DEPENDENCIES

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

--usage
