If you can set up a reproducer mail-from it'll be worth
comparing with debug turned on by a commandline option.
I assume by "problem goes away" you mean that such mails
are properly delivered?
Is the effect repeatable for a given seen-bad mail-from,
if you manually insert a test using "swaks"? How about
-bh and (if needed) -oMi ?

Are there definite cases not involving those characters?
Does the config have any customised (over the baseline Exim,
so including anything Debian do) name affix (prefix or suffix)
manipulation?
