At the bottom of each page on wikisource is written:
Content is available under CC BY-SA 3.0 unless otherwise noted.
So basically, works under a different free license should be simply come with a statement
in the page that reproduce them.
So for the exposed goal of archiving communications, there is really no big deal. Problem
might only arise if we try to mix different pages up. If CC is indeed forward compatible,
then mixing 3.0 and 4.0 licensed works should make the result only available under 4.0.
More subtle, but still not a blocker.
Cheers

(so
the problem is the version number) The argument
is, that CC licenses
are
"forward compatible" but not
"retro compatible". So it is OK to put
CC BY
3.0 material into CC BY 4.0 repository, but not
the opposite.
In the meantime I have found, that another Wikisources are collecting
materials under CC BY 4.0, like
https://en.wikisource.org/wiki/Category:CC_attribution_4.0
Note that Wikipedia uses many images under a variety of licenses,
including
CC BY 4.0 and fair use. An entire Wikipedia is not covered under any
single
license. Likewise, an entire Wikisource is not covered under a single
license;
https://en.wikisource.org/wiki/The_Grant_Shapps_Affair_Is_a_Testament_to_Wi…
is covered under the CC-BY-4.0 independently of any license the rest of
Wikisource is covered by. It's mere aggregation, not making a
derivative
work.
