--with-base64compat harmful

[arekm]

Issue for sake of others googling around and looking for libsrs-alt.

--with-base64compat is unfortunately recommented in README but it breaks RFC5321 compatibility.
It can generate addresses like "SRS0=GW..5e=YD=test.pl=test@example.com" where there are two
dots without any separator between and that is invalid according to above RFC.

(and for example google enforces strict RFC5321 checking and is catching that incompatibility)

make patch? But libsrs_alt is obsolete and exim already have native support of SRS internally (see https://bugs.exim.org/show_bug.cgi?id=1649).

About a patch ... not sure which character would be good to be used as replacement for 'dot'. So for now disabling base64compat option works (with its drawbacks though).

exim doesn't have "native srs support". Exim is flexible enough that you can implement SRS with its internal functions but that's nasty and error prone.
