    I have a spam issue where by emails are sent from non-existing addresses.

    On the server I have one info@domain.com but the spam is sending from a@domain.com, b@domain.com etc.

    I want to prevent sending email from existing emails only.

    Hello,

    May I know the exact email logs for the email sending.

    You can check the logs with the help of the URL :-

    tail -f /var/log/exim_mainlog

    Hope this helps.

    Hello,

    Do you have the headers of one of the messages, or the corresponding entry in /var/log/exim_mainlog? EX:

    Code:
    exigrep a@domain.tld /var/log/exim_mainlog
    Thank you.
