Were you able to get a packet dump to see if the delay is at the Google or ColdFusion ends ?

No. But we didn't have a problem getting mail until we updated to U16. If you run that test code against the same Google acccount, U16 takes a very long time but U13 doesn't. That tells me it's a CF issue. I'm guessing there was some change where CF is downloading the attachment(s) even though it shouldn't since it should "getHeaderOnly".

Looks like it is broken after Update 13, we will get this fixed in the subsequent updates.

This bug is not listed as fixed in the recent ColdFusion 11 update 7 ( Is this really not fixed in CF11?
