indeed - but my signing isn't broken...
I posted this response a while ago to another query, copying now in case it's the same issue:
I had a problem a couple of years ago with Mimecast marking some DKIM-signed emails as failing, even though they passed everywhere else. After escalating the ticket several times and with a lot of insistence from us, Mimecast eventually admitted that "the cause of the issue is our limited support for 8bit encoding". At the time they said that "no ETA has been shared with us but the engineering case has been open for quite some time". I don't know if it ever got fixed, as we worked around it. Maybe that could be the same issue? Andy _______________________________________________ mailop mailing list mailop@mailop.org https://list.mailop.org/listinfo/mailop
