emails come from lazarusforumadmin@freepascal.org

freepascal.org is blacklisted on 2,

https://mxtoolbox.com/SuperTool.aspx?action=blacklist%3afreepascal.org&run=toolpage

Just after a quick look see, i would check/verify your spf settings, check/add your dmarc record.

another good site to get info from is https://dnschecker.org.
I have a do not mark as spam Gmail filter that includes lazarusforumadmin@freepascal.org, so it must be filtered at a higher level then.

I tried to make sense of the mxtoolbox's functionality, freepascal.org seems to be blacklisted by 2 sites, but digging further appears to be a money making scheme to whitelist a specific IP.  It isn't clear to me how to check if freepascal.org is on Google's blacklist.

hi

it would appears as the dns record for freepascal.org is missing the ~all setting for the spf record,
no dmarc txt record is present, having both this along with dkim, should allow for a better mail delivery.
Some mail servers will totally ignore mail coming from servers that do not advertise these value in their dns record, so you will not even see messages, they get dropped.

Also 'Reverse DNS does not match SMTP Banner.' could also cause issues with some mail servers, as the mail server is not advertising its ip address.

The blacklisting should auto resolve themselves when everything is corrected, however some of these black listers use a blanket ban on ip ranges, which if your unlucky your ip is next to a hacker/spam ip it could get caught in the net.... Do not be tempted to pay to remove, as their is no guarantee your server ip wont get banned again, and you just feed the monster.

Even though these are listed, most servers are configured not to use the blanket ban blackmail listers..

Just my personal opinion..


The best way to get accurate information on the forum is to post something wrong and wait for corrections.

Thanks for the explanation Josh.  I guess that means the mail.freepascal.org admin may have to update those records.

As a result of this discussion, I've changed the admin mail address to be an address of the sending domain.
So lazarusforumadmin@freepascal changed to forumadmin@lazarus-ide with corresponding spf and dkim entries.

Hello.

Now, with my hotmail.com address it does not work anymore (it was working 2 days ago).

If Hotmail is rejecting emails, they have detected unwanted activity from your server. While there are many reasons that Hotmail may block your email, the most common reasons are:

    Your email volume changed significantly or quickly.
    You are sending emails from a new IP address.
    You are sending email to unknown users.
    There is spam originating from your server
    Your Email Authentication fails
    Your DNS is incorrect.

As the mail server ip number and dns entries have changed, it may take a while for it to propagate around the dns servers. So its possible to get odd behaviour for a while, also the email volume coming out from new server has probably increased noticeably which can cause delivery issues.

Its best if possible to wait a day or two to let things settle... Obviously report any issues here, after that period Marc would be a better position to tweek any dns records, mail policies etc at that point... to help eleviate any issues.

The above is how I would suggest this important subject is addressed...
