This bug was fixed in the package exim4 - 4.96-3ubuntu1

---------------
exim4 (4.96-3ubuntu1) kinetic; urgency=medium

  * Merge with Debian unstable. (LP: #1971274) Remaining changes:
    - Show Ubuntu distribution in SMTP banner
      + d/p/fix_smtp_banner.patch: Show Ubuntu distribution
        in SMTP banner.
      + Build-Depends on lsb-release to detect Distribution.
    - Disable external SPF support to avoid Build-Depends on libspf2-dev
      (only available in universe). SPF can still be implemented via
      spf-tools-perl, as documented in exim4.conf.template. (LP #1952738)
      This reverts Vcs-Git commit 494f1fe, first released in 4.95~RC0-1.
      Changes:
       + d/control: drop Build-Depends on libspf2-dev.
       + d/d/c/a/30_exim4-config_check_rcpt: restore SPF logic based
         on spfquery.mail-spf-perl from spf-tools-perl.
       + d/EDITME.exim4-heavy.diff: disable support for libspf2.
