[置顶]Email验证的正则表达式

      这个Email验证的正则表达式基本符合RFC3521规范,缺少ipv6部分的验证。

        Mail=("([\\x20-\\x21\\x23-\\x5B\\x5D-\\x7E]|(\\\\[\\x20-\\x7E]))*"|^[-!#$%&\'*+/0-9=?A-Z\\^_`a-z{|}~]+(.[-!#$%&\'*+/0-9=?A-Z\\^_`a-z{|}~]+)*)@([a-zA-Z0-9]+([\\-\\da-zA-Z]*[a-zA-Z0-9]+)*(\\.[a-zA-Z\\d]+([\\-\\da-zA-Z]*[a-zA-Z0-9]+)*)*|[\\[]((1[0-9][0-9]|25[0-5]|2[0-4][0-9]|0[0-9][0-9]|00[0-9]|[0-9][0-9]|[0-9])\\.(1[0-9][0-9]|25[0-5]|2[0-4][0-9]|0[0-9][0-9]|00[0-9]|[0-9][0-9]|[0-9])\\.(1[0-9][0-9]|25[0-5]|2[0-4][0-9]|0[0-9][0-9]|00[0-9]|[0-9][0-9]|[0-9])\\.(1[0-9][0-9]|25[0-5]|2[0-4][0-9]|0[0-9][0-9]|00[0-9]|[0-9][0-9]|[0-9]))[\\]]|((1[0-9][0-9]|25[0-5]|2[0-4][0-9]|0[0-9][0-9]|00[0-9]|[0-9][0-9]|[0-9])\\.(1[0-9][0-9]|25[0-5]|2[0-4][0-9]|0[0-9][0-9]|00[0-9]|[0-9][0-9]|[0-9])\\.(1[0-9][0-9]|25[0-5]|2[0-4][0-9]|0[0-9][0-9]|00[0-9]|[0-9][0-9]|[0-9])\\.(1[0-9][0-9]|25[0-5]|2[0-4][0-9]|0[0-9][0-9]|00[0-9]|[0-9][0-9]|[0-9])))
      RFC3521中的相关定义:
              Domain         = sub-domain *("." sub-domain)
              sub-domain     = Let-dig [Ldh-str]

   Let-dig        = ALPHA / DIGIT

   Ldh-str        = *( ALPHA / DIGIT / "-" ) Let-dig

   address-literal  = "[" ( IPv4-address-literal /
                    IPv6-address-literal /
                    General-address-literal ) "]"
                    ; See Section 4.1.3

   Mailbox        = Local-part "@" ( Domain / address-literal )

   Local-part     = Dot-string / Quoted-string
                  ; MAY be case-sensitive


   Dot-string     = Atom *("."  Atom)

   Atom           = 1*atext

   Quoted-string  = DQUOTE *QcontentSMTP DQUOTE

   QcontentSMTP   = qtextSMTP / quoted-pairSMTP

   quoted-pairSMTP  = %d92 %d32-126
                    ; i.e., backslash followed by any ASCII
                    ; graphic (including itself) or SPace

   qtextSMTP      = %d32-33 / %d35-91 / %d93-126
                  ; i.e., within a quoted string, any
                  ; ASCII graphic or space is permitted
                  ; without blackslash-quoting except
                  ; double-quote and the backslash itself.
