Fri, 10 Apr 2026 09:35:33 +0000 https://bugs.horde.org/ticket/7388 SMTP AUTH failure when accepting Kronolith invitation I have configured Horde to use SMTP AUTH for submitting messages through 'config/conf.php': $conf['mailer']['params']['port'] = 587; $conf['mailer']['params']['auth'] = true; $conf['mailer']['type'] = 'smtp'; This works just fine when writing new messages or sending replies: Sep 24 16:37:57 mail postfix/smtpd[19746]: connect from localhost[127.0.0.1] Sep 24 16:37:57 mail postfix/smtpd[19746]: setting up TLS connection from localhost[127.0.0.1] Sep 24 16:37:58 mail postfix/smtpd[19746]: Anonymous TLS connection established from localhost[127.0.0.1]: TLSv1 with cipher DHE-RSA-AES256 Sep 24 16:37:58 mail postfix/smtpd[19746]: 49B7A6041C: client=localhost[127.0.0.1], sasl_method=LOGIN, sasl_username=user@example.com Sep 24 16:37:58 mail postfix/smtpd[19746]: disconnect from localhost[127.0.0.1] The exception to this rule is, when I want to accept/deny an invitation that was send through Kronolith. After hitting the 'Go' button, the following error message appears: "authentication failure [SMTP: Invalid response code received from server (code: 535, response: 5.7.8 Error: authentication failed: generic failure)]." In the mailserver logs is logged at the same time: Sep 24 19:09:28 mail postfix/smtpd[21873]: connect from localhost[127.0.0.1] Sep 24 19:09:28 mail postfix/smtpd[21873]: setting up TLS connection from localhost[127.0.0.1] Sep 24 19:09:29 mail postfix/smtpd[21873]: Anonymous TLS connection established from localhost[127.0.0.1]: TLSv1 with cipher DHE-RSA-AES256 Sep 24 19:09:29 mail postfix/smtpd[21873]: warning: SASL authentication failure: All-whitespace username. Sep 24 19:09:29 mail postfix/smtpd[21873]: warning: localhost[127.0.0.1]: SASL LOGIN authentication failed: generic failure Sep 24 19:09:29 mail postfix/smtpd[21873]: disconnect from localhost[127.0.0.1] Accepting messages works just fine when I use the build in sendmail binary, but not when the replies go through SMTP AUTH. I would like to use SMTP AUTH, so that I don't have to duplicate the existing 'smtpd_sender_login_maps' that prevent From address spoofing.

Tue, 07 Oct 2008 12:36:51 +0000 https://bugs.horde.org/ticket/7388#t49432 This did not fix the issue for me as the current username and credential were not transferred with the parameters. imp/lib/Compose.php does add the current user and the password to the parameters before sending mail. The following patch fixed the issue for me: http://hg.pardus.de/cgi-bin/hg.cgi/horde/HORDE/file/0f8c1b39f7eb/imp/HK-GW-Auth_for_invitations.patch Mon, 17 Nov 2008 16:07:55 +0000 https://bugs.horde.org/ticket/7388#t50819 Changes have been made in CVS for this ticket: http://cvs.horde.org/diff.php/imp/docs/CHANGES?rt=horde&r1=1.699.2.373&r2=1.699.2.374&ty=u http://cvs.horde.org/diff.php/imp/lib/MIME/Viewer/itip.php?rt=horde&r1=1.37.2.43&r2=1.37.2.44&ty=u Wed, 07 Jan 2009 18:53:22 +0000 https://bugs.horde.org/ticket/7388#t51585 Added to Git and CVS.
