NAME

       imap_ssl_cert - connects to an IMAP server using SSL and saves the server certificate into
       a .pem file

SYNOPSIS

        imap_ssl_cert -H imap.server.com > server_ca_file.pem
        imap_ssl_cert -?
        imap_ssl_cert --help

DEPENDENCIES

       This utility requires the following perl modules to be installed:

       Getopt::Long Mail::IMAPClient IO::Socket::SSL Net::SSLeay

OPTIONS

       --timeout <seconds>
           Abort with critical status if it takes longer than <seconds> to connect to the IMAP
           server. Default is 60 seconds.  The difference between timeout and critical is that,
           with the default settings, if it takes 45 seconds to connect to the server then the
           connection will succeed but the plugin will return CRITICAL because it took longer
           than 30 seconds.  Also known as: -t <seconds>

       --hostname <server>
           Address or name of the IMAP server. Examples: mail.server.com, localhost,
           192.168.1.100 Also known as: -H <server>

       --port <number>
           Service port on the IMAP server. Default is 143. If you use SSL, default is 993.  Also
           known as: -p <number>

       --verbose
           Display additional information. Useful for troubleshooting.

           Also known as: -v

       --version
           Display plugin version and exit.  Also known as: -V

       --help
           Display this documentation and exit.  Also known as: -h
