FQN Outlook n Postfix Issue

[grungy]

I upgraded my server to newest trunk and mail sending works fine with thunderbird, but some of my clients use outlook and they have a problem with sending. I installed outlook and indeed there is a problem, I get the following message:

Code:

504 5.5.2 <GRUNGY>: Helo command rejected: need fully-qualified hostname

Well I took the main.cf postfix conf file from an older trunk, now sending works....

have you enabled the authentication in your client? the current main.cf looks good... Please post the smtpd_helo_restrictions section of your main.cf

[grungy]

trunk-20071125

Code:

smtpd_helo_required = yes

smtpd_helo_restrictions      = permit_mynetworks,
                               permit_sasl_authenticated,
                               reject_invalid_helo_hostname,
                            reject_non_fqdn_helo_hostname

Seems that Outlook and TB (and others) use different helo greeting hostnames - Outlook only the Windows machine name? And TB?

I think, if you comment theese two lines
reject_invalid_helo_hostname,
reject_non_fqdn_helo_hostname

then it should work, but this is not a long time solution...

hm, yes - you're right...
maybe the automated outlook mailsettings software did not do everything the right way... :-)

I am having the same problem:

Yesterday I reformated and installed debian and ispcp-omega-trunk-20071126.
I did all like in the German Tutorial, but when I try to send some mails via Outlook I get the same error.

Before reformating I used an older trunk version of ispcp, it was working fine.

Has anybody an solution?

please post a whole mail.info sequence of the transaction that failed...

I censored the e-mail addy's.

Hope that's all you need?
