   iCloud Not Receiving Mail Reliably from Gmail

   Adam C. Engst

   File this one under the 'nice to know but not much to be done about it'
   category. Over the past week, we and many other iCloud and Gmail users
   have started to notice that some, but not all, messages from Gmail to
   iCloud have been delayed, sometimes for days, or even rejected after
   too much time has passed. A number of threads at Apple Support
   Communities (such as [1]this one) have talked through all the
   variables, and it simply seems that there's something deep within the
   guts of iCloud that is having trouble receiving mail from Gmail. Some
   people have commented that email delivery from other services seems to
   be affected as well, but we haven't yet been able to track down any
   patterns there.

   The [2]Apple Services, Stores, and iCloud status page makes no mention
   of the problem; it's conceivable that these issues are related to the
   all-day [3]Apple service outage on 11 March 2015.

   As I noted, there doesn't seem to be any way to work around this
   problem. Neither Gmail nor iCloud offer users any insight into or much
   control over their inner workings, so we'll just have to wait and let
   Apple's and Google's email administrators figure out and solve the
   problem.

   In the meantime, if you have a non-iCloud email address, it would be
   worth telling your Gmail-based correspondents to use it instead. And if
   you forward your Gmail account to iCloud, consider logging in to Gmail
   directly to check mail there until this is resolved.
