Subject: [exim] Exim4 vs Gmail - DKIM algorithms incompatibility
Dear All,

I am facing problem in DKIM Signing for Gmail, rest all domins verify its very vell.

I google so many forums & found that its resolved in newer version of Exim. But still i face DKIM fail in gmail.com

I installed it on CentOs 6 & tried following exim versions for this.

exim-4.80.1-49.el6.x86_64.rpm
exim-4.82-1.el6.denf.x86_64.rpm
exim-4.84-4iv.el6.x86_64.rpm

My Exim configuration is as follows.
DKIM_DOMAIN = ${lc:${domain:$h_from:}}

dkim_domain = DKIM_DOMAIN
dkim_selector = selector
dkim_private_key = /etc/exim/private.key
dkim_canon = relaxed

Here is the Header of that mail
