[Bug 1828810] Re: no dane support

[Andreas Hasenack]

Thanks for filing this bug in Ubuntu.

This does sound like an interesting feature to have. For reference, the
changes between 4.90 and 4.92 can be seen here:
https://github.com/Exim/exim/blob/master/src/README.UPDATING

The SRU policy permits such an update to a stable release, but we will
have to balance the risk and the amount of work needed.

I'll accept the bug, and put it in our backlog, but we don't have an
estimate for this. Any help would be welcomed, of course. In particular,
filing out the SRU template
https://wiki.ubuntu.com/StableReleaseUpdates#SRU_Bug_Template for this
bug. Having a good test case, and solid arguments for this update, will
go a long way.

I'll also mark this as fix released for cosmic, disco and eoan. I
couldn't find a trivial way to check if exim was built with dane
support, but ldd in the exim main binary seems good enough. It shows the
binary linked with libgnutls-dane on cosmic and later, but not on
bionic.
