I am facing an issue with the DKIM setup. We are sending newsletters which are going to spam in gmail. The dkim & spf passes. Even the reverse dns is setup properly. Below is a copy of mail headers that I see in gmail.

I Think so the Received: (from abc#localhost) is causing the issue.
What I need to know how to resolve it. Instead of localhost it should use mydomain.com This is my first time setting up such kind of server.
This may be the problem with the envelope sender and from address because,an email has two addresses associated with sending it: the envelope sender, and the From: address. The envelope sender is where computers should respond (in the case of bounce messages or errors); the From: address is where people should respond. In most cases, the envelope sender and the From: address match.Some case the Gmail put the mails which the 2 sender field did not match. You may try with the same.

According to this question Is it possible to retrieve the RFC 2822 (or any) headers from an email with the Outlook/Office 365 REST API?
by doing
GET https://outlook.office.com/api/beta/me/mailfolders/inbox/messages$select=InternetMessageHeaders
But I can get the header only for inbox items, I need to retrieve the header for the sent items as well!
You can get it using the $value parameter to get the MIME type of the message and read the entire header!
From Example 4 - Get message
GET https://graph.microsoft.com/v1.0/me/messages/4aade2547798441eab5188a7a2436bc1/$value
Response

The email headers are created by the email servers, these details can
include who sent the message, the software that was used to compose
it, and the email servers that it passed through on its way to the
recipient. Hence you are not able to view the header information for
the sent messages.

--===============7137656464834900843==--
Now, everything is setup and OK, the DKIM, SPF, and DMARC.
I'm trying to remove X-Spam-Last-External-IP: XXX.XX.X.XXX header that forwards client IP, and to somehow modify Received-SPF: Pass (sender SPF authorized) identity=mailfrom; client-ip=XXX.XX.X.XXX; helo=mail.example.com; envelope-from=diana#example.com; receiver=someid#mail-tester.com which also forwards client IP to every e-mail sent.
I've had no success in removing the first header or modifying the second one.
Also, the e-mail never get into an Hotmail mailbox, not even from RoundCube, and mail.log file shows a successful queued for delivery message. What am I doing wrong?
When connecting over SMTP most servers will add a Received: header with the relevant details. This is an important part of the email reputation ecosystem since it means sending IPs must be accountable for their sending activity.
If you make use of an email relay that may shift the address shown one step down the chain, or you can choose to use an API-driven email service where there's no direct SMTP connection between your application and the mail service. In those cases the IP shown is almost always the mail service you're using and not your own system, giving you a layer of separation and security.
My emails are delivered to spam folder at gmail and yahoo mail.
PTR, DKIM (1024 bit), SPF are okay. I don't know whether DMARC and ADSP or Domain Key are needed to be configured or else?
In addition, I have checked Bulk Senders Guidelines "support.google.com/ ----> mail/answer/81126" but I think I am in compliance with it, except the Format section of the webpage. I wonder is my email header is ISO-8859-1 compliant as is requested by gmail or my messages are formatted according to RFC 5322 as it is required!?
However, I have checked my email by various tools including:
1- www.brandonchecketts.com/emailtest.php
2- mail-tester.com (my email score: 10/10)
3- toolbox.googleapps.com ----> /apps/messageheader/analyzeheader
and all of them are ok and I can't get it right why my emails are categorised as spam?
By the way, I am not a bulk sender, my ip is clean (not in any of blacklists) and I have just started to configure my new VPS host.
I am confused a bit as it is obvious, Please guide me.
Note: (I have changed email addresses and real IPs in the message header)

Since you've said that you've modified the header records, it's hard to determine a few things. However, the sending mail server seems to be webmail.domain.com --- Are the DNS records set to point to mail.domain.com or webmail.domain.com or both?
Since you've done the rest of the configuration: just enter a dmarc DNS record, it might increase your server's reputation. Speaking of reputation, if your email server only handles a few emails a day from a couple of users - then your reputation as a 'spammy' server can be greatly affected by a just a few unopened or manually spam marked messages. Also, I believe there's a time lag between when you setup a mail server and when it's reputation gets out of the 'default to spam' folder.
registration email sent from a new website I am building end up in the receivers' spam folders, they are classified as spam. So far I have no idea why this happens. Therefore I am posting the email header of such a registration email. Please note that this email posted here has not been classified as spam, however all registration emails generated and sent are like this one.

Do you have a proper SPF record set up for your domain? Most domains should respect whatever address your mail is coming from as long as it is in your SPF record. Wikipedia has a pretty good write-up on how SPF works.
I moved one client to Google Apps and it's been crazy! So many problems! And I never had these kind of problems
Client is using Outlook with Imap to manage his Google Apps Gmail account
Now when he sends email he got this kind of errors (for some addresses only):
Delivery to the following recipient failed permanently:
spf-test#openspf.org
Technical details of permanent failure:
Google tried to deliver your message, but it was rejected by the recipient domain. We recommend contacting the other email provider for further information about the cause of this error. The error that the other server returned was: 550 550 5.7.1 <spf-test#openspf.org>: Recipient address rejected: SPF Tests: Mail-From Result="pass": Mail From="nelson#samarfil.com" HELO name="mail-qa0-f45.google.com" HELO Result="none" Remote IP="209.85.216.45" (state 13).

I've already configured DNS to TXT record v=spf1 include:_spf.google.com ~all
what else can I do to fix this?
It's normal to receive this message, as that SPF test uses the error message to send back results. Are you experiencing errors when sending to other addresses?
