NimbostratusLooking for an example i-rule that can modify SMTP packet and add an x-header. We have products that scan mail and do actions based on x-header. I want the F5 to add text to a new x-header so that a specific action can be done to that email. The pool members of the VIP are the products that do the action on the email. Hope this is clear.

There are no native SMTP commands in iRules, which would allow you to insert an SMTP header in requests. You would need to collect the SMTP TCP data, insert the new X- header into the payload and then replace the original payload with the new one. There is an SMTP proxy iRule in the Codeshare which may be a helpful reference Click Here.
TCP::payload wiki page Click Here also has some good examples there.
I hope this helps
