For example, if an email meets the conditions set in the first rule, it will be immediately moved to the Junk Email folder, then the following rules will not be applied on this email. If the first rule is a never block rule, when an email meets the conditions in this never block rule, it will remain in the Inbox folder even if it meets the conditions in the following block rules.
  • If you have checked the Stop processing other rules option for a rule, when an email meets the conditions of that rule, the rules after it will not be executed.

Hello,

I have downloaded and installed a trial version of Kutools for Outlook and would like your help with clarifying couple of issues.

I am running MS Outlook 2021 and from this app manage several accounts such as @live.com, @outlook.com, @yahoo.com and @gmail.com.

Question 1: If I block a domain by right-clicking on the junk message, would this domain be blocked for all accounts, e.g. @live.com, @outlook.com, @yahoo.com and @gmail.com or just the one the junk message was addressed to?

Question 2: I have accumulated a list of domains I would like to block. Is there a way to import this list into Kutolls rather than entering them one by one?

Thanks for your help. I am looking forward to minimize the junk with Kutools.

Regards,
Vladimir

Hi Vladimir,

The domain will be blocked for all accounts in your Outlook. Which one do you prefer? just the one the junk message was addresses to or for all accounts?
And Kutools does not allow importing a list of domains right now.
I have sent your suggestion back to the development department. Thank you for your comment.

What is the best way to block a SPAM IP address? I've tried putting in a valid IP address by adding a blocking filer to search for IP address in the Header.

Hi Keith,

Follow the second method in the post to maually create a block email rule with the specified ID addresses you want to block.
When open the following dialog box, check the header condition, click the specific words to add the IP addresses.

I tried doing that, but it keeps coming up with "Contain" not "Specific Words".

Hi Keith Howard,

Sorry for the inconvenience. After clicking the underlined text "specific words", a Text Contains window pops up, click the New button to open the Search Text window. In this window, type in the IP address you need, click the Add button (you can repeat this operation to enter multiple IP addresses as you need), then click the OK buttons to save the settings. See the following screenshot:
