mailremind is a web-based service that sends you mails with a delay-
I often send myself an email to remind me of something. If the event I want to be remindered of is in the not-so-close future this method does not work so well, since the mail is then not new any more. Also mailremind allows you to send mails repetetive based on a schedule, so it can be used for reoccurring events, like birthdays.
Get the sources and build mailremind with go build.
Or simply run go get github.com/silvasur/mailremind. This will place the compiled binary in your $GOPATH/bin directory.
All config stuff is in the mailremind.ini file.
Simply run ./mailremind -config mailremind.ini and mailremind will listen on the configured address (net.laddr) and handle http requests.
