Gmail Vs. Greylisting


Recommended Posts

Hi,

 

How to correctly configure greylisting and incoming mails from gmail (and others mail servers which have random HELO domain)? Mostly, mails from gmail are delived (verified) for about 2h, many rejected actions. This makes nervous administrator and end user.

It's not possible currently becouse Google is creating own mail policy (they are huge and they think that they can do this :) ) and reply for GL request is send from 1st free mail server not from this one where GL request was send, so the only thing which You can do is add all google mail adresses to list of ignored ( ofcourse it will also pass spam )

Hi kosmito,

 

Greylisting will analyze mail sent from each unique server address. Gmail, and most other web-based email providers, use many servers to send email.

 

As Bart suggested, you can set domains or IP addresses to bypass the Greylisting. When evaluating emails, Mail Security takes into account the configurations of the Approved IP addresses list, the Ignored IP addresses list, the Safe Senders list on the Exchange server, the Allow IP list on the Exchange server, and the AntispamBypass settings for the recipient mailbox. However, this will also bypass all other Mail Security Antispam scanning.

 

Thank you,

ChadH
