Email alias problem

[ThoughtMemory]

I have a problem with email aliases not working correctly.

On the disk there's a maildir folder for aliases, rather than them being pointed to the correct email user.

This is the the main.cf file:

# See /usr/share/postfix/main.cf.dist for a commented, more complete version


# Debian specific:  Specifying a file name will cause the first
# line of that file to be used as the name.  The Debian default
# is /etc/mailname.
#myorigin = /etc/mailname

smtpd_banner = $myhostname ESMTP $mail_name (Ubuntu)
biff = no

# appending .domain is the MUA's job.
append_dot_mydomain = no

# Uncomment the next line to generate "delayed mail" warnings
#delay_warning_time = 4h

# TLS parameters

and here's an excerpt from the mail logs if I send a test message to the email alias:

1) Are you sure that there is no mailbox for the email address of the alias in ISPConfig?
2) Is the part in front of the @ of the alias identical with a Linux system user in /etc/passwd?
3) Is the alias listed in /etc/aliases

Absolutely, there's several aliases setup, all showing the same behaviour

2) Is the part in front of the @ of the alias identical with a Linux system user in /etc/passwd?

No, there's only one Linux system user, other than default/system users.

3) Is the alias listed in /etc/aliases

No.


The mail_forwarding table in the ispconfig database also correctly shows the setup aliases.

the same problem here under ubuntu v10.04, postfix ok, mysql tables, sending mail ok, but using alias is not working at all !

a folder is created for the alias and maildrop put the mail in instead of forwarding it to the right email destination.

Any ISPConfig 3 issues ?

if anyone coud help it would make me very very happy

[ThoughtMemory]

I've done a workaround by removing the folders created for the aliases and soft linking them to the actual users, not ideal, but at least it works.

I'm in the process of checking whether the virtual machine used by Howtoforge for the Ubuntu/ISPConfig3 guide also has the problem, if so we'll know it's definitely an issue with the setup.

This happens because you commented out the line "content_filter" in main.cf. Remove the # in fron of this line and restart postfix.

The virtual machine does not have this problem as it is installed due to the perfects erver guide without manual changes in the main.cf file. The reason why you have this problem is because you commented out the content filter line which disables also the alias rewriting as rewriting is done sfter the content has been filtered.

ok, but I don't have any content_filter rules in the main.cf file created by ispconfig3 install… and in the master.cf it just says :

127.0.0.1:10025 inet n - - - - smtpd
        -o content_filter=
       …

i've putted "content_filter = amavis:[127.0.0.1]:10024" in main.cf is it ok ?
then amavis restart

it seems to work, but amavis said "file not found /etc/mailname"

anyway, thank you so much for the content_filter information !

[till]

ok, but I don't have any content_filter rules in the main.cf file created by ispconfig3 install…

Then ISPConfig 3 is not fiully installed or the main.cf file has been replaced after ispconfig was installed. Please run a ispconfig update by choosing the manual update method as described here and choose to reinstall sercices during update.

Ok, but what if you don't want to run amavis?

My mail is filtered via Google Postini's spam service, and this particular machine is low-specced, as it's only hosting a few domains for mail/plain web, I don't need or want to run amavis
