## Troubleshooting -- Can't send mail?
- Always check `journalctl -xe` to see the specific problem.
- Go to [this site](https://appmaildev.com/en/dkim) to text your TXT records.
If your DKIM, SPF or DMARC tests fail you probably copied in the TXT records
incorrectly.
- If everything looks good and you *can* send mail, but it still goes to Gmail
or another big provider's spam directory, your domain (especially if it's a
new one) might be on a public spam list. Check
[this site](https://mxtoolbox.com/blacklists.aspx) to see if it is. Don't
worry if you are: sometimes especially new domains are automatically assumed
to be spam temporaily. If you are blacklisted by one of these, look into it
and it will explain why and how to remove yourself.
