Is this the best way to get dovecot's pop3 process to run under xinetd? This
is what I did after I installed postfix and dovecot.
I am using Debian. I am using the dovecot local delivery agent.
---------first the dovecot configuration and version
information------------------
dovecot -n output:
# /etc/dovecot/dovecot.conf
log_timestamp: %Y-%m-%d %H:%M:%S
protocols: pop3 pop3s
disable_plaintext_auth: no
login_dir: /var/run/dovecot/login
login_executable: /usr/lib/dovecot/pop3-login
mail_extra_groups: mail
mail_location: maildir:/home/vmail/%d/%n
mail_executable: /usr/lib/dovecot/pop3
mail_plugin_dir: /usr/lib/dovecot/modules/pop3
pop3_uidl_format: %08Xu%08Xv
auth default:
mechanisms: plain login
passdb:
driver: sql
args: /etc/dovecot/dovecot-sql.conf
userdb:
driver: passwd
userdb:
driver: static
args: uid=5000 gid=5000 home=/home/vmail/%d/%n allow_all_users=yes
socket:
type: listen
client:
path: /var/spool/postfix/private/auth
mode: 432
user: postfix
group: postfix
master:
path: /var/run/dovecot/auth-master
mode: 384
user: vmail
grep -v '^ *\(#.*\)\?$' /etc/dovecot/dovecot-sql.conf output:
driver = mysql
connect = host=127.0.0.1 dbname=mailserver user=mailuser password=XXXXXX
default_pass_scheme = PLAIN-MD5
password_query = SELECT email as user, password FROM view_users WHERE
email='%u';
dovecot --version: 1.0.rc15
---------------------------------------
1. created a file dovecot-pop3 under /etc/xinetd.d with this content:
service pop3
{
disable = no
socket_type = stream
protocol = tcp
wait = no
server = /usr/lib/dovecot/pop3-login
user = root
}
2. Terminated the dovecot master process
#kill -TERM <pid of dovecot>
3. Restarted xinetd
#/etc/init.d/xinetd restart
4. telnet'ed to pop3 port. Because I am using the dovecot local delivery
agent, postfix needs the dovecot master process and its associated processes
already first running; otherwise, postfix will not be able to use the
dovecot local delivery agent.
#telent localhost pop3
Trying 127.0.0.1...
Connected to krueckeberg.org.
Escape character is '^]'.
+OK Dovecot ready.
quit
+OK Logging out
quit

I am using xinetd to start pop3-login because I have a VPS not a dedicated server and I am trying to conserve memory usage. Eventually, I will start also start imap-login via xinetd and will add those protocols (protocols = imap imaps pop3 pop3s).

That is a good point. Sounds like "login_processes_count=1" is the thing to do.
