Re: Stray newlines problem with yahoo - any solutions for this now?

Yahoo complains on a stray newline - said to be a bare LF without an accompanying CR by RFC822 standard but I didn't check that out. Anyway I put this in my body_checks:
/[^\r]\n[^\r]/ Warning Bare LF in body
and this part works. What surprised me is it gets detected regardless of message encoding. Then I tried sending these sort of messages to yahoo and yahoo didn't reject them for last two days. I am not sure if they changed something on their side but the thing is when yahoo did reject a few days ago it did it softly. A message rejected from its first attempt to transmit might get through in a subsequent attempt. For those eventually failing to be transmitted the sender gets a notification as I showed in my previous postings.
I am interested in commercial content filters because my company has one Trend Interscan VirusWall with eManager. I just haven't figured out how to have it fully implemented with my postfix. At the moment I only use it for scanning messages in and out of my postix by making it my first DNS MX and relayhost for my postfix. But I haven't really looked at the eManager package yet. I appreciate any advise from those who are experienced with it.

Thanks,
Daniel
