This has been a normal format since 1993 or so (RFC 1522, now RFC 2047).

Everyone just stop using that unmaintained (for almost 20 years) pile of
design garbage called procmail.
Procmail wasn't palatable in 1990, and isn't in 2020.

reformime (part of maildrop) can help with decoding, but I do not know
if it would do character set conversions into the current locale.

Also someone tell Ubuntu to update fetchmail to at least 6.4.4 everywhere...
