# touch /var/log/dovecot.log

# touch /var/log/dovecot-info.log

# vi /etc/dovecot.conf

add the following entries

# Remove imaps things if you don’t want them
protocols = imaps
# It’s nice to have separate log files for Dovecot. You could do this
# by changing syslog configuration also, but this is easier.
log_path = /var/log/dovecot.log
info_log_path = /var/log/dovecot-info.log
# Disable SSL for now.
ssl = no # v1.2+, for older versions use: ssl_disable = yes
disable_plaintext_auth = no
# We’re using Maildir format
mail_location = maildir:~/Maildir
# If you’re using POP3, you’ll need this:
# pop3_uidl_format = %08Xu%08Xv
# Authentication configuration:
auth_verbose = yes
auth default {
mechanisms = plain
passdb passwd-file {
args = /etc/dovecot/passwd
}
userdb static {
args = uid=vmail gid=vmail home=/home/vmail/%u
}
}

# mkdir /etc/dovecot/

# touch /etc/dovecot/passwd

# chown -R dovecot:dovecot /etc/dovecot

add the following line to

# vi /etc/dovecot/passwd

add this line:

vasanth@tetsing:{PLAIN}redhat

hemanth@testing.com:{PLAIN}redhat


save the file



Take browser

enter

localhost/webmail

username: vasanth@tetsing.com
password: redhat

You can also use

username: hemanth@testing.com
password: redhat



Now virtual domain testing.com is configured in the domain and users vasanth and hemanth are added.
