    I posted this on another thread...but the original poster of that thread is getting a different error message, so I'll try this one here...

    I used the postfix with virtual users and mysql tutorial...and I'm using Lenny

    This is the error I'm getting while trying to send using Outlook

    I am able to use webmail to send emails...and I am receiving SOME emails from other domains...but if I send an email from my work email address I get the email bounced back to me saying this

    There is NO ERROR in the mail log.

    Here is my smtpd.conf file

    My postfix


    telnet localhost 25
    ehlo localhost

    returns this...

    I do have "my server requires authentication" selected in Outlook...and I have no idea why the email from my work address gets bounced back.

    Any ideas?

    I wonder why there's nothing in the mail log. Are you absolutely sure that you connect to the correct server?

    The dns is set with Godaddy to my static IP address, so I don't know why I can't send from my work address to this server. The accounts on this server do get SOME email...but there's obviously a problem. I can't send using Outlook (webmail is fine) and some addresses can't send to this server too.

    The only time I see errors in the log, though, is when I try to send from Outlook.

    I have no idea what's wrong. Did you compare all your configuration files with the ones from the tutorial?

    I just re-checked all the Postfix parts of the howto, and everything looks OK. I'd think it was a DNS problem with my work email host...but I can't send using outlook either, so there's obviously a problem somewhere in the Postfix config.

    How would I go about removing all signs of Postfix, Courier, Amavis, etc. from the tutorial, so trying that part from scratch (without having to do a complete re-install)?

    I just re-checked (again) the files created in the tutorial and I had an extra space (whitespace) after my passwords...all seems to be working now as I can send using Outlook.

    I still can't send an email from my work address to my home server, but I have a trouble ticket in with that host to see what their mail log is showing.

    Thanks Falko!

    The receiving problem was a DNS problem. The DNS was set with the IP address in teh MX record. That's against policy, so some hosts (including my work ISP) rejected those emails.

    The extra space must have been the problem with the Outlook authentication, so now all is working. Thanks Falko for all you do!
