(OPTIONAL) For extended tests during 'make test', create a file
'test.txt' in the top level directory of this distribution (the same
directory as the Makefile.PL, etc.).  This file must contain an IMAP
server name or IP (server=...), a user account (user=...), and a
password (passed=...).  A port (port=....) and an authentication
mechanism to be used (authmechanism=...) can also be specified.

Example:

--- BEGIN: test.txt ---
server=localhost
user=mytestuser
passed=mypassword
port=143
--- END: test.txt ---

NOTE: When testing is completed, be sure to remove test.txt (either by
hand or by 'make clean').
