I've checked them. They are far away from compliance to all RFC I've listed. :( So, my question is still actual: is there exists realization compliant to all (or most) listed RFCs?

Well, as I said, I'm pretty sure that's pretty well all of the email modules on CPAN. So if they don't come up to your high standards, then it looks like you're out of luck.

Or... here's a wild and crazy idea. If you have specific areas where you know the existing modules have problems, then why not get involved with the Perl Email Project and help them fix those problems. Your involvement could be as small as raising bugs against the existing modules pointing out their deficiencies, or perhaps you could go as far as creating test cases that demonstrate the problems, or maybe you could even produce patches that fix them.

Just saying that there are problems, doesn't really achieve much. Documenting the problems and helping to fix them benefits everyone.
