postfix: virtual alias sends with server's domain

Jalalabee · 05-26-2013, 03:52 AM

postfix / centos 6.4 64-bit

server@server.com can send and receive mail.

virtual@virtual.com receives mail just dandy and correctly but when sending mail it shows the sender of virtual@server.com.

Where can I start?

This does it for me every time:

Code:

[root@mail ~]# vi /etc/postfix/virtual

# add at the head
cent@mail.virtual.host userB

[root@mail ~]# postmap /etc/postfix/virtual

[root@mail ~]# /etc/rc.d/init.d/postfix reload

(source: www.server-world.info/en/)

if you did do this step, could you add some configs, (obscure the names of course) would make it easier to look for a solution

I gave that a go, no dice.

One thing I'm very unsure about are these default values: mynetworks 168.100.189.0/28, 127.0.0.0/8

From Webmin panel:

main.cf

alias_maps hash:/etc/aliases

parameters defined as per defaults

alias_database hash:/etc/aliases

config_directory /etc/postfix
daemon_directory /usr/libexec/postfix

html_directory no
inet_interfaces all
mail_owner postfix
myorigin $myhostname
queue_directory /var/spool/postfix
setgid_group postdrop
unknown_local_recipient_reject_code 550

If there is anything more specific I can grab, I can do.

I did attach the html for the webmin log which includes the above plus a table at the bottom I couldn't reproduce fast enough/readable enough.

I can not tell you if this solves anything, but I have always added my virtual hosts to the "my destination" in main.cf (im doing this out of the top of my head, its been a long time since i setted Postfix up from scratch)

Code:

mydestination $myhostname, localhost.$mydomain, localhost, $mydomain, $myVirtualDomain

No dice.

I explicitly hardwired in the main.cf:

myhostname = virtual.com
mydomain = virtual.com
myorigin = virtual.com
mydestination = virtual.com, www.virtual.com
relay_domains = virtual.com

Still sends, still shows the server's hostname.

Back to basics, where would I assign 'user' to 'virtual.com' rather than 'server.com'?

Should I just wipe and try a tutorial? And if so, does this look good: http://www.howtoforge.com/virtual-us...tos-6.3-x86_64

As far as i used my virtual hosts to send from, i never ever had to assign them. All users just got a second email box.
Then i configure my email client and all works well.
The virtual users are to forward email from one virtual user to a real system users mailbox.

That tutorial looks good if you want to wipe. Personally if i need a tutorial i use the ones from http://www.server-world.info/en/ They offer one for most distributions and keep it simple to do and understand why.
