[gentoo-user] SMTP Authentication

[gentoo-user] SMTP Authentication

[Tito Valentin]

Hello list:

I have been trying to get SMTP authentication on Gentoo to work with no
success.  I am running qmail (netqmail package) with dovecot and saslauth.
 I am able to connect and read my mail through IMAP fine.  The problem is
that I cannot send email using my own SMTP server due to an authentication
issue.  Every time we try to send email out we get an error saying that it
cannot establish a connection because I am not part of the allowed rcphost
list.  I tried adding the remote host in the rcpthosts database but the
problem persists.  The only error I see in the log files for dovecot is
"Disconnected"

Can anyone point me in the right direction as to why I can't be
authenticated when sending email out?  Another thing is, it keeps
prompting me for my passwd.

Ha, I am having the same problem as Tito Valentin.  Is anyone out there
able to shed some light on this problem?  I opted for the use of
SquirrelMail in the mean time but it would be nice to be able to use
Thunderbird or Outlook.

Thanks,

Hello everyone:

Please add me to the list of folks who are unable to authenticate smtp.  I 
am also having this smtp authentication problem though I am using Courier 
(IMAP) and not dovecot.  It is driving me crazy.  What I have done in order 
to be able to send mail is to use my ISP's smtp server but I see how some 
folks wouldn't want their ISP's servers to be present in their email 
headers.

I hope someone is able to make a suggestion soon,
David

What does SMTP auth have to do with dovecot or courier imap?  What
authentication packages are you using?

I see one qmail - why qmail?   I have tremendous success with postfix,
and it's a little more modern, with less patches.

I don't know much about dovecot, but Courier is a kmore familiar
matter to me.  I used it until I figured out how to use Cyrus.  Cyrus
is a vast improvement over Courier, IMNSHO.  My buddy says that
dovecot is superior to both.  Whatever.

So, what is the underlying authentication datastore?

now, this seems very different.  Above is SMTP auth - yours seems to
be IMAP or POP auth problems. Which is it?  Is it just that you cannot
send mail?  or you can't get it either?

Are you using qmail as well?  If so, why qmail?  SASL is a bitch at
first, it always is.  It usually pays to return to the configuration
with a fine tooth comb, a fresh mind and lots of patience.  I ahve
configured many SASL based services, and I usually use Kerberos
(GSSAPI) as well, so it's non-trivial.

Please post a little more info about each of your specific
configurations, because there isn't enough info here to shake a stick
at.

Re: [gentoo-user] SMTP Authentication

I use stunnel to wrap imap and pop3. For SMTP I have TLS authentication 
using the saslauthd deamon and postfix. I have many virtual domains, but 
all accounts are local/plain unix accounts. Most do not have shell access.

I use the following use flags
mail-mta/postfix pam sasl ssl
dev-libs/cyrus-sasl berkdb crypt ntlm_unsupported_patch pam ssl

emerge --unmerge qmail
emerge postfix

in main.cf I have:
smtpd_sasl_auth_enable = yes
smtpd_sasl_security_options = noanonymous
broken_sasl_auth_clients = yes
smtpd_use_tls = yes
smtpd_tls_auth_only = yes
smtpd_tls_key_file = /etc/stunnel/stunnel.pem
smtpd_tls_cert_file = /etc/stunnel/stunnel.pem
smtpd_tls_CAfile = /etc/stunnel/stunnel.pem
smtpd_tls_received_header = yes
smtpd_tls_session_cache_timeout = 3600s
tls_random_source = dev:/dev/urandom

(I just use the same key from stunnel for TLS... I duno if it is even 
needed or not)

~ # cat /etc/sasl2/smtpd.conf
pwcheck_method: saslauthd
log_level: 3
mech_list: PLAIN LOGIN
authdaemond_path:/var/lib/sasl2/mux

~ # grep -v -- \# /etc/conf.d/saslauthd
SASLAUTHD_OPTS="${SASLAUTH_MECH} -a shadow -r"

If you guys have any problems with the above... I lurk on this list if 
you need help.
