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:
https://10.18.5.15:2087/cpsess1914789137/scripts/command?PFILE=main
"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.
