McGrail <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|NEW |RESOLVED Resolution| |INVALID --- Comment #12 from Kevin A. McGrail <[email protected]> 2012-01-16 22:53:20 UTC --- The attached patch changed behavior in Sendmail that can modify the To header that is received from the sender AFTER the message has been DKIM signed. This behavior can cause issues in situations such as using Gmail to send to a recipient using gmail where the To: address uses mixed case letters causing DKIM after receipt to fail. This patch from Claus Aßmann will be included in the next sendmail release and was tested on Sendmail 8.14.5. I believe this resolves the issue unless more samples are produced that show it isn't a To: Case issue. For those who don't want to patch/install their own sendmail, the nocanonify feature has helped eliminate the issue in real-world environments as well but is likely doing other things that may cause issues. i.e. submit.mc and sendmail.mc including: FEATURE(`nocanonify',`canonify_hosts') Closing as invalid as likely a configuration/bug in MTA. regards, KAM -- Configure bugmail: https://issues.apache.org/SpamAssassin/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug.
