Hello, I have two identical CentOS 6.2 machines with stock Postfix package and unchanged config: # rpm -qa|grep post postfix-2.6.6-2.2.el6_1.x86_64 # postconf -n alias_database = hash:/etc/aliases alias_maps = hash:/etc/aliases command_directory = /usr/sbin config_directory = /etc/postfix daemon_directory = /usr/libexec/postfix data_directory = /var/lib/postfix debug_peer_level = 2 html_directory = no inet_interfaces = localhost inet_protocols = all mail_owner = postfix mailq_path = /usr/bin/mailq.postfix manpage_directory = /usr/share/man mydestination = $myhostname, localhost.$mydomain, localhost newaliases_path = /usr/bin/newaliases.postfix queue_directory = /var/spool/postfix readme_directory = /usr/share/doc/postfix-2.6.6/README_FILES sample_directory = /usr/share/doc/postfix-2.6.6/samples sendmail_path = /usr/sbin/sendmail.postfix setgid_group = postdrop unknown_local_recipient_reject_code = 550 On both machines I have appended afarber: Alexander.Farber at gmail.com root: Alexander.Farber at gmail.com to the /etc/aliases and run "newaliases". Both machines have several cronjobs and logwatch. One machine is a database server, I receive its cronjob mails just fine. The other machine (preferans.de) is running Drupal 7. I've configured it's MX records to point to Google Apps, so that I can receive mails addressed to that domain and this works well. Also I've set Drupal's From address to webmaster at prеferans.de and so sending mails by Drupal (for its user registration) works too. But sending mails to my Gmail address by cronjobs doesn't work. I suspect this happens, because Google is too clever and it thinks that mails coming from "preferans.de" shouldn't have the From header set to "afarber at static.169.40.9.176.clients.your-server.de" Jan 20 09:34:10 static sendmail[10577]: q0K8Y7mj010577: from=afarber, size=201, class=0, nrcpts=1, msgid=<201201200834.q0K8Y7mj010577 at static.169.40.9.176.clients.your-server.de>, relay=afarber at localhost Jan 20 09:34:10 static postfix/smtpd[10578]: connect from localhost.localdomain[127.0.0.1] Jan 20 09:34:10 static postfix/smtpd[10578]: 9B84B31EA0A1: client=localhost.localdomain[127.0.0.1] Jan 20 09:34:10 static postfix/cleanup[10581]: 9B84B31EA0A1: message-id=<201201200834.q0K8Y7mj010577 at static.169.40.9.176.clients.your-server.de> Jan 20 09:34:10 static sendmail[10577]: q0K8Y7mj010577: to=afarber, ctladdr=afarber (500/500), delay=00:00:03, xdelay=00:00:00, mailer=relay, pri=30201, relay=[127.0.0.1] [127.0.0.1], dsn=2.0.0, stat=Sent (Ok: queued as 9B84B31EA0A1) Jan 20 09:34:10 static postfix/qmgr[10025]: 9B84B31EA0A1: from=<afarber at static.169.40.9.176.clients.your-server.de>, size=823, nrcpt=1 (queue active) Jan 20 09:34:10 static postfix/smtp[10582]: connect to static.169.40.9.176.clients.your-server.de[176.9.40.169]:25: Connection refused Jan 20 09:34:10 static postfix/smtp[10582]: 9B84B31EA0A1: to=<afarber at static.169.40.9.176.clients.your-server.de>, relay=none, delay=0.14, delays=0.12/0.01/0.01/0, dsn=4.4.1, status=deferred (connect to static.169.40.9.176.clients.your-server.de[176.9.40.169]:25: Connection refused) So does anybody please have an advice on how to fix my cronjob mails?
