### Welcome the check_email_loop plugin repositoryThis script sends a mail with a specific id in the subject via an given SMTPserver to a given email-adress. When the script is run again, it checks for thedelivery of this email based on its unique id in the subject on given POP3/IMAPmail accounts. Using an external mail forward this script enables you to assert basicfunctionality of sending & receiving emails of your email infrastructure.Example``` check_email_loop -poph=host -pa=pw -popu=popts -smtph=host \ -from=root\@me.com -to=remailer\@testxy.com \ -lostc=0 -pendc=2```### NoteThis is a plugin I wrote centuries ago. Meanwhile I do not run any email serversany more, but this plugin still seems to be very useful for a resonable share ofthe nagios users so that many other supplied significant improvements andextensions to this plugin. I'm very happy that my little script has become partof this lively open source community.Though I wont' be able to further maintain this plugin on my own, I'm stilltrying my best to integrate code contributions I receive via email and sharethem at this place. So if you have a litte code change correction you feel itshould find it's way into the public: just fork the GitHub repository and giveme a short note.Please also check the user comments on this plugin as they might contain morecurrent information.
