Greylisting and trusted senders

Question asked by E. Keith Dodd - 8/14/2014 at 7:25 AM

Answered

I am considering starting greylisting to combat spam. I provide for a wide range of domains so need to have things flexible. I realize there can be global exclusions to greylisting, say for ebay, Amazon, etc.

However, I seem to find conflicting answers as whether a specific users (or domains) general whitelist/trusted senders for ignoring spam checks does or does not bypass greylisting. IE: If john@mydomain.com is in my own trusted sender list and when that sender sends is his mail subject to greylisting procedures or not -- is the first mail delayed or does it come right through? I know that "trusted" bypasses spam checking, but unclear about this same list for greylisting.

Appreciate any clarification. Thanks

Keith

You should have Grey listing on for all domains. Then Enable users to override greylisting , They can Use Trusted sender to bypass all checks, yes Greylisting also.

Skipping spam filtering: Trusted Sender (system level)

System administrators should note that the following cases are exempt from greylisting:

Whitelisted IPs for SMTP or Greylisting
Anyone who authenticates (includes SMTP Auth Bypass list)
Trusted senders
Anyone who has already sent you an email
Any IP in the greylistBypass.xml file

Hate to sound dense on this, but want to absolutely sure I have it right:

You are confirming that if joe@domain.com is on my personal account's Trusted Senders list, then any mail from this joe@ will not go through any greylisting procedures just like it does not go through any spam checks: right?

Thanks much! This seems about the only way to really get a stop on all this spam. I have seen a major increase in just the last few days.
