    Hello,

    You should not have to manually update the Dovecot configuration for performance, so we don't publish any optimization guides for Dovecot. Could you elaborate on the specific performance issues you are experiencing with it?

    Thank you.

    No issues just want to optimize it very well and improve on what we have already :)

    What dovecot settingsin cpanel do you think will be good for say 2000 mailboxes? I'm going insane here but lets say we have 2000 mailboxes connecting every 1 minutes.

    Current settings are:

    Maximum Number of Mail Processes: 1500
    Maximum Size of a Mail Process (MB): 256
    Maximum IMAP Connections Per IP Address: 50
    Interval between IMAP IDLE “OK Still here” messages: 24
    Maximum POP3 Connections per IP Address: 50
    Number of Spare Authentication Processes: 20
    Maximum Number of Authentication Processes: 1024
    Maximum Size of a Authentication Process (MB): 128
    Size of Authentication Cache (KB): 1024
    Time to Cache Successful Logins: 3600
    Time to Cache Failed Logins: 3600
    Idle Check Interval: 30

    Hello,

    I don't see a need to make any changes unless you start to experience issues with customers failing to authenticate due to a lack of authentication processes.

    Thank you.
