adjust that template, as this will likely be marked as spam by mail providers. Single sentence and a link to something isn't the most credible thing to send

https://www.mail-tester.com/ is handy for manual verification on a production system.

My recommendation is to make the email something along the lines of:

Hello there/<username>,

Please click on the link below to verify your email.
<link>

If you don't recognise this activity, please delete this mail.

Cheers,
Hostea team

Don't make it overcomplicated, but still all the useful information.

Btw, you might want to consider adding a DMARC policy and MTA-STS policy to the mail server to be more "trusted".

Also running my quick checks noticed that the AS that hostea is using is listed at some blacklist provider, https://www.uceprotect.net/en/rblcheck.php. It's not a known blacklister so I don't think it will cause any problems but just a FYI.

The IP from which mails are sent did not have a good reputation and was blacklisted in https://check.spamhaus.org/not_listed/?searchterm=51.91.145.50 because it belongs to an IP range that's globally problematic. But I sent a request that was granted to make it better a few months back.

Improvements to how the SMTP server is configured belongs to Enough and I copied your suggestion there so it is not forgotten. Should sending mail prove problematic, that will be very useful.
