Issue: I wanted to hide the EXIM version number in order to avoid malicious
email scanners to get information from EXIM.
Bug: I removed the ${version_number} part on WHM>EXIM Configuration
Manager>Advanced Editor>smtp_banner and rebooted EXIM. Funilly enough, the
sent emails [u]were still showing EXIM's version in their headers[/u].
Solution: remove the line ESMTP Exim \#${compile_number} ${tod_full} from
the EXIM configuration file. That did the trick and now sent emails have
not anymore information about EXIM's version.
Please, could you check if this is a bug, or perhaps I am missing
something? Ideally, when we change the smtp_banner field, it must change
the sent emails' headers, without need to delete anything in the EXIM
configuration file.
