if I send an email from an iPAD(with Datasync 1.2.3 and ZMM 2.5 to GW2012) the mail comes with a wrong from: address-format like userid.PostOffice.Domain@internetdomain. If I send an email with the groupwise-client or with Webacc all works fine.
Receiving of mails to: userid@internetdomain works also without problems.

Any hints ?

Thank you, Heiko
