Oof, this is really tough. I'm really surprised the UID is hard-coded
like that. Are you seriously locked into using exim?
(I'm guessing yes).

I'm thinking this might be your way out. If the containers were running
as root on the host, there would be a security benefit to non-root
container users. However, since you're running rootless, you're really
not gaining anything at all (besides maybe frustration).
So, since you're hard-coded into uid 93 for exim, can you rearrange all
your non-exim containers to run as root (still rootless on the host) but
retain access the volume data that's needed?
Another idea is to have all your non-exim containers run with
`--userns:container:<Exim Container>` to help coordinate access to your
volume data. That should also reduce the amount of fiddling you need to
do with UIDs/GIDs. Everything can simply be locked into whatever is
setup in the exim container.
