Hi,
One of our clients has noticed, that when he is using our server as SMTP an interesting line appears in message header - X-PopBeforeSMTPSenders, which contains all mail accounts that this user has. Here is sample:

X-PopBeforeSMTPSenders: [email protected],[email protected],[email protected]

Server is running WHM 10.1.0 cPanel 10.2.0-R52, Fedora i686 - WHM X v3.1.0.

I asked him to use another server for SMTP and then that line is not added. Does anyone else got into this? How can I remove this line?

Thanks!
Anton.

Go on, have a guess
Yup. If you don't want it, disable it in WHM > Tweak Settings, it's only in there for problem tracking purposes and isn't enabled by default (IIRC).

Do you mean this setting: Track the origin of messages sent though the mail server by adding the X-Source headers (exim 4.34+ required) ?

I have disabled this option and restarted exim, it didn't help. :(
