Verifying SPF etc.

[chrisjj]

Is there a checker service that will take an email from me and check it for SPF etc.? I do mean for an email, not for e.g. just the domain.

I ask apropos https://www.emaildiscussions.com/showthread.php?t=76295 and the fact https://spamchecker.mailreach.co/tes...e1c144dae54665 shows very poor deliverability to personal accounts of email through FM SMTP.

Yes my From address is in FM Settings -> My email addresses and the domain in FM Settings -> Domains.

Thanks.

Please look at this EMD thread from last year:
https://www.emaildiscussions.com/sho...d.php?p=630989

MXToolBox allows a free test of DMARC/DKIM/SPF and sender blacklists by sending a test email from the From address and sending server you wish to test to the ping? address shown in the first post in that thread. As my long reply in that thread describes, one of the DKIM signatures will fail to align.

I just tested this, and it still works just as shown in that thread.

• When I send using a FROM address at my personal domain (hosted at Fastmail), everything passes (with the warning that only one DKIM signature aligns, which is expected as described in that thread). I enable a reject DMARC policy for my domain.
• When I send using a FROM address at the fastmail.com domain, everything passes (with the warning that only one DKIM signature aligns, which is expected as described in that thread). Fastmail does not enable a DMARC policy, and so that creates another warning but no failure.

I've used https://dkimvalidator.com/ many times to check SPF+DKIM. Send it an email, wait, refresh the page, results appear.

I find https://www.mail-tester.com/ works well.

Bill, thanks and Well Done for that excellent explanation.

Same here.

Enable where? I see no such option in FM Settings -< Domains https://i.imgur.com/y4sf8wa.png albeit that I see see the considerate "Your domain is correctly set up to send and receive mail!".

Thanks. My empty test message got Pass on SPF and DKIM. The Spam Assassin analysis seems broken, with many : "The query to XXX was blocked due to usage of an open resolver. "

Thanks. My empty message got 9.4/10 and my one-line message got 10/10.

[chrisjj]

Despite the passes above, spamchecker.mailreach.co gives only 8.5/10, with all hotmail.com and most Outlook.com recipients judging the message as Spam - reasons undeclared.

This was on the one-line message that got 10/10 at mail-tester, but plus the required mailreach tracker code.

Hotmail/Outlook.com has notoriously bad spam filters. They are so bad you must check the spam folder every day or you will miss legit messages, even if nearly identical ones arrived yesterday. I have had my own messages sent from other email addresses end up in my Outlook spam folder. Doesn't matter if the sender is in your address book, you whitelist them, whatever. Has a mind of its own.

I just sent test emails from Fastmail (using FROM at both my personal FM-hosted domain address and a Fastmail domain address) to my Hotmail email address. Both messages were quickly received directly in my Hotmail Inbox. I don’t trust Hotmail either, but I have no current evidence that they are treating Fastmail messages as spam due to the outgoing server IP address or the domain name or email address.
