How to stop gmail from marking mail from my server as spam?
I had a spam problem about a month ago, which I fixed on my end. I notice now that email I send to recipients at gmail are automatically being marked as spam.
My mail server is Unix - Communigate Pro running on an old PowerMac. Outbound mail goes to my SMTP server, which is a Dell SonicWall ES-3300 I changed the IP address after the spam got past the SonicWall, and put the new address into my DNS, which is hosted by DYN.com
I looked at the header of a message I sent to my gmail account. I see something wrong with the SPF record
X-Mlf-Uniqueid: o201708020314430029673
Arc-Seal: i=1; a=rsa-sha256; t=1501643684; cv=none; d=google.com; s=arc-20160816; b=fxKfyh5i6PzjoNNZkIMPSigH
X-Received: by 10.55.197.88 with SMTP id p85mr27288566qki.281.15016
X-Mlf-Version: 8.3.2.6531
Return-Path: <prvs=138714c1e1=larry@com
Arc-Authentication-Results
X-Mailbutler-Tracking-Uuid
Mime-Version: 1.0 (Mac OS X Mail 10.3 \(3273\))
Authentication-Results: mx.google.com; spf=softfail (google.com: domain of transitioning prvs=138714c1e1=larry@comp
Yet when I check my domain with mxtoolbox, I see that the SPF is OK
What setting do I have that's causing this? Thanks.

The ~all could be problematic as well. This is interpreted as a "softfail", meaning some sort of testing is being done, and it is not a pass or a fail. Gmail might interpret this as suspicious, you really want a pass.

Adding the IP to the SPF record worked! The ~all is necessary for my backup email service, Intermedia. They have a lot of machines that the ~all applies to.
Thanks!
Thanks!

Modifying the SPF record with the IP address solved the problem! Thanks SO much for the recommendation of mail-tester.
The SPF record needs to cover whatever IP address you send email from that domain out through.
If it is 24.89.176.52, then the SPF has to cover that. Simplest fix would be to modify your SPF by adding IP4:24.89.176.52
