# Program name imapCapability.pl #
# Written by Rick Sanders #
# Date 23 December 2007 #
# #
# Description #
# #
# imapCapability.pl is a simple program for querying an IMAP #
# server for a list of the IMAP features it supports. #
# #
# Description #
# #
# imapCapability is used to discover what services an IMAP #
# server supports. #
# #
# Usage: imapCapability.pl -h <host> -u <user> -p <password> #
# Optional arguments: -d (debug) -m (list folders) #
# #
# Sample output: #
# The server supports the following IMAP capabilities: #
# #
# IMAP4 IMAP4REV1 ACL NAMESPACE UIDPLUS IDLE LITERAL+ QUOTA #
# ID MULTIAPPEND LISTEXT CHILDREN BINARY LOGIN-REFERRALS #
# UNSELECT STARTTLS AUTH=LOGIN AUTH=PLAIN AUTH=CRAM-MD5 #
# AUTH=DIGEST-MD5 AUTH=GSSAPI AUTH=MSN AUTH=NTLM #
