ok we have looked all over for this and it is driving me nuts, maybe someone can help..ok I have a blackberry it has a enterprise with lotus notes from a client and we have exchange at our office which I also get on my handheld, now here is the prob we were on exchange 2003 and the guys at office upgraded to 2007 well ever since if I send an email from my handheld from the exchange email I get a delivery conformation, from every email I send, if I send from web interface it does not do it, if I send from my handheld to XXXXXX@email.com then the delivery conformation comes from postmaster@email.com if I would send to XXXXX@google.com then the delivery conf. comes from postmaster@google.com. so it is as exchange is asking each recipient for a delivery conformation, well i have looked on the server side in settings and I have looked at my blackberry account set up and I have looked at exchange web interface and I do not see where this is coming from, I read something on plain text and html so I went and changed from html to plain text but no change, still getting delivery conformations. was anything changed from 2003 to 2007 that is making it do this? thanks for any help
