RESOLVED: Postmaster problem with Ubuntu 8.04 Postfix Virtual Domains and users Hi all, I have recently (a couple of months ago) built a Postfix mail server on Ubuntu 8.04 using Falko's excellent howto. Everything has been working fine so far. I have an email address called newsletter that I use to send newsletters, which receives bounce messages and replies, another email address called unsubscribe, which receives unsubscribe requests. I have also recently added an email address called postmaster. I am enrolling in microsofts JMRP Program to help my chances of being able to send to hotmail accounts and also their SNDS program. I can log into the postmaster account using squirrelmail and the original Welcome message that I sent to it to create the directory is there. I can also send from it to any address I wish, inside or outside the domain. I can receive emails sent from addresses within the domain but I cannot, however, receive from addresses outside the domain. I have tried from several different external addresses and nothing shows up. When I initially ssh into my server and log into (username) the prompt often tels me "you have new mail". I type "mail to check it and delete it. during the initial setup I did do this part of the howto Code: 8 Modify /etc/aliases Now we should open /etc/aliases. Make sure that postmaster points to root and root to your own username or your email address, e.g. like this: vi /etc/aliases [...] postmaster: root root: firstname.lastname@example.org [...] or like this (if administrator is your own username): [...] postmaster: root root: administrator [...] Whenever you modify /etc/aliases, you must run newaliases afterwards and restart Postfix: /etc/init.d/postfix restart mine intitially looked like this: Code: [...] postmaster: root root: alan [...] I have tried to change it to this Code: [...] postmaster: root root: postmaster@myfqdn [...] but either way I still cannot receive emails into the postmaster account, or if I am, I dont know how to find them. I have been using squirrel mail, is there something that I need to know about the postmaster account? thank you in advance to any who can spare the time. Cheers Al.
