💖 IMAP_SSL_CERT 💖

okay so bestie, this is the manual for imap_ssl_cert, from the User Contributed Perl Documentation corner of the universe. It's a whole little utility that slays in the most specific way possible. Let's get into it 🫶

✨ NAME ✨

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

like... it just goes and gets the cert for you. no cap.

🌸 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, fr fr, no skipping:

  • 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 — Display a short usage instruction and exit.
