Hi,

since they are fucking too stupid for SPF on their subdomains
whitelist_from_rcvd *@pm.sprint.com sprintpcs.com

all headers begin with x- is pr defination forged header


when there is no SPF/DKIM you need to rely on headers

omg, both of you guys. I didn't say anything about SPF

i know that - see my frist reply

I realize
there's no SPF/DKIM, and in fact already stated that. I'm trying to
get even the most basic form of whitelisting working.

whitelist_from *@pm.sprintpcs.com

does not work.. Why?

maybe because they are just idiots and the from-header is invalid?
From: 5556142...@pm.sprint.com

there are no <>

anyways, you are talking a lot that you have tried several things without mention *what* you tried

whitelist_from_rcvd *@pm.sprint.com sprintpcs.com

RTFM:
"whitelist_from_rcvd" hangs on the sender and reverse-dns

X-Envelope-From: <15556142...@pm.sprint.com>
X-Spam-RelaysUntrusted: [ ip=66.1.208.13 rdns=smtp4a.mo.sprintpcs.com

when that don't work blame the sender for a) invalid headers and b) using SPF for "sprint.com" but not for "pm.sprint.com"
