Email Not Sending

[beingnickb]

HI there,

We use both cPanel email and Microsoft 365 and our set up follows what is outlined in this thread. It was working great for a couple years and suddenly now we cannot send email from any cPanel mailboxes. We've tried sending from Outlook, Apple Mail on iPhones, and from Webmail. We do not get any errors, bounces, etc. The email appears to be sent, but simply never shows up in the recipient's inbox. Any ideas on how to trouble shoot? The domain is goodsocietybeer.com if that helps and we can still receive all email appropriately.

Cheers!

I can't say if this is your whole problem, but you have two SPF TXT records. You can only have one. You have to combine them together (with v=spf1 only once, at the beginning, and -all at the end, only once)

goodsocietybeer.com. 3582 IN TXT "v=spf1 a mx ptr include:secureserver.net ~all"
goodsocietybeer.com. 3582 IN TXT "v=spf1 include:spf.protection.outlook.com -all"

goodsocietybeer.com. IN TXT "v=spf1 a mx include:secureserver.net include:spf.protection.outlook.com -all"

Something like that. You can put ptr in there too but I'm not sure that helps any.

But you can only have one SPF record.

And you should make sure DKIM signing is active on that cPanel account, and that the proper DKIM key DNS record is in place on the authoritative nameservers for that domain.

In addition, if you are on WHM 108/110 and had custom PREROUTERS / TRANSPORTSTART you might have some broken SRS functionality and may need to add some information in your customization areas for SRS to work properly.

The first thing to check is the Exim log at /var/log/exim_mainlog to ensure the mail is properly leaving your server. If so, the advice from @mtindor is a good place to start.

I should've mentioned two other things:

1. I'm on a GoDaddy hosting plan - so I'm not sure how view the exim_mainlog or to understand if I'm on WHM 108/110. Are these things I need to be doing via SSH?
2. I have another domain on the account in which sending mail is working just fine.

Thanks for bearing with me, I know next to nothing about this stuff.

The Exim logs are something you would need to check on the command line. That log file is located at /var/log/exim_mainlog. If you're not comfortable with the command line, you may be able to get more details from the server from the WHM >> Mail Delivery Reports page through the interface.
