How to send mail to Gmail from the users I created in DigitalOcean and the mail accounts I created in ThunderBird?

I have a droplet and domain at DigitalOcean. I’ve added users and I’m logging into their mail accounts with ThunderBird. I can send and receive mail between these users, but I can’t get mail from these mail accounts to Gmail and vice versa. No error. Also, when I checked the BlackList status, I saw that my droplet-IP address is in the BlackList: RATS Spam, SORBS SPAM, UCEPROTECTL3. How can I solve the problem?

Hello Rozerin,

Indeed, the fact that your droplet’s IP address is listed on blacklists like RATS Spam, SORBS SPAM, and UCEPROTECTL3 is likely causing your emails to be blocked or marked as spam. You should request removal from these lists. Each blacklist has its own process for this, so you’ll need to go to their websites and follow the steps they provide for removal:

Also, considering using an SMTP service could make things easier for you. These services, such as SendGrid or Mailgun, are designed to handle email delivery and can help avoid issues like being placed on blacklists. They take care of the technical aspects of email delivery, which could be a big help in ensuring your emails are successfully sent and received.

Additionally, you might want to read this article from DigitalOcean: Why You May Not Want to Run Your Own Mail Server. It explains the challenges of managing your own mail server and could provide you with valuable insights into whether this is the right approach for you.

Managing a mail server can be complex, especially when it comes to ensuring reliable email delivery. Whether you decide to work through the blacklist issues or switch to using an SMTP service, the goal is to make sure your emails reach their intended recipients.

If you have any more questions or need further help, feel free to ask.

Heya, @rozerinyildiz

Having the IP address listed in RATS Spam, SORBS SPAM, UCEPROTECTL3. will likely cause issue with the outgoing mail deliverability (mostly due to SORBS). You can always request a delist and this should fix the issue in few hours, but there is a high possibility that the issue will occur again and this can be not your fault.

As Bobby mentioned, please check our article on why you may not want to run your own mail server:

I’ll recommend you to use an explicit email provider like SendGrid or any other dedicated email provider. This will ensure your emails will be delivered successfully.

In the meantime you can request a delist from SORBS:

You’ll need to create an account and then request the delist. The other lists you’ve mentioned usually scan against SORBS database and use their data as reference. If the IP gets delisted from SORBS you should be good with the rest of the blacklists as well.

Hope that this helps!
