DATA terminates the envelope. AFTER_HEADER should be fired after the blank line, which terminates the header:
MAIL FROM: ... --> AFTER_MAIL_FROM RCPT TO: ... --> AFTER_RCPT_TO DATA From: ... To: ... Subject: ... --> AFTER_HEADER [blank line] Mail body .. [dot] Each event hook should submit its preceeding data to the script: AFTER_MAIL_FROM submits the MAIL FROM line AFTER_RCPT_TO submits the RCPT TO line. AFTER_HEADER submits all lines between DATA and [blank line] There is one special thing:=20 Since there can be multiple RCPT TO lines, the event should fire with the last RCPT TO, submitting all lines before. --Harald > -----Urspr=FCngliche Nachricht----- > Von: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] Im Auftrag von Rob Arends > Gesendet: Dienstag, 3.
