[qmailtoaster] CHKUSER rejecting mail from amazon

[Josh Dinsdale]

Hi Guys   For some reason chkuser is rejecting a lot of mail from amazon, heres a snippet from my smtp log:   CHKUSER rejected sender: from <[EMAIL PROTECTED]::> remote <mail-store-0101.amazon.com:unknown:207.171.180.180> rcpt <> : invalid sender address format   CHKUSER rejected sender: from <[EMAIL PROTECTED]::> remote <mm-notify-out-12101.amazon.com:unknown:87.238.85.54> rcpt <> : invalid sender address format   I’ve got hundreds of these in my logs.   Anyone know why this is happening and how I can resolve it?
