Hello to everybody,
yesterday I change my public IP address (i changed provider) and since then all email is received in the spam folder.

I looked in the settings to see if there was anything to change but I couldn’t find anything.

Is there something that I should do to fix the problem?

Thanks in advance

Matteo

Hello,

Have you (your provider) set the reverse DNS record for the IP address?

3

…or are these incoming our outgoing emails?

This is incoming mail, I set up the reverse DNS this morning but nothing has changed and external emails continue to be directed to the junk mail folder.

Is there anything else that I can try?

Please share the headers of a message ended in the Junk folder. Additional information can help us to help you!

For example one of mine has the X-Spamd-Result header, with spam score details:

Hi @Mat.78 ,

Please check if DNS is working properly.

Let’s try to get an MX record:

[root@server2 ~]# dig +short MX google.com
10 smtp.google.com.

Check out this wiki page about general requirements for running mail servers.

Hi MrMarkuz,
I was on holiday and I came back yesterday.

I’ve tried your solution but it doesn’t work (MX record was set correctly):

% dig +short MX domain.it
70 mail.domain.it.
70 server.domain.it.

On the wiki page you pointed me to I see this instructions:

set MX record YourDnsProvider

What is YourDNSProvider?

I check my server with https://www.mail-tester.com/ and it’s perfect (10/10)

I check my reverse DNS and it’s correct

What else can I do?

Why are there 2 entries? Do you use 2 mail servers?

Usually you use a DNS provider where you can setup DNS entries.
