "." <domain>
<element> ::= <name> | "#" <number> | "[" <dotnum> "]"
<dotnum> ::= <snum> "." <snum> "." <snum> "." <snum>
<snum> ::= one, two, or three digits representing a decimal integer value
in the range 0 through 255
The item you missed was the third form of the <element>.
