*Koha Setup:* 3.20 with UNIMARC from packages *OS:* Ubuntu Server 14.04 LTS I have setup Postfix with my mail settings. I successfully sent an email from the command line using the "mail" command. Using the "crontab.example" in "/usr/share/koha/bin/cronjobs/", I have edited my crontab and included the parts for: OVERDUE NOTICES ADVANCE NOTICES SEND EMAILS I have replaced the "__KOHA_USER__" with the appropriate user name, in my case "library-koha" and made sure to provide the correct path for KOHA_CONF. In Koha i have enabled the "EnhancedMessagingPreferences" option and for the patron I'm testing I have selected: Item checkout Item checkin Advance notice(0)- /I don't know if I should use this or not/ In the "Notices & Slips" menu I have the "CHECKOUT" and "CHECKIN" notices in "All Libraries", I haven't copied it to the branch I use. In the patron profile, under "Notices", I can see that the corresponding notice has been generated and the status is set to "sent". The problem is that I get no email to my email accout. When I check the "mail.log" in "/var/log/", I see that I get a 'status=bounced" and "<root@localhost>: Sender address rejected: Domain not found". As I said before I've tested postfix using the mail command from the terminal and I can send an email without a problem so I don't think it's a problem with the setup of Postfix (of course I could be wrong ) Anyone that has setup email notification working that can help me out or point me to the right direction? -- View this message in context: http://koha.1045719.n5.nabble.com/Problem-sending-email-notifications-tp5856...
