I wrote the code that uses Net/SMTP/TLS/ButMaintained.pm a very long time ago, before Net::SMTP included support for TLS and SSL. I have rewritten my code to use Net::SMTP.
As I am not using Net/SMTP/TLS/ButMaintained.pm, the aborted attempt to reload Net/SSLeay.pm is no longer an issue for me.
So, I am currently no longer looking out for replies to this topic or to Compilation is failing for Net::SMTP::TLS::ButMaintained with perl 5.36 build on Windows.
That leaves Unusable Perl 5.36 build - compilation failures due to various dll files not loading still requiring resolution.
