Postfix smtp SASL authentication failure

Basic Pleskian
Hello,

i have a new Plesk 11.0.9. #34 server with Centos 6.3 64bit.
I made a few changes in order to be PCI Compliant.
I created a domain and try to send email with no luck.

As you can see from the logs, the pop/imap connection is successfull.
I login to webmail with the username/password successfully.

I can't send from Outlook/thunderbird etc.
Tried to rebuild emails with /usr/local/psa/admin/sbin/mchk --with-spam but no luck.
Any ideas?

Thank you.

Zero.

Backup the file </usr/lib64/sasl2/smtpd.conf>, and replace there a string <mech_list: DIGEST-MD5 CRAM-MD5 PLAIN LOGIN> to <mech_list: CRAM-MD5 PLAIN LOGIN>.

After that mail could be sent successfully without any authenticating requests.
 
Igor, thank you for your reply, but i still have a problem.
Now, the Outlook says: "None of the authentication methods supported by this client are supported by your server".
This happens only on sending mails (port 587).
Is there any way to fix the authentication failure with the DIGEST-MD5?
How else can i fix this (without losing the pci-compliance)?

Thank you.

Zero.
 
Strange, this issue has been fixed long time ago since 10.3.1 version with one of microupdate.
Are you sure that all packages are completely upgraded on your Plesk, especially authpsa?

Could you please confirm that all works fine if you use 25 port instead of 587 for SMTP connection?
 
Hello,

i was just checking my maillog when I saw this:

warning: SASL authentication failure: realm changed: authentication aborted

etc. like above.

yet, none of my customers has called about mail problems...

could you tell me a little more about this error, what it is and how to fix it?


thx.
 
Hi there,

I've suddenly started having the same issue following a restart of parallels outbound antispam.

Plesk 11 (all up to date), Centos 5.

I have a lovely helpful person from Parallels support looking at it because I'm baffled. Will update here if we find a solution.

Unless anyone else found anything?

Many thanks. That solved a similar issue I had with Eventum (Error: authentication failed: another step is needed in authentication).
 
Hi,
I've got a recently installed Linux Plesk 12 on CentOS 6 (centos6-plesk12_64).

I've got the exactly same problem as ZeroBorg (warning: SASL authentication failure: realm changed: authentication aborted... warning: somewhere[X.X.X.X]: SASL DIGEST-MD5 authentication failed: authentication failure.)
I've also tried IgorG suggestion (mech_list: CRAM-MD5 PLAIN LOGIN) and as ZeroBorg, Outlook then retruns: "None of the authentication methods supported by this client are supported by your server".
I don't know what else to do. I've searched foruns after foruns, i've tried a lot of suggestions but none solved my problem.

BTW, I don't know if that's relevant but my dedicated server is hosted by OVH.com)

Any help will be appreciate!
Thank you!
 
Hi Zeroborg!
Did you solved your problem? How? I've got the same problem as you :( !!
Thank you!

Hi team, I face the same problem as Joaquim_Ponte with a cloud VPS hosted at OVH.COM as well. Did someone either from Paralles or OVH can review and give a solution?

Sorry For the old thread revival. I have exactly the same set-up as you Centos 6.6, Plesk 12.0.18 hosted at OVH and of course the same trouble with the smtp authentication. Anyone found a resolution ? I already tried the ones mentioned in this thread with no success

Thank's !

Edit /etc/postfix/main.cf/

Look for:
smtpd_tls_auth_only = yes
and change it to:
smtpd_tls_auth_only = no

Save the file and run
postfix reload
