When I check with the FETCH command, I get like this:
2148 FETCH (UID 2159 INTERNALDATE "06-Nov-2013 06:36:15 +0000" RFC822.SIZE 3702 ENVELOPE ("Wed, 6 Nov 2013 12:06:39 +0530" {19} Reg: "test subject" (("karthick kumar" NIL "ngkarthick" "aroxo.com")) (("karthick kumar" NIL "ngkarthick" "aroxo.com")) (("karthick kumar" NIL "ngkarthick" "aroxo.com")) ((NIL NIL "phpkarthick" "gmail.com")) NIL NIL NIL ""))
There is some thing unwanted {19} in fetch command
