[Greylist-users] Proper format for a tempfail?

Most likely their server just never retries and you will have to whitelist 
them. We ran into quite a number of servers that did NO retires at all. If 
our mail server or connection was down (with or without greylisting) we 
would have missed the mail as well.  If other servers are accepting your 
temp fail and retrying, then I would say the format would be acceptable.  
Just whitelist this domain and IP or to/from/ip triplets as you see them 
fail if there are not that many.
