2011 email router digital signature problem RRS feed

  • Question

  • Hi,

    We're running 2011 on premise with the email router feeding a queue for service items.

    We've recently seen a number of emails that hit the mail box but don't ever get processed by the email router. There are no errors in the event logs that we can see, it just seems to ignore them.

    What we are noticing though is that the emails that get missed have digital signatures on them.

    Has anyone come across this before? There doesn't appear to be anything about this is any of the documentation that we can see.

    I've searched high and low for any information on this but I've drawn a blank everywhere.

    Thanks in advance.

  • Hi,

    my guess is that it could be due to email is not send directly to primary SMTP which is configured in email router for your queue, it could be possible this email is send to other alias and if this is the case CRM ignores those email.

    for e.g. here is how you mail box is set up

            support@yourcompanyname.com  (mail box, primary SMTP, configured as queue in CRM to send recieve mail )

            service@yourcompany.com (alias for above mailbox)

    so if email is send to "service@yourcompany.com" it will be received in outlook mail box but CRM will not pick it as it does not have any matching queue set up for this.

  • I thought that might be the case too, however I've checked the smtp headers on emails that have been missed and they are sent to a single recipient which totally matches the email address, it's not like they are going through an alias or redirect or anything more complicated.

    I've had a colleague let me know that he'd heard the email router cannot process signed emails at all. If this is the case, anyone got an idea for a work around? The only thing I could think is to get Exchange to strip the signature off (if this is even possible), I tried to see if there was a way to create a rule in OWA that would forward a copy on to a different email address if it is signed but I can't see any possible rule entries that mention signatures at all.
