It should be already included in most Linux distributions. Otherwise you can find it here: https://github.com/jetmore/swaks You can check the whole SMTP-Protocol chain, or you can tell swaks after which step to abort. Your use case would be stopping after RCPT, so you would start it using the extra flag "-q RCPT" Julian -- --------------------------------------------------------- | | Julian Kippels | | M.Sc.
