Re: [Dovecot] "dovecot: Maximum number of mail processes exceeded"

Hi Ralf,

At noon, I often get "dovecot: Maximum number of mail processes exceeded"

I'm at my wits end, which parameter needs to be increased further?

You have to increase "max_mail_processes" as this code emits the error message:

    if (mail_process_count == set->max_mail_processes) {
            i_error("Maximum number of mail processes exceeded");
            return MASTER_LOGIN_STATUS_INTERNAL_ERROR;
    }

[...]

max_mail_processes: 1024 [...]

But the question is: how much user are accessing your server simultaneously? Is it really more than 1024 or is mail_process_count wrong? Your overpowered server is surely able to handle more than 1024 connections.
