cannot send mail in outlook

Weird problem. I Have spend a lot of time searching answers in this site, But no one seems to work.
Ispconfig is working fine, webmail is working fine, but when I try to send mail via outlook, it cames back with error

554 <[email protected].>: Relay access denied

If I try to send mail someone in same domain, it works fine!

This one looks weird in /var/log/maillog


Jul 4 11:24:47 www postfix/smtpd[15250]: NOQUEUE: reject: RCPT from wireless-pvi.oulunkaari.net[213.255.164.46]: 554 <[email protected]>: Relay access denied; from=<[email protected]> to=<[email protected]> proto=ESMTP helo=<MYWINDOWSCOMPUTERNAME>

 

You must enable "Server requires authentication." in your email client.

 

Hi!

I have done that, and try to make different combinations how to authenticate user, but still get same error message. Funny thing is, that if I mail for my self or someone under in same domain, everything is workin fine!

Im totally lost...

 

Have a look at this post: http://www.howtoforge.com/forums/showpost.php?p=3728&postcount=4

Did you configure Outlook like this? http://mail.cs.uiuc.edu/relay/outlook-config.html

 

Well, outlook settings are fine, and ehlo for localhost gives lines like this:

250-www.mydomain.com
250-PIPELINING
250-SIZE 10240000
250-VRFY
250-ETRN
250-STARTTLS
250-AUTH PLAIN LOGIN
250-AUTH=PLAIN LOGIN
250 8BITMIME

 

Yep, that username is typed like web(id)_user. There is a test settings button in outlook, and pressing that button gives message that everything is working fine! It is working fine, if I send mail someone in same domain, but no outside!

 

maakka, FYI. this is normal operation that you can email yourself but no one outside. by default the mail server only allows receiving of emails to domains it hosts but not others outside it's domains unless you are allowed either by being part of it's local network (postfix's mynetworks= setting) or authenticated to relay mail.

Just because you send from a domain that is hosted by that server doesn't nessessarily mean you are allowed to send as this is a method spammers used to use in the past to send mail anywhere.

 

That smtp setting are checked, and after trying different combinations I just cant send mail.
Of course, when using webmail everything is working fine!!

 

Is "Server requires authentication." enabled as described here? http://mail.cs.uiuc.edu/relay/outlook-config.html

What's in your mail log when you try to send a mail with Outlook?

 

I have the same problem from today. I believe the problem is in ISP. ISP blocks SMTP.
The problem started today. Yesterday was everything fine and today one user told me that he can not send emails. There wasn't any change from me on ISPConfig or on the server.
I just don't know yet how to test it.

 

Please check your mail log, and send some test mails. Also ask your ISP if it is true that they started blocking port 25. If so, have a look here: http://www.howtoforge.com/forums/showthread.php?t=72&highlight=relayhost

 

Here is some logfile:

Jul 12 11:11:33 www postfix/smtpd[21192]: NOQUEUE: reject: RCPT from unknown[10.26.100.90]: 554 <[email protected]>: Relay access denied; from=<[email protected]> to=<[email protected]> proto=ESMTP helo=<!!MYWINDOWSCOMPUTERNAME!!>
Jul 12 11:11:35 www postfix/smtpd[21192]: disconnect from unknown[10.26.100.90]

Im using outlook 2003, also tested with mozilla thunderbird.

 

What's in /etc/postfix/main.cf (please strip out the comments)?

 

Sorry for asking, but shouldn't the [email protected] be rewritten to any web_x usr from the virtual table or are installations of ISPConfig wihout virtual maps possible?

Please run

Code:

postconf -e 'smtpd_recipient_restrictions = permit_sasl_authenticated,permit_mynetworks,reject_unauth_destination'

and restart Postfix.

 

Postfix with SASL should allow relaying if a user authenticates against a user database or lookup table. I'm not sure this is setup either in the perfect setup or in ISPConfig. That's something Falko or Till should let us know.

If I use the FQDN as my smtp server (that's the machine's FQDN - not the virtual host) is smtp set up to authenticate users and relay mail?

If so, how does a user such as web1_name send mail through ISPConifg?

Or is the smtp server of the ISP one uses such as AT&T needed to handle all smtp traffic?

 

That's what it says in main.cf

I have that in my main.cf file but it still doesn't work
