Question asked by Lenny Estrin - March 14, 2015 at 11:08 AM

Hi,
we are using SmarterMail Professional 12.3. 
Recently alot of new spam has been trying to get in so greylisting is considered as one of measures to combat spam.
While idea of greylisting looks fine, still it would be usefull to be abel to set it in a granular fashion.
Can greylisting be set per domain/user level and how?
 
Regards,
Drazen

You can disable Greylisting per domain by Choosing the Domain > Edit > Technical > Disable Greylisting. Unsure on a per mailbox basis. Just to add, Greylisting should really be enabled... Serverwide. Remembering that any client with it disabled should pay more for their services as it will be harder on the server resources. Just my opinion though.

If you set Greylisting to block for 1 minute, then it will minimize the delay.  remember, it's only the first time a message is received from a user to local mailbox.
 
We enforce Greylisting and antispam via our contracts - no one can override.  Total enforcement has eliminated more than 70% of our support tickets, and, once they get over the initial gasp, they usually don't say another word.
 
As CCWH stated, not enforcing Greylisting makes your server and SmarterMail work a lot harder, so, if they insist on having it turned off, charge for it - and for your support time.

Did you set the times to the latest document?
 
Do you have a populated exceptions list?
 
 
 
Note the BLOCK PERIOD is set to 1 MINUTE
 
Everyone whose an MX server should be retrying now.  We see AOL, COMCAST, GMAIL and all of the other "prior offenders" now retrying several times per minute.
 
Did you also check your SMTP and DELIVERY logs to see if there are any other issues with the sending domains?
 
We've found delayed/non delivery issues caused when a sender has multiple MX servers and one, or more, of them are not "available." 
 
While that should not be causing issues, and messages should be automatically retried by senders, we both know that there are still many who are not in compliance.
