Feb 03, 2005regexp looking for email addresses in iRule
Toying with some stuff and thought I'd like to scan TCP payload for email addresses, preferably in the "MAIL FROM", but I'm starting much bigger for sake of easing into this. Anyhoo, not having much ...

Hi,
I believe you're posting in the wrong forum. You probably want the v9 iRules forum, not iControl, which is our API to configure the system.
I'm a bit swamped right now, but to give you a quick, short answer, the problem is that SMTP is an interactive protocol. As in, you connect and get a banner, then you send the next command, get a response, etc. etc.
We can inject data/respond to a TCP stream. Take a look at the TCP::respond command. I'll try to write in more detail later, but perhaps someone else on the forum can assist for now. (And as I mentioned, you might want to move the thread so others get to see it.)
