dovecot - Sep 2018 - dovecot (2.2.13) panic on imap-login from iphone se

Hi to all,

we have trouble with one user account, when using imap-login with iphone
se. The user can login and use the account from webmail (roundcube) and
from thunderbird without any errors and without any restrictions.

But if we use the account on an iphone se and try to use imap based
emails, there comes the following error (look at the end of the mail).
I have no idea, what for an error it is. Same account on an iphone 5
works without any trouble.

We have delete the homedir of the user and also recreated the user with
new uid and new password. Webmail and thunderbird are fine, but if we
use the iphone se we got this error.

Are there any known issues with this combination?
Thanks for your help.

Can you upgrade to 2.2.36 or 2.3.2.1 and reproduce this issue? 2.2.13 is quite
old.
