It was thus said that the Great william degnan once stated:
I have found that bounces can be reduced if you play
around with the
receiving mail server. For example, turn off greylisting (returns 400
level codes some servers don't like).
I do greylisting on my email server [1] and I have no problems with this
list. I do have a delay of 25 minutes though. And currently, the following
have been whitelisted (classiccmp.org survived the timeout period):
199.188.211.196 cctalk-bounces at classiccmp.org spc at conman.org
199.188.211.196 cctech-bounces at classiccmp.org spc at conman.org
199.188.211.196 mailman-bounces at classiccmp.org spc at conman.org
