I'm not sure this is what you want but I have an "or" condition:

    condition = ${if or{\
      {match{$mime_content_type}{(?i)executable}}\

{match{$mime_filename}{\N(?i)\.(exe|com|vbs|bat|pif|scr|hta|js|cmd|chm|cpl|jsp|reg|vbe|lnk|dll|sys|btm|dat|msi|prf|vb)$\N}}\ 

      }}
Here I use mime type and filename extension.

I don't think you can put hosts or sender_domains in like that:
${if or{{hosts = ...}{sender_domains = ...}}}


Ofcourse not, you need to add those checks you need too:

or{
     {COND1}
     {COND2}
}

where COND can be one with FORANY/FORALL:

forany{<a list>}{<a condition>}

   These conditions iterate over a list. The first argument is expanded
   to form the list. By default, the list separator is a colon, but it
   can be changed by the normal method (6.21
   
<https://www.exim.org/exim-html-current/doc/html/spec_html/ch-the_exim_runtime_configuration_file.html#SECTlistsepchange>).
   The second argument is interpreted as a condition that is to be
   applied to each item in the list in turn. During the interpretation
   of the condition, the current list item is placed in a variable
   called $item.

     *

       For forany, interpretation stops if the condition is true for
       any item, and the result of the whole condition is true. If the
       condition is false for all items in the list, the overall
       condition is false.

     *

       For forall, interpretation stops if the condition is false for
       any item, and the result of the whole condition is false. If the
       condition is true for all items in the list, the overall
       condition is true.

   Note that negation of forany means that the condition must be false
   for all items for the overall condition to succeed, and negation of
   forall means that the condition must be false for at least one item.
   In this example, the list separator is changed to a comma:

   ${if forany{<, $recipients}{match{$item}{^user3@}}{yes}{no}}

that way, you can parse those lists and combine the results in an OR . I 
think MATCH or EQ are the compareoperators you need.


Best regards,
