Hi, I have followed Falko's tutorial below: http://www.howtoforge.com/virtual-u...urier-mysql-and-squirrelmail-fedora-14-x86_64 Somehow I am missing something as my postfix is unable to send e-mails. I went through the howto many times but I am unable to find what is causing the problem. When I try to send an email from terminal I am getting the below error: 451 4.3.0 <[email protected]>: Temporary lookup failure where example is just replace by the real e-mail address I am testing with. From logs i managed to find also some errors: Feb 10 19:26:28 example postfix/smtpd[10798]: connect from example.homelinux.com[127.0.0.1] Feb 10 19:27:05 example postfix/smtpd[10798]: warning: connect to mysql server 127.0.0.1: Access denied for user 'postfix'@'localhost' (using password: YES) Feb 10 19:27:05 example postfix/smtpd[10798]: NOQUEUE: reject: RCPT from example.homelinux.com[127.0.0.1]: 451 4.3.0 <[email protected]>: Temporary lookup failure; from=<root@localhost> to=<[email protected]> proto=ESMTP helo=<localhost> Feb 10 19:27:15 example postfix/cleanup[10806]: warning: connect to mysql server 127.0.0.1: Access denied for user 'postfix'@'localhost' (using password: YES) Feb 10 19:27:15 example postfix/cleanup[10806]: warning: 1D86D9AC7AE: virtual_alias_maps map lookup problem for [email protected] Feb 10 19:27:15 example postfix/smtpd[10798]: disconnect from example.homelinux.com[127.0.0.1] Feb 10 19:30:12 example clamd[1332]: SelfCheck: Database status OK. I removed my real domain name with the name example.... I really would appreciate any suggestions! Thanks everyone for looking! regards, sammd006
Please make sure you have the correct MySQL details in your /etc/postfix/mysql*.cf files. Also make sure that your network connection is working and that you have valid nameservers in /etc/resolv.conf.
Hi Falko, For /etc/postfix/mysql*.cf: Username / password are the same of the user i created for my mail DB. Below is what I have in my => /etc/resolv.conf : search homelinux.com nameserver 192.168.2.1 <= my private ip default gateway Is something missing? regards, sammd006
Can you try Code: nameserver 8.8.8.8 as the first nameserver in /etc/resolv.conf and see if that changes anything?
Hi Falko, I did the change as you have sugested but still I am having the Temporary lookup failure in my logs. regards, sammd006
There seems to be something wrong with your MySQL settings. Can you take the user and password from the mysql*.cf files and log into MySQL on the shell? Code: mysql -u [I]username[/I] -p
Hi Falko, I do not think although from log files there seems to be some warnings which are not clear to me too. I tried from terminal as you suggested and managed to log into the DB with username and password from my mysql*.cf files. I am missing something somewhere ... May I ask if I can send you my mail.cf conf file pm and you take a look maybe I have some missing entries? Regards, sammd006

Hm, MySQL is running, so that's not the problem. Are you absolutely sure that you can log in using Code: mysql -u postfix -p on the shell?
Hi Falko, I am 100% sure I can log in into my postfix database. Both from shell and from my myphpadmin link. Although from logs I can't understand why I am having errors stating that postfix@localhost is trying to connect with my db since I do not have postfix as a username but is named with different username as per below: Feb 17 23:34:21 example postfix/cleanup[32081]: warning: connect to mysql server 127.0.0.1: Access denied for user 'postfix'@'localhost' (using password: YES) Regards, sammd006
Do you have the username postfix somewhere in your configuration files in the /etc/postfix/ directory?
Hi Falko, No I do not have any username named postfix. My username is named different from my /etc/postfix configuration files. From logs, I cannot seem to find any authentication trials with my db from my configured user. regards, sammd006
