Hello everyone. I've decided to write this post after a week of headbanging agains my room's wall trying to make my postfix work. I've followed basically each guide i've found around... but i have a big problem. My server is an Ubuntu 8.04, and i've istalled succesfully Postfix, Postfix-mysql, Courier, amavis-new and greylist. I've configurated succesfully posftix to use tables stored in my mysql server, succesfully created my 3 virtual domains and one user for each virtual domain. Then i've configured Courier to authenticate to mysql too and it's working (i'm able to connect my thunderbird client to my mail server via imap and download my mail). So it seems that the "receive" part of my server is working fine. The problem comes when i try to SEND mail using my server as smtp server. It won't authenticate me. No way. I've tried to configure SASL to use courier-authdaemond (i've though that if it's authenticating for receiving... it could function to send too...) but... here comes the problem. It won't authenticate me. If i try to "testsaslauthd" i get the following error in auth.log: May 24 19:19:22 r23513 saslauthd[28263]: DEBUG: auth_pam: pam_authenticate failed: User not known to the underlying authentication module May 24 19:19:22 r23513 saslauthd[28263]: do_auth : auth failure: [service=imap] [realm=] [mech=pam] [reason=PAM auth error] Obviously the "[email protected]" is not the real value that i have in the log :p Otherwhise when i try to send mail "normally" from my client.. on auth.log i see those: May 24 20:14:09 r23513 postfix/smtpd[30997]: sql_select option missing May 24 20:14:09 r23513 postfix/smtpd[30997]: auxpropfunc error no mechanism available May 24 20:14:10 r23513 postfix/smtpd[30997]: _sasl_plugin_load failed on sasl_auxprop_plug_init for plugin: sql May 24 20:14:13 r23513 postfix/smtpd[30997]: NTLM server step 1 May 24 20:14:13 r23513 postfix/smtpd[30997]: client flags: ffff8207 May 24 20:14:13 r23513 postfix/smtpd[30997]: NTLM server step 2 That sounds to me really strange because i didn't configure the smtpd.conf to use auxprop-mysql plugin. My smtpd.conf file (copied in both /etc/postfix/sasl and /usr/lib/sasl2) contains the following: saslauthd_path: /var/run/saslauthd pwcheck_method: authdaemond authdaemon_path: /var/run/courier/authdaemon/socket mech_list: plain login log_level: 5 It's a week that i'm googling trying to find out it's not working and i still don't have an answer :( I repeat: all the "receive" part is working, amavis-new and greylist are working too.... only the smtp authentication is giving me this problem. Hope that someone can help me. Thanx in advance Ps: sorry for my english :(
Hi Falko, to configure the smtpd.conf i've used the directive contained in sasl's home page (i'll post the link later.. i'm at work up to now). For Postfix and Courier (with mysql) i've looked also (and compared settings with others) at the Virtual Users And Domains With Postfix, Courier, MySQL And SquirrelMail (Ubuntu 8.04 LTS) guide on this site. The problem is that i don't know how to debug saslauthd to see where it's giving problem... so if i'm missing something or doing something wrong...
As i told before, the reference site where i took sasl option is this: Options for Cyrus SASL And then How to set up a mail server on a GNU / Linux system And Integrating amavisd-new Into Postfix For Spam- And Virus-Scanning
The "Virtual Users And Domains With Postfix, Courier, MySQL And SquirrelMail (Ubuntu 8.04 LTS)" guide should be all you need - please don't mix it with other guides.
Hi Falko. I've checked again and again the part regarding the sasl configuration but it keep giving me the same error message that i've copied in the first post. Do you know if there is a way to debug saslauthd to understand where thos error is generated ?
Hi All. It's still NOT authenticathing but i've found a "curious" stuff. I've already told about the issue with testsaslauthd.. after a little testing i've seen that if i pass to the testsaslauthd the -f parameter (giving him the correct mux path the testsaslauthd SUCCESS ! Could that depend on some issues on chroot ?|?
