Send email via specific IP

[jariasca]

Hi all,

I have a server with 8 domains, 8 IP Addresses I have no problem getting emails for each domain.

I Need to send email via each domain IP example:
domain 1 = IP1
domain 2 = IP2
domain 3 = IP2
..etc...

Now all mail goes via my default IP "IP1"

please help
regards

I'm confused.

If you have 8 different domains, each with its own IP address, why can't you simply use each respective domain's FQDN to send outgoing mail?

Why are you wanting to use the IP addresses instead of the FQDNs?

Thanks, I don't know how to do it, by default the server send all mail via its default IP and I have a lots of problems with the DNS SPFs send the email to the Junk Folder.

please advise

The oslution for that is not to send emails under different IP addresses. A mailserver always sends the emails for all domains under its main IP. If you have problems with spamfilters, then check the following things:

1) Ensure that the reverse dns record for the IP address matches the hostname of the server.
2) Create spf records for all domain names and configure them to allow sending for the hostname of the server.

"v=spf1 ip4:216.25.xxx.xxx ptr:216.25.xxx.xxx a:abc.com mx:mail.abc.com ~all"

If this includes all servers that send mails for abc.com, then it's fine.
