email errors log

Beitrag von tom83 » Fr 13. Dez 2019, 14:13

Hi,

I'm using KeyHelp and the DNS are on CloudFlare. In general seems to be working but I'm having some email errors on log, for example:

Code: Alles auswählen

host vip-us-br-mx.terra.com[208.84.244.133] refused to talk to me: 554 mail-cmgw10-mia.tpn.terra.com cmsmtp Client host rejected: cannot find your hostname 149.28.46.132

Code: Alles auswählen

host mx-vip-01-farm74.uni5.net[177.185.202.35] said: 450 4.7.25 Client host rejected: cannot find your hostname, [149.28.46.132] (in reply to RCPT TO command)

Code: Alles auswählen

host mail.agricultura.gov.br[201.57.198.136] refused to talk to me: 554 5.7.1 Delivery not authorized
What's the best practice to configure reverse DNS, PTR, etc and how to do it right?

And is there any place to check logs for all IN and OUT emails? Or should be manual using command line?

Thanks people!

I am currently only using my cell phone. But if I remember correctly, I read somewhere: Do not use CF for mail servers.
The software said: Requires Win Vista®, 7®, 8® or better. And so I installed Linux.

Hello,

Cloudflare can not be used as cache for mail. It is a chache for websites. Of course you can use Cloudflare with Keyhelp for website and mail. Turn of the DNS settings in Keyhelp for the Domain.

With Cloudflare you can't use the dns of Keyhelp. You must use the DNS from Cloudflare. Point your MX settings in Cloudflare to your mailserver and then the A record for “mail.domain.com” must have a “grey-cloud” icon next to the DNS A record.

There are more settings to do. What have you done yet?
