Thank you

Sorry.
I rephrase the question, is there a library for sending b4j emails in which the email headers can be changed. Thanks and sorry for the inconvenience

B4J - jNet

You can add additional headers with the SMTP Object.

BUT this will not help you with your issue.

indeed. You can ignore the read request in your mail client and it can be ignored at server level for entire mail domains aswell to prevent useless traffic.
