Hi,

I use greylisting but some services send an email code that I have to enter within a short time but when greylisting is enabled I recieve the message to late.
Is there a way to have a kind of welcomelist that makes it possible to bypass greylisting ?
Or any option to make the greylisting feature faster ?
 
Hi @Rene72

thanks for posting on the forum!

You can disable greylisting and all other SMTP checks by adding the sender to the SMTP welcomelist [1].
This should only be done for trusted sources.

Additionally mentioned, greylisting should only delay the first delivery of a new email contact and will store the known sender in a table as documented here [2].
So if you frequently receive mails from the same sender network they shouldn't be greylisted anymore.

Best regards
Jonas
