Hi,

During a rebuild of all packages in sid, your package failed to build
on amd64.

Relevant part (hopefully):
> make[1]: Entering directory '/<<PKGBUILDDIR>>'
> DESTDIR=/<<PKGBUILDDIR>>/debian/proftpd-mod-dnsbl prxs -c mod_dnsbl.c
> Cannot compile mod_dnsbl using prxs; use existing ./configure script instead:
> 
>   ./configure
>   make
>   make install
> make[1]: *** [debian/rules:15: override_dh_auto_build] Error 1

The full build log is available from:
   http://qa-logs.debian.net/2020/12/26/proftpd-mod-dnsbl_0.1.5-5_unstable.log

A list of current common problems and possible solutions is available at
http://wiki.debian.org/qa.debian.org/FTBFS . You're welcome to contribute!

If you reassign this bug to another package, please marking it as 'affects'-ing
this package. See https://www.debian.org/Bugs/server-control#affects

If you fail to reproduce this, please provide a build log and diff it with me
so that we can identify if something relevant changed in the meantime.

About the archive rebuild: The rebuild was done on EC2 VM instances from
Amazon Web Services, using a clean, minimal and up-to-date chroot. Every
failed build was retried once to eliminate random failures.
