are treated as format placeholders
Hi,
When I receive (Exim 4.75) messages that have a DKIM signature that
has a percentage sign in the identity field I get paniclog entries
like this:
"""
2011-04-29 04:20:53 1QFdK8-0000hi-Ts string_format: unsupported type
in "%i" in "DKIM: d=iecc.com s=4330.4db9faa9.k1104 c=simple/simple
a=rsa-sha256 i=spamfighter%iecc.com@??? [verification
succeeded]"
"""
Example headers (these reproduce the problem, but the identity field
was added to a different signature. The paniclog line above is from a
real message).
