NimbostratusSMTP support with X-Forwarded-For in One-Armed Deployment
referencing to one of the KBs i read in DevCentral, there it was mentioned that X-Forwarded-for does support SMTP Traffic as well, in addition to HTTP. I just need to be sure on this. Can anyone please clear my doubts or give some more elaborations on this.

Not at all true. XFF is an HTTP header.
SMTP is a clear text protocol, so you can technically inject information into it like client source address, but the mechanisms don't natively exist in the BIG-IP to do this. You'd need to create an SMTP proxy iRule (and there are few on DevCentral).
