Assigning sender's IP on V 10.4.4

[PROBUDHAN]

Hello

Our server is running on Plesk V 10.4.4 with CentOS 6

I would like to know how I can assign a specific IP for all our outbound emails instead of using the default virtual shared IP

I edited the senderip file and inserted the IP I want associated with the domain and the mail server but the emails are still originating from the shared IP

Kindly suggest me a way I could send the emails from another IP


Thanks

Changing QMail default IP

If you’ve got a Plesk server and some unsavoury character has hosted and spammed from your server, even if you remove them you may find your IP is blocked by many of the blacklists – even though this will only be temporary for 24 or 48 hours, this is still an issue for your remaining clients.

What you need to do it temporarily change the qmail sender IP address, this is very easy to do and as I say, it’s temporary, a server reboot gets everything back to normal.

Let’s say your qmail IP address is 1.1.1.1 and you want to change it to 2.2.2.2. Your gateway is 3.3.3.3 and does not change.

Run

/sbin/ip route

You see something like

1.2.3.4/1 dev eth0 proto kernel scope link src 1.1.1.1
1.2.3.4/16 dev eth0 scope link
default via 3.3.3.3 dev eth0

To change the default qmail IP from 1.1.1.1 to 2.2.2.2:

/sbin/ip route change default via 3.3.3.3 dev eth0 src 2.2.2.2

That’s all there is to it. All qmail outgoing mails now leave from IP 2.2.2.2 instead of 1.1.1.1

Hi abdi

Thank you so much for your reply

I ran the command you gave and it returned the following

xxx.xxx.0.0/16 dev venet0 scope link metric 1002
default dev venet0 scope link

Could you please guide on what to run next?

btw, I also tried using the IP I want the emails originating from in the bindroute and senderip files, but no help

Thanks again!

You can PM me the full response you get when you run

/sbin/ip route

Hi abdi

I can't see a PM link, can I email you instead?

Thanks

Hi Abdi

Have sent you an email

Kindly check at your convenience and advise

What OS are you running?

Ie your /sbin/ip route seems not to give complete IP information on your server ...
Is it a VPS or a dedicated server?

 

[PROBUDHAN]

It is a VPS with CentOS 6

Try these instructions to see if they can help incases of VPS

I followed the smtproutes method mentioned in one of the links above...still no luck

 

[abdi]

Looks like you have to change the main IP of the VPS to resolve that ...AM sorry I have not done this before on a VPS but googling leads to the same solution, eg

http://forum.lxcenter.org/index.php?t=msg&goto=37138&

Am so sorry I was unable to help resolve this problem ...

 

[PROBUDHAN]

Thank you so much abdi for taking the time out to look into it.

If this doesn't resolve, then I am afraid I'll have to change the VPS

 

[PROBUDHAN]

Just to update this thread

I was finally able to change the mailing IP through the sbin/ip route method

/sbin/ip route change default via o.l.d.i.p dev venet0 src n.e.w.i.p

Thanks

 

[abdi]

Interesting, am happy that it worked for you eventually..

 

[PROBUDHAN]

Yeah finally changed it, thanks

However mails to Gmail are still received with an old IPv6 address that I have removed from the server altogether. Even though its been like 8 hrs since I've removed it.

How long do you think it would take Google to receive the new IP. Yahoo is already receiving emails from the new IP

Do I just need to wait or is there something I need to do?

 

[abdi]

Hey, did google start recieving email from the new IP?
