    Hello!
    I recently began using AquaMail app on Android and now and then I get error: 'mail_max_userip_connections=10'.
    How to fix this?

    Most likely this app makes more then 10 simulatnious connections to either imap or smtp. Please take a look at the mail log and post the error that you get there to find out which service is throwing this error.

    You can increase the mail_max_userip_connections value. The default is 10.

    Where does it say that the default is 10?
    This is my /etc/dovecot/dovecot.conf file:

    In the dovecot code.

    Add:

    mail_max_userip_connections = 20

    and restart dovecot.

    Thank you.
    I was confused. I thought that the limit is configured in:
    So, if the error happens again, I just need to increase the number?

    You can trust us or run doveconf to see all settings (incl. the defaults).
