I've spent the last two days trying to resolve this problem and I am not even sure I fully understand it. Koha does not appear to be sending out email. I am using Koha 3.12 I am using Ubuntu 12.04 I am using Postfix port 25 I can send an email from commandline as such: mail -s "This is working" xxxxx.xxxxx.xxxxx CC: xxx.xxx.xxx This is working. Ctrl D I've checked logs: /var/log/mail.log, /var/log/mail-err.log. I've checked the koha logs. Nothing seems to show that there has been an attempt to send email from Koha. Postfix does show it it is running. I've check my processes and Postfix show up and is monitoring port 25. I am using a relay that we used on the old server and it works. I've checked crontab to make sure that the koha messing queue is working. I've checked the settings to make sure the Enhanced Messaging Preferences are turned on. Is there somewhere I need to go to turn on email in Koha? I did notice that each Patron Category has "none" under the messaging. I also notice that I can not turn on "item due" or "advanced notice" as they have a dash. Am I correct in assuming that this messaging category is by default on? Any clarification of how to determine if Koha is in fact setup to send email would be appreciated including steps to set it up. Thanks Phillip
