    okay i found out that i have to raise my limits

    process limit 50 - anyone knows how to increase these limits ?

    doveconf -n | grep limit
    client_limit = 500
    process_limit = 50
    vsz_limit = 64 M
    process_limit = 512
    vsz_limit = 256 M
    client_limit = 500
    process_limit = 50
    vsz_limit = 64 M
    process_limit = 512
    vsz_limit = 256 M
    client_limit = 500
    process_limit = 50
    vsz_limit = 64 M
    process_limit = 512
    vsz_limit = 256 M

    solved so far - all settings can be found in

    /etc/dovecot/dovecot.conf

    i set

    doveconf -n | grep limit
    client_limit = 2000
    process_limit = 2000
    vsz_limit = 512 M
    process_limit = 2512
    vsz_limit = 2 G
    client_limit = 2000
    process_limit = 2000
    vsz_limit = 512 M
    process_limit = 2000
    vsz_limit = 2 G
    client_limit = 2000
    process_limit = 2000
    vsz_limit = 512 M
    process_limit = 2000
    vsz_limit = 2 G

    now when i restart imap inside whm i get

    May 17 13:58:38 myserver dovecot: config: Warning: service anvil { client_limit=1000 } is lower than required under max. load (4103)
    May 17 13:58:38 myserver dovecot: Warning: fd limit (ulimit -n) is lower than required under max. load (1024 < 2000), because of service pop3-login { client_limit }

    Hello,

    I recommend making changes to the mailserver configuration via Web Host Manager:

    "WHM Home » Service Configuration » Mailserver Configuration"

    Instructions on how to preserve changes made via the command line are found at:

    Configure Dovecot - Documentation - cPanel Documentation

    Thank you.
