Hello there,

I'm using DNS-CACHE service with PMTA and I have the following configuration in pmta file.

Code: [Select]



<dns>   
precached-domains-file /etc/pmta/precached-domains
precached-max-domains 500     
precached-refresh-interval 5m
</dns>


Could you please tell me why we can't reach a lot of corporate emails? Someone have some experience with this DNS service? Some configuration or favorite DNS provider?

Thank you!

What is the DNS TTL for the domains in question?  The feature still uses the TTL to determine when to look up the domain again.  A really short TTL may cause issues as we are constantly having to look it up.

Hello Admin, thanks for your reply.

Do you reffer TTL of domain to send?

When I do a dig -t mx to domain.com, the DNS resolution given is

Code: [Select]

;; connection timed out; no servers could be reached
But if I change to dig @8.8.8.8 -t mx domain.com the DNS resolutions is ok.

So, I change the resolv.conf adding 8.8.8.8 as secundary DNS.

Do you recommend this? Do I to restart pmta? Do you have some additional advice ?

Thank you!

Sure, just add the following globally:

name-server 8.8.8.8
name-server 8.8.4.4

Once added, reload PowerMTA with "pmta reload"
