<p dir="auto">Thanks for considering it!</p>

<p dir="auto">I'm thinking it might be a performance issue to call a script for every image (there can be a lot of them in a single email).</p>

<p dir="auto">I was thinking you’d invoke the script once for each email, at display time. Does that change things for you? The process on your side would look something like:</p>
<pre style="background-color:#F7F7F7; border-radius:5px 5px 5px 5px; margin-left:15px; margin-right:15px; max-width:90vw; overflow-x:auto; padding:5px" bgcolor="#F7F7F7"><code style="background-color:#F7F7F7; border-radius:3px; margin:0; padding:0" bgcolor="#F7F7F7">on display_html_email:
proc = run(uri_approver)
for image in remote_images:
proc.write(image)
result = proc.read()
if result is 'allow':
display(image)
proc.end()
</code></pre>

<p dir="auto">It might be nice with a more flexible solution, but if all you want is a regular expression to allow certain images then I already implemented <code style="background-color:#F7F7F7; border-radius:3px; margin:0; padding:0 0.4em" bgcolor="#F7F7F7">MmAllowedImageURLRegexp</code>. For example:</p>
<pre style="background-color:#F7F7F7; border-radius:5px 5px 5px 5px; margin-left:15px; margin-right:15px; max-width:90vw; overflow-x:auto; padding:5px" bgcolor="#F7F7F7"><code style="background-color:#F7F7F7; border-radius:3px; margin:0; padding:0" bgcolor="#F7F7F7">defaults write com.freron.MailMate MmAllowedImageURLRegexp -string "https://(freron\.com|example\.com)/.*"
</code></pre>
<p dir="auto">Hmm, it appears I've “forgotten” to document this. Maybe because I didn't really finish this feature. I would have liked to also handle a <code style="background-color:#F7F7F7; border-radius:3px; margin:0; padding:0 0.4em" bgcolor="#F7F7F7">MmDisallowedImageURLRegexp</code>. Let me know if you need that.</p>
</blockquote>
<p dir="auto">Hey, that’s great. It means I’ll have to deal with a long, ugly regular expression, but I can tolerate that I think. I don’t think I need a deny pattern, since deny is MailMate’s default.</p>
<p dir="auto">Thanks a lot!<br>
