Hi.

You can try increase process_limit or switch login to performance mode:

Code: [Select]

service imap-login {
  inet_listener imap {
    port        = 143
  }
  service_count = 0 # performance mode. set to 1 for secure mode
  process_min_avail = 1
}

thanks, that should solve one problem, but what about the time?

Hi.

I couldn't reproduce the issue, and it works great in the default version.
Try to check your "Kaspersky Security for Mail Server" becuse it is not CWP's service.
