Re: Zimbra 554 5.7.1 error, RCPT error
Putting aside your bank’s issue, your setup on its own will generate a lot of false positives due to your DNS checks. You also shouldn’t check zen and dbl and sbl as zen is a composite list.nikola011 wrote:Hi Guys,
This is how the mail spam filter is set
Do you have any suggestion, because the number of emails that are not arriving has escalated
Thank you very much best regards
Nikola
Take a look at https://www.missioncriticalemail.com/20 ... ices-2019/ for some setup tips.
Hope that helps,

Hi Mark,
Thanks a lot for sharing tips, this helps me a lot. Admin has changed, so I'm still learning how Zimbra works.
I will shorten the SBL, XBL and PBL blocklists to just ZEN
Apparently I have a lot of false results.
I'm still researching
Thank you very much

Hi Guys.
I found this
https://www.claudiokuenzler.com/blog/12 ... n-resolver
Are you currently using the Spamhaus Project's DNS Blocklists (DNSBLs)? Do you access them via the Public Mirrors, for example, query "sbl.spamhaus.org"? Do you use Cloudflare's DNS? If you've answered "yes" to all three of those questions, you need to make some changes to your email infrastructure. These changes are quick and easy to make, but if you fail to make them, you could find that at some point in 2022, all or none of your email is blocked!
This is a similar time when this happened to me.
