    Sending e-mails from Gmail to and IDN-address on cPanel has stopped working (from version 70?).
    No recent changes has been made to DNS (hosted elsewhere).

    From cPanel Mail Delivery Reports:
    Code:

    [B]Result[/B]: The mail server could not deliver mail to [EMAIL]user@domainwithnationalcharacters.se[/EMAIL]. The account or domain may not exist, they may be blacklisted, or missing the proper dns entries.
    
    Any ideas?

    Thanks!

    Hello @Zackarias Holtelius,

    Can you verify which version of cPanel & WHM is installed on this system? EX:

    Code:
    cat /usr/local/cpanel/version
    cPanel & WHM version 70.0.44 is now published to the CURRENT and RELEASE release tiers and includes a case that disables SMTPUTF8:

    Fixed case CPANEL-20542: Explicitly disable SMTPUTF8.

    Upon updating to this version, run the following commands to ensure the change is enabled and verify if it solves the problem you are facing:

    Code:
    /scripts/buildeximconf
    /scripts/restartsrv_exim
    Prior to this, cPanel & WHM version 70.0.41 included a change that enabled SMTPUTF8 support with Exim, thus potentially leading to the issue you described.

    Thank you.

    Version 70.0.44 is installed.

    Works like a charm after running buildeximconf and restartsrv_exim! E-mails are now getting through to the IDN-domain addresses.

    Thanks!
