Summary: Cannot sub address using dotted quad

Initial Comment:
There is no way to subscribe someone at a dotted quad 
IP address.  The argument of

     userx@[1.2.3.4] 

is rejected as an "illegal" address (although this is in fact 
the RFC correct way to do it).  Interestingly, I can use

     userx at 1.2.3.4   (note lack of brackets)

successfully, but since this is technically not RFC 
compliant,  many MTAs will refuse to accept it (e.g., 
postfix, and probably others).  For example:

220 mx1.mfn.org ESMTP Postfix
ehlo mfn.org
250-mx1.mfn.org
250-PIPELINING
250-SIZE 10240000
250-VRFY
250-ETRN
250 8BITMIME
mail from: userx at mfn.org
250 Ok
rcpt to: antisocial at 192.168.155.108
501 Bad address syntax
rcpt to: antisocial@[192.168.155.108]
250 Ok
quit
221 Bye
