Filter mail based on content using regex/strcmp?
-
Dear Takayuki,
こんにちは
Can I use before_send_mail() to deny form submission/sending of mail based on some custom checks ?
How/where can I check against the sender email or the title or the content for a string comparison, or regex against the text. for example, if the content of the message contains a bad word or the email address is a specific domain.
I know there is a spam plugin, but I want to do something more custom.
