[Dovecot] iphone connection problem

[dovecot at feb17.org]

One more piece of info for comparison, here's the thunderbrid ssldump. I'm not sure
what the application_data is but it's received happily here

The iphone seems to get upset at around this point and raise
an alert which leads to the server closing the connection after
raising its own alert.  I don't seem to be able to get any more information
on the nature of the complaint unfortunately.  I've tried providing the ssl key
to ssldump but it doesn't reveal anything,
