Hi all,
  I asked a question regarding 
email delays a few months ago, and I think I found a workaround.  I changed our 
email from "
[email protected]" to "
[email protected]", and it seems to work instantly again.  
After reading some articles, I believe this could be due to some form of greylisting, though some servers might call it something else -- if a server like yahoo or gmail receive 
email from a server that it is not used to receiving 
email from, then sometimes the delay occurs.  But a name such as yahoo, gmail, which requires a user to sign up manually -- this delay can be avoided.  
My question is this: does anyone know more about this issue -- especially since it would be nice to send an 
email from our own site, instead of needing to use a whitelisted server?  
Thanks!
