Negotiation failed with Ipad after upgrade

[Paul van der Vlis]

Hello,

I have upgraded a server from version 2.4.17 to 2.5.10 (Debian
packages), and now an Ipad does not work anymore. The error is something
like:

Jun 13 21:18:18 hostname cyrus/imap[10664]: STARTTLS negotiation failed:
host.domain.nl [1.2.3.4]

No problem with Thunderbird and Android devices, they work fine.

I've also tested imaps, but the same problem there.

In imapd.conf I have this setting:
tls_ciphers: TLSv1.2:+TLSv1:+HIGH:!aNULL:@STRENGTH

In the old version I had this setting:
tls_cipher_list: TLSv1+HIGH:!aNULL:@STRENGTH

What will be wrong?

With regards,
Paul van der Vlis
