Why is SPF being validated against my mail server's IP instead of sender's IP?

http://serverfault.com – I have a mail server "example.com" which forwards all emails with recipient "me@example.com" to "me@gmail.com". My mail server runs Postfix and it uses the virtual_alias_maps mechanism to perform the forwarding. I also have SPF records installed for "example.com": v=spf1 a include:aspmx.googlemail.com ~all The problem is, whenever someone delivers mail to "me@example.com", Gmail validates the example.com SPF records against example.com's IP address! I thought it's supposed to validate against the original sender's IP address. For example, I'm on my laptop on my home Internet connection. I (HowTos)

I have configured my main.cf into postfix, It is sending mail into my gmail account, It is sending mail from abcd@gmail.com, Now I want that the mail should be sent from xyza@gmail.com or acb@mydomain.com, I am stucking with this problem for more than one hour, but I am not getting the solution for this, Please help me out.

Thanks in advance

Edit:

I have configured it, but at gmail server, send

I have an Ec2 instance on amazon AWS. i have installed , dovecot,postfix on server, mail incoming mail server is IMAP mail.xxxx.com .

I am able to configure my mails with gmail, outlook etc, using the IMAP. and can send and receive emails, The problem is that i want to send emails through PHP code using my mail server.

Have 3 servers - web server, mail server and outbound-only email server. The outbound-only email server sends transaction based emails on behalf of the web server (password reset, contact us, etc.)

How should I set up the DNS to improve email deliverability for the outbound-only email server.

i know its duplicate question

I tried using this code.

I have two gmail accounts, and I want to configure my local postfix server as a client which does SASL authentication with smtp.gmail.com:587 with credentials that depend on the sender address.

So, let's say that my gmail accounts are: acc1@gmail.com and acc2@gmail.com.

I have server A with an IP address only and a dummy FQDN (on the basis all machines should have a FQDN): pants.net.invalid. All mail is relayed through another server elsewhere, which works fine.

On server A, Postfix rewrites the sender address with smtp_generic_maps = hash:/etc/postfix/generic.

I have a virtual server with a static IP and a real FQDN. I set up Postfix on it and everything works.

I have setup Postfix as part of my ISPConfig implementation. It should just forward all mail. Clients should be able to define a new alias and receive mail on a different e-mail address, using ISPConfig.

I have a problem with receiving mails. I do not know if my server or the server of the sender is wrong configured.

I have a domain daniel-marschall.de which has following DNS RR:

daniel-marschall.de. 86400 IN CNAME viathinksoft.com.

The domain viathinksoft.com has the MX RR to "mail.viathinksoft.com":

viathinksoft.com.
