Centos 6.8 Postfix 2.6.6
I still am having problems with Postgrey greylisting. I forgot my Dropbox password so I followed the know procedure. Dropbox sent me a mail to change it. Postgrey is continuously rejecting dropbox retries.
In my maillog each 5/6 minutes I see dropbox rejections, "reason=new"
I guess this is because sender's IP changes. After 4/5 tries dropbox server stops retries.
How can this be fixed apart of manually add sender in whitelist?
Edit 1: I added "dropbox.com" to /etc/postfix/postgrey_whitelist_clients.local, restarted Postfix but email@example.com is rejected (sender's "name" changes every try)
