Mail Proxy - White list problem

[Goldy]

Hi everybody.
If I understand correctly, all entries in the 'Mail Proxy - Whitelist' should bypass spam checks. However, I’ve noticed that some domains or email addresses I’ve added there are still being flagged as spam. Any ideas on how to resolve this?

You are describing the SMTP whitelist. Here, certain checks are only deactivated in the SMTP dialog, i.e. when the mail is received. For example, greylisting, SPF check & DSNBL checks for the sender or the domain you have specified.

If you want to ensure that senders or domains are provided without a flag, you must also create a rule under Mail Filter and set the sender/domain to Accept. These rules only take effect after the mail has been accepted and processed by Spamassassin.

Hi.
Thanks.
Although both the email address and domain are whitelisted under Mail filter-Who Object-Whitelist, they are still being marked as spam and sent to quarantine.

Could you post screenshots of your config and possibly a log of a whitelisted email?

Thanks...

Have you applied the rule accordingly? In the places in your screenshots, you only create them for the time being, so they are not yet applied:



Please also provide a log of a whitelisted e-mail that is declared as spam.

Not sure where to find log of a whitelisted email.
See if the attached file help.

You can find the log in the same place, we only need the log from a sender on the whitelist, which is nevertheless blocked.

It is clear from the log that your query is being blocked by Spamhaus:

URIBL_DBL_BLOCKED_OPENDNS 0.001 ADMINISTRATOR NOTICE: The query to dbl.spamhaus.org was blocked due to usage of an open resolver. See https://www.spamhaus.org/returnc/pub/ [Commax.com,u2274819.ct.sendgrid.net]

This is because your PMG uses a DNS server that is blocked by Spamhaus. Many RBLs block public DNS resolvers. It could also be that PMG flagged the mail as spam because it could not reach the RBL.
