| # POP3 - Post Office Protocol version 3 (popular e-mail protocol) - RFC 1939
 | |
| # Pattern attributes: great veryfast fast
 | |
| # Protocol groups: mail ietf_internet_standard
 | |
| # Wiki: http://www.protocolinfo.org/wiki/POP
 | |
| #
 | |
| # This pattern has been tested somewhat.
 | |
| 
 | |
| # this is a difficult protocol to match because of the relative lack of 
 | |
| # distinguishing information.  Read on.
 | |
| pop3
 | |
| 
 | |
| # this the most conservative pattern.  It should definitely work.
 | |
| #^(\+ok|-err)
 | |
| 
 | |
| # this pattern assumes that the server says _something_ after +ok or -err
 | |
| # I think this is probably the way to go.
 | |
| ^(\+ok |-err )
 | |
| 
 | |
| # more that 90% of servers seem to say "pop" after "+ok", but not all.
 | |
| #^(\+ok .*pop)
 | |
| 
 | |
| # Here's another tack. I think this is my second favorite.
 | |
| #^(\+ok [\x09-\x0d -~]*(ready|hello|pop|starting)|-err [\x09-\x0d -~]*(invalid|unknown|unimplemented|unrecognized|command))
 | |
| 
 | |
| # this matches the server saying "you have N messages that are M bytes",
 | |
| # which the client probably asks for early in the session (not tested)
 | |
| #\+ok [0-9]+ [0-9]+
