I provide "doveconf -n" in any case, maybe you can spot an issue?
I don't think, it's your config.
Setup a new server from scratch, without touching anything else on the new
system [no init.d scripts either], but copy Dovecot to it. And try that
system.
Some time ago my dovecot started to become BUGgy: Evertime I
restart the system, dovecot is started but I cannot login. I see
the following information in the logs:
Jul 4 04:04:36 mail dovecot: auth:
passwd-file(user,127.11.91.218,<nfkQjFT9vwCADFra>): no passwd
file: /etc/dovecot/imap.passwd Jul 4 04:04:36 mail dovecot:
auth: Error: BUG: Authentication client sent unknown handshake
command:
REQUEST?1183186945?20438?1?a8c7241e7b0778f9f0125da760cd16fa Jul
4 04:04:36 mail dovecot: imap: Error: Authentication server
didn't send valid SPID as expected: MECH#011PLAIN#011plaintext
Jul 4 04:04:36 mail dovecot: imap: Error: Disconnected from
auth server, aborting (client-pid=20438 client-id=1) Jul 4
04:04:36 mail dovecot: imap-login: Internal login failure
(pid=20438 id=1) (internal failure, 1 succesful auths):
user=<user>, method=PLAIN, rip=127.11.91.218, lip=73.82.101.172,
mpid=20439, TLS, session=<nfkQjFT9vwCADFra>
It does not help to restart the client. But when I then restart
the server service dovecot restart it works again.
You say, _each_ time you restart the system, this happens, but _never_ if
you start Dovecot manually?
I would first look into:
0) Dovecot v2.1 is pretty old. ;-)
a) Do you have more than one Dovecot version installed.
b) When and how often which Dovecot installation is started.
- -> e.g. is Dovecot started two times? I had some problem, when I started
Postgres two times in init.d, it worked most of the time, but sometimes
not.
c) Is Dovecot started too early?
- -> Maybe one dependency (LDAP, PAM, ...) blocks Dovecot, when someone is
logging in too early and Dovecot gets desync'ed.
d) Your init.d script throws an error, which you don't see on startup and
which does not happen, if you call the script manually.
- -> yes that can happen.
