Probably, but I don't think it's worth the hassle. You can do it more
easily and much more flexible with Exim's ACLs, so there's no good to
code this in the main C code.

sure, just use
warn
condition = ${lookup sqlite {delete from bla where ...}}
but that's not really needed for _every_ connection. running this once a
hour or day should be sufficient.

You have the full power of Exim's ACL, you'll hardly get something better.

I'm using spamd but I don't know what a "spam deferral daemon" is.
