Anybody can recommend a certificate expiration checker that can check certificates for HTTP, SMTP, IMAP, POP3 ?

Need to track a few certificates and get a notification when they are about to expire. Just can't seem to find any decent free software.

  • I don't know of any existing software that does exactly this, but in theory it shouldn't be too hard to write up a script that does this using the OpenSSL command. – Austin Hemmelgarn Dec 17 '18 at 19:25
