I have tried to replace Sylpheed's ssleay32.dll with the new
libssl-3.dll downloaded from Shining Light Productions[1]
(preserving the original file name), but Sylpheed complained
that it could not find the function
SSL_get_peer_certificate.  A glance at the manual says that
it was deprected:

  https://www.openssl.org/docs/man3.0/man3/SSL_get1_peer_certificate.html

Sylpheed has to be rebuild with a newer OpenSSL...
