=== Fixed sending slow problem on dovecot and exim on directadmin
issue: delay around 20second when sending email via webmail roundcube
===== /etc/dovecot/conf/lmtp.conf
# LMTP socket for local delivery from exim
service lmtp {
executable = lmtp -L
process_min_avail = 32
unix_listener lmtp-client {
user = mail
group = mail
mode = 0660
}
}
===== /etc/dovecot/dovecot.conf
service imap-login {
process_min_avail = 32
user = dovecot
}
service pop3-login {
process_min_avail = 32
user = dovecot
}
==Increase process_min_avail from 16 -> 32 on both configure file then restart service
systemctl restart dovecot
test send email and use 1 sec for sending process
