mail notification problems
Submitted by deneb on Fri, 03/07/2008 - 10:35.
I have installed projectpier in www.netsons.org.
The installation was successful, but the notifications by e-mail do not work.
If I try the method with PHP tells me "mail sent" but the mail don't arrive.
If I try with SMTP tells me: "Notifier has failed to construct object mailer"

same problem... tried different smtp servers but i couldn't find a solution. :(
Error in the apache log:
File does not exist: /var/www/html/projectpier/public/assets/themes/default/stylesheets/http:, referer: http://linux2/projectpier/index.php?c=administration&a=tool_test_email
I'm having the same issue. SMTP doesn't work and php says it goes through on the test, but nothing arrives. I have activ collab installed on another account on the same server and it works properly, but this doesn't. I applied the "recepients" spelling patch and there are no errors in the log.
As far as I remember nothing mail related has been changed since AC was forked.
Make sure that the settings are correct, and if they are and it still doesn't work, then goto http://www.projectpier.org/live-support and see if there's anyone there who can help.
There is usually one person who is able to help at any one time.
I had the same problem: When setting Mail transport to 'SMTP server', I got the message 'Notifier has failed to construct mailer object', and when changed Mail transport to 'Default PHP settings', I got the message 'Test mail has been successfuly send', but no message was actually going out.
The solution was to leave Mail transport as 'Default PHP settings' and edit the file /etc/nullmailer/remotes this way:
my.inbox.com smtp --port=465 --user=myuser@inbox.com --pass=mypaswd
BTW, I'm running Ubuntu.
The hint was to see these error messages in /var/log/mail.log:
... nullmailer[4260]: Starting delivery, 2 message(s) in queue.
... nullmailer[4260]: Starting delivery: protocol: smtp host: my.inbox.com file: 1217413365.4855
... nullmailer[5739]: smtp: Failed: 550 Relay denied. Server requires authetication.
... nullmailer[4260]: Sending failed: Permanent error in sending the message
Then I investigate nullmailer and found the explanation here:
