I am compiling Emacs from source on Windows using MSYS2 on the environment UCRT64. When compiling emacs there is a message about emacs using as standard during the build process (at least in Windows) the POP package for mail handling which apparently uses insecure connections, it then suggests putting –without-pop on the ./configure command to remove this source of insecurity.

I don’t know if I would like to use emacs for reading emails, but I would like to build emacs to at least have the capability of such. I know that for secure email retrieval in Linux emacs uses the GNU Mailutils package, but there does not seem to be a pre-build mailutils package for UCRT (or for any other environment) on the MSYS2 repository.

Is it impossible to simply build the mailutils package from source in windows using the GNU utilities available in the URCT environment of MSYS2? Or would the build process be so long and depend on so many other non-pre-build packages that it would be unfeasible in practice?

It would be no problem for me if the build process is somewhat long, as long as it didn’t take more than 3 days to complete the build of the mailutils package in URCT. I didn’t try this yet because I could not find any posts about this, and there is the possibility of mailutils using explicitly Linux system calls or otherwise incompatible code for Windows in the source code itself, kind of like how chmod doesn’t work in MSYS2.
