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?
