I have installed Ubuntu Linux 10.04 with package postfix 2.8.5-2~build0.10.04.
I have configured postfix to send email through my ISP and this works fine: I can open mutt and send an email to an external address (e.g. google) and the email is delivered correctly.
The next thing I wanted to do was to define a mapping so that if I send a local email, it is delivered to my address which has the form:
my-username@my-isp-provider.net
In order to do this, I followed the postfix documentation and configured postfix as follows:
/etc/postfix/main.cf:
smtp_generic_maps = hash:/etc/postfix/generic
/etc/postfix/generic:
@my-hostname my-username@my-isp-provider.net
@localhost my-username@my-isp-provider.net
So, if I have understood the documentation correctly, this should cause all messages sent to any local user user-x with the addresses user-x@my-hostname and user-x@localhost to be delivered to my-username@my-isp-provider.net.
Instead, I observe the following unexpected behaviour:
- If I send email to
my-username@localhost, the message is delivered to my Linux box and not to my ISP accountmy-username@my-isp-provider.net. - Even more strangely, my ISP administrator has sent me an email, that they are receiving messages for destination
root@my-isp-provider.netwith subject 'Subject: Anacron job 'cron.daily' on my-hostname'. I suppose this is a local notification of my Linux box that is meant forroot, but how does this get mapped toroot@my-isp-provider.net?
At the moment I have checked all my configuration files and I have not clue as to how I can explain this behaviour:
- Why are my messages to address
my-username@localhostnot mapped tomy-username@my-isp-provider.netas specified in the configuration file? - Where do these messages for
root@my-isp-provider.netcome from, if the only mapping I have specifies the complete address of the receiver (my-username@my-isp-provider.net) explicitly? So if a message forroot@locahostgets mapped, it should be delivered tomy-username@my-isp-provider.netand not toroot@my-isp-provider.net.
