    Hello,

    thanks for your solutions. We have a similar problem. When we activate SNI support we get certificate errors. According to the mail client the principal name or common name does not match the certificate. For this the global hostname of the mail server is used instead of the customer domain. Is there a workarround until Kolab Premium Mail supports the SNI Support?

    Hello @Yannick Nesselhauf,

    I would like to clarify that Plesk Premium Mail is yet to support SNI on IMAP.
    As a workaround, consider using POP3 protocol.

    Hello Felipe Martini,

    Version 16.12.x is newer that 16.3.x.

    Currently, no workaround available. The issue is to be resolved on the extension authors' side.
