Subject: Include check_rfc2047_length in configure.default to raise the visibility
X-Git-Tag: exim-4_73_RC0~66
X-Git-Url: https://vcs.fsf.org/?a=commitdiff_plain;h=6901c5962fbad16ca6010db5a3efd4bd8993125a;p=exim.git

Include check_rfc2047_length in configure.default to raise the visibility
because we're seeing more Russian administrators get bitten by this.

Idealism says this option is set correctly by default.  Pragmatism says not.
There's a good argument for the idealism but if we see the problems escalate
then the idealism will have lost and we should, IMO, switch.
