hello.
> A - Verify MAIL FROM address
the simple verify is no longer usable, as more and more servers disable it.
there is a new smtp message 252 "try sending" "valid email adresse foprmat"
or similar text. (i guess imail does not a complete mail from: and rcpt to:
cycle to determin a valid sender?
> B - Perform reverse DNS lookup for connecting server
this will always fail for a mailserver connected to a dynamic ip-adress pool
like most dsl-providers (at least in germany) use.
bye.
