I have follow your instruction on http://www.howtoforge.com/virtual_users_and_domains_with_postfix_debian_etch and it's works GREAT! However I got few questions 1. User still able to sending email without auth 2. When I tried to use option My outgoing smtp requires auth, I can't send email thank's before for your help
if you have: postconf -e 'smtpd_sasl_auth_enable = yes' postconf -e 'broken_sasl_auth_clients = yes' postconf -e 'smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_unauth_destination' in your postix config then you shouldn't be able to send mail without auth and enabling My outgoing smtp requires auth should work
Authentication is not needed if - you're sending emails to recipients on that server - you're logged in on that server (for example by using webmail) - are sending from an IP address listed in mynetworks in /etc/postfix/main.cf. What's in your mail log?
on main.cf, i only set mynetworks to 127.0.0.1/8 I'm sending using outlook If sending to onother email such as yahoo.com, mail.log shows me Relay access denied --> seems to be good But if I using same auth, can't send email.

Nothing else. What we got is only Code: Nov 3 09:28:06 mp-fs-13 postfix/smtpd[23876]: connect from unknown[my.ip.address] Nov 3 09:28:06 mp-fs-13 postfix/smtpd[23876]: lost connection after UNKNOWN from unknown[my.ip.address] Nov 3 09:28:06 mp-fs-13 postfix/smtpd[23876]: disconnect from unknown[my.ip.address]

Yes already for many times. Seems that the email program can't auth to the server. I tried to auth by telnet localhost 25 it's auth-ing succesfully
Not sure what it is, but I'd compare all configuration files with the ones from the tutorial again. Maybe there's a small typo somewhere.
also my postfix is being used for spam Note : I removed 127.0.0.1 from my networks. Because I don't use webmail at all here's what I found on logs Code: Nov 11 14:45:20 mp-fs-13 postfix/smtpd[17200]: lost connection after DATA from localhost[127.0.0.1] Nov 11 14:45:20 mp-fs-13 postfix/smtpd[17200]: disconnect from localhost[127.0.0.1] Nov 11 14:45:59 mp-fs-13 postfix/smtpd[17200]: connect from localhost[127.0.0.1] Nov 11 14:46:42 mp-fs-13 postfix/smtpd[17200]: NOQUEUE: reject: RCPT from localhost[127.0.0.1]: 554 5.7.1 <[email protected]>: Relay access denied; from=<[email protected]> to=<[email protected]> proto=SMTP helo=<127.0.0.1> Nov 11 14:46:48 mp-fs-13 postfix/smtpd[17200]: disconnect from localhost[127.0.0.1] Nov 11 14:47:12 mp-fs-13 postfix/smtpd[17260]: NOQUEUE: reject: RCPT from localhost[127.0.0.1]: 554 5.7.1 <[email protected]>: Relay access denied; from=<[email protected]> to=<[email protected]> proto=ESMTP helo=<gdiqbjvu> Nov 11 14:47:12 mp-fs-13 postfix/smtpd[17260]: NOQUEUE: reject: RCPT from localhost[127.0.0.1]: 554 5.7.1 <[email protected]>: Relay access denied; from=<[email protected]> to=<[email protected]> proto=ESMTP helo=<gdiqbjvu> Nov 11 14:47:12 mp-fs-13 postfix/smtpd[17260]: NOQUEUE: reject: RCPT from localhost[127.0.0.1]: 554 5.7.1 <[email protected]>: Relay access denied; from=<[email protected]> to=<[email protected]> proto=ESMTP helo=<gdiqbjvu> Nov 11 14:47:12 mp-fs-13 postfix/smtpd[17260]: NOQUEUE: reject: RCPT from localhost[127.0.0.1]: 554 5.7.1 <[email protected]>: Relay access denied; from=<[email protected]> to=<[email protected]> proto=ESMTP helo=<gdiqbjvu> Nov 11 14:47:12 mp-fs-13 postfix/smtpd[17260]: NOQUEUE: reject: RCPT from localhost[127.0.0.1]: 554 5.7.1 <[email protected]>: Relay access denied; from=<[email protected]> to=<[email protected]> proto=ESMTP helo=<gdiqbjvu> Nov 11 14:47:12 mp-fs-13 postfix/smtpd[17260]: NOQUEUE: reject: RCPT from localhost[127.0.0.1]: 554 5.7.1 <[email protected]>: Relay access denied; from=<[email protected]> to=<[email protected]> proto=ESMTP helo=<gdiqbjvu> Nov 11 14:47:12 mp-fs-13 postfix/smtpd[17260]: NOQUEUE: reject: RCPT from localhost[127.0.0.1]: 554 5.7.1 <[email protected]>: Relay access denied; from=<[email protected]> to=<[email protected]> proto=ESMTP helo=<gdiqbjvu> Nov 11 14:47:12 mp-fs-13 postfix/smtpd[17260]: NOQUEUE: reject: RCPT from localhost[127.0.0.1]: 554 5.7.1 <[email protected]>: Relay access denied; from=<[email protected]> to=<[email protected]> proto=ESMTP helo=<gdiqbjvu> Nov 11 14:47:12 mp-fs-13 postfix/smtpd[17260]: NOQUEUE: reject: RCPT from localhost[127.0.0.1]: 554 5.7.1 <[email protected]>: Relay access denied; from=<[email protected]> to=<[email protected]> proto=ESMTP helo=<gdiqbjvu> Nov 11 14:47:18 mp-fs-13 postfix/smtpd[17260]: lost connection after DATA from localhost[127.0.0.1] Nov 11 14:47:18 mp-fs-13 postfix/smtpd[17260]: disconnect from localhost[127.0.0.1] It seems there's a hole inside the server? So that the user can send email from localhost?
It says Relay access denied which means spammers tried to abuse your server, but they did not succeed. Nothing to worry about here.
Yes I don't care about that.. It's because I removed 127.0.0.1 from mynetwork. So how about the authentication issue?
