Question Dovecot - error messages

MartinB

Basic Pleskian
Hello !

I hope you can help me ... ;)

Yesterday morning, I want to log in at my webmailer Roundcube ...
... but I can't : no connection to server ! :eek:

Here are some lines from the logfile :

Code:

After restart Dovecot anything is okay !

Are special settings needed ?

Thanks for any tips ... :)


Bye, Martin
 
  1. Create a file /etc/dovecot/conf.d/99-imap-login.conf with the following content:

    service imap-login {
    process_limit = 200
    process_min_avail = 16
    }

  2. Tune process_limit value according to the server load.
