Hi

Can someone help me out to do email forwarding in postfix mail server.
Postfix is configured and working fine as i am able to send/receive mails from the same.

Thanks

Hi there,

Please elaborate a little on what you want to do. Are you trying to forward mail for a specific user to another address? All mail to a different server or domain?

Regards,

Clifford

Hi

For eg. i have configured mail server with a domain intelligence.com and hostname mail.intelligence.com.
Now i want whatever mails receive within this domain needs to be forwarded to my personal email id anurag2202@gmail.com.

So, what changes i needs to do to forward, received mails to my personal one....

Thanks

Hi cliffordw,
First of all you does not ellaborate what you want to achieve. If you want to receive all the incoming message to forward to single Email address. Then you have to configure catch all configuration .

First, set the following directives in /etc/postfix/main.cf:

virtual_alias_maps = regexp:/etc/postfix/virtual
virtual_alias_domains =

Second, edit /etc/postfix/virtual to send everything to your catchall address:

/.*/ catchall@gmail.com

Now rebuild the map file and restart postfix:

# postmap /etc/postfix/virtual
# /etc/rc.d/postfix restart

Test your setup by sending mail to some random address. It should arrive at your catch-all address. Watch /var/log/mail.log for success/errors.

$ echo "testing" | mail -s "test" john@example.com

First, set the following directives in /etc/postfix/main.cf:

virtual_alias_maps = regexp:/etc/postfix/virtual
virtual_alias_domains =

Second, edit /etc/postfix/virtual to send everything to your catchall address:

/.*/ catchall@gmail.com

Now rebuild the map file and restart postfix:

# postmap /etc/postfix/virtual
# /etc/rc.d/postfix restart

Test your setup by sending mail to some random address. It should arrive at your catch-all address. Watch /var/log/mail.log for success/errors.

$ echo "testing" | mail -s "test" mail@example.com

First, set the following directives in /etc/postfix/main.cf:

virtual_alias_maps = regexp:/etc/postfix/virtual
virtual_alias_domains =

Second, edit /etc/postfix/virtual to send everything to your catchall address:

/.*/ catchall@gmail.com

Now rebuild the map file and restart postfix:

# postmap /etc/postfix/virtual

$ echo "testing" | mail -s "test" mail@example.com

Well Sir u r correct, but by using catchall@gmail.com, all the emails sent to not existing email id's will also come to catchall directory or to the user whose id is in catchall but my concern is a bit different. I can elaborate a bit more...

I configured postfix mail server and working fine. I can send/receive using the same to/from any domain.
Suppose, there is a user created on postfix mail server anurag@intelligent.com. My concern is if i am sending mails to anurag@intelligent.com from my personal id anurag@gmail.com, then such mails should also forward to my other email id i.e. anurag2202@gmail.com.

Thanks

Hi again,

Am I correct in understanding that you want to do this for select email addresses only, and not globally for all users?

If so, you probably only need an alias (in /etc/aliases) or a ~/.forward file.

Regards

Hi
As cliffordw says you can achieve the thing using alias.It just forward the mail from one user to another .

# vi /etc/postfix/aliases
arunrag :arunrag@gmail.com

#sudo newaliases

# sudo postfix reload


check whether alias in your postfix configuration

# postconf -n|grep -i alias

Hi Cliffordw

As you suggested me to do an aliases thing. I configured postfix but aliases file does not exist in /etc/postfix.
I created it manually and did the same thing as you suggested me but the output is same i.e. mails are sending/receiving fine but not forwarded.

Please suggest.

Thanks
Anurag

The aliases usually exists by default, but its default location might differ depending on your distribution. For some distros it is in /etc/postfix/aliases, and for others in /etc/aliases. There may be other possibilities too. Check for the alias_maps setting in your /etc/postfix/main.cf file for the location.
