>>> I've been rolling my own fetchmail 6.4 rpm on CentOS 6, statically compiled against openssl 1.1.1. The method might work on CentOS 7 with fetchmail 7 and openssl 3.0 in a similar way. Obviously, one should update when either fetchmail or openssl release a new version.

Try cloning from Git and switch to the "next" branch. Read README.git
and install necessary maintainer tools. Also note that I do not support
building future releases on older systems even if they are under
long-term support.

I roll alpha tarballs very infrequently, however, I believe Git commit
cfa4ebceb fixes this up. All the other parts should be ready for OpenSSL 3.

- under [Options v] top right, there are ways to "Download" a patch in
two forms, or just manually remove the lines in your socket.c shown on
red background.
