Hello, Any ideia to solve this one? php app/console mautic:fetch:email 0 emails processed for {xx.xxxx.xx:993/imap/ssl/novalidate-cert}INBOX\_email PHP Notice: Unknown: Kerberos error: No Kerberos credentials available (try running kinit) for xx.xxx.xx (errflg=1) in Unknown on line 0 In other applications, i now that in SMTP is possible to add the flag to disable the GSSAPI auth, any ideia on Mautic to do the same? The Exchange don’t have kerberos auth enable. Kind Regards, Tiago Reis ---
