Problem receiving email unless on wifi

[Beverly Stone]

All of a sudden we can no longer receive email on our phone unless on wifi. We have changed no settings. For years we were able to get it anywhere but no longer. We can send, but not receive. Help, please!

This is probably something about your cell provider.

To get help, you will need to explain all the details:
k-9 version
type: imap-ssl, pop, and so on. and port
provider
cell carrier
when you push the sync button, what happens?

which of "we" has differences above (if there are 4 of you and it's
across 3 carriers, that's relevant)

Then, you probably should use adb logcat to see what k-9 is saying. I
realize that may be hard but I think it is what will explain things.


It might be nice for k-9 to have the equivalent of mac mail's
"connection doctor". Basically try to make outgoing and incoming
connections, show green dot if it happens, and red dot and error message
if not.
