we have never had issues with Yahoo Groups, which may be a good thing.

However, we seem to be getting more and more complaints that 452 
temporary greylist embargo errors are being returned to senders as 
"undeliverable".  I've had to turn off greylisting until we can figure 
out what legitimate mail was never delivered.   First step is to figure 
out what MTAs these folks are using and why are they receiving the mail 
returned and not queued.
