According to bug #82265 (and old unused lines from the ebuild), mixmaster use-flag used to be incompatible with nntp patch but this does not seem true anymore. Could this use-flag be re-enabled please ? related: bug #80717 (reenabling of mixmaster in 2005) Reproducible: Always
mutt-1.5.23-r1 has mixmaster unconditionally enabled now, thanks!
