Hi forum,
Can somebody help me to solve this problem. I have installed OM 2.2 and it
runs well except when somebody register directly by frontend. The email is
never delevered.
First I think it was due to the absence of Postfix and I install postfix.
After installing Postfix when I send email directly via command line no
problem
I come back and accomplish again the process via frontend but never deliver.

My installation
Ubuntu 12.04.3 LTS - 64 bits
OM 2.2
Postfix

My configuration
smtp_server : mail.mydomain.tld
smtp_port : 25
system_email_addr: conference@mydomain.tld
email_username: conference@mydomain.tld
email_userpass : mypassword
mail.smtp.starttls.enable: 1

I have a zimbra 8.0.6 server as MTA.

Thanks more for your reply
