@dahalday,

I’d be happy to assist you getting things working, drop me a line and let’s discuss. As you are a “Pro” user, you can also shout out to @staff for assistance if you’d prefer their assistance. Between the 5 of us (VM Team + Me) I’m certain we can get things working for you.

As a tip, few things to pay attention to:

Double check that package libsasl2-modules is installed

Restarting the following services should not produce any errors:

systemctl restart saslauthd
systemctl restart postfix
systemctl restart dovecot

Your IP is not blocked by fail2ban service

Thank you everyone

This is what worked so far

https://www.howtoforge.com/community/threads/changing-from-mbox-to-maildir-after-installing-ispconfig.4162/

Also ensure

Procmail Mail Filter

Action to take Conditions Move Add
Set variable LOGFILE to /var/log/procmail.log
Set variable TRAP to /etc/webmin/virtual-server/procmail-logger.pl
Set variable VIRTUALMIN Always execute action
Set variable EXITCODE to $?
Append to file /dev/null Exit status of command /usr/bin/test “$EXITCODE” = “73”
Set variable EXITCODE to 0
Execute conditional block Exit status of command /usr/bin/test “$VIRTUALMIN” != “”
Set variable ORGMAIL to $HOME/Maildir/
Set variable DEFAULT to $HOME/Maildir/
Set variable DROPPRIVS to yes
Append to file $DEFAULT Always execute action

Now I am having an issue with new email mapping user-domain.com instead of user@domain.com
