Through PCRE verb (*SKIP)(*F).

<[^<>]*>(*SKIP)(*F)|[A-Z0-9._%+-]+@([A-Z0-9.-]+\.[A-Z]{2,4}|[A-Z0-9.-]+)

DEMO

<[^<>]*> matches all the tags and the following PCRE verb (*SKIP)(*F) makes the match to fail completely. Then the regex engine tries to match the pattern which was at the right of | symbol against the remaining string.

$re = "/<[^<>]*>(*SKIP)(*F)|[A-Z0-9._%+-]+@([A-Z0-9.-]+\\.[A-Z]{2,4}|[A-Z0-9.-]+)/mi";
$str = "<div data=\"[e-mail],[e-mail]\"><a href=\"[e-mail]\" > [e-mail], <b>[e-mail]</b> other text, [e-mail], ,<i>[e-mail]</i></a></div >\n";
$subst = "[---]";
$result = preg_replace($re, $subst, $str);
echo $result;

Output:

<div data="[e-mail],[e-mail]"><a href="[e-mail]" > [---], <b>[---]</b> other text, [---], ,<i>[---]</i></a></div >

[A-Z0-9._%+-]+@([A-Z0-9.-]+\.[A-Z]{2,4}(?![^<]*>)|[A-Z0-9.-]+)(?![^<]*>)

Try this.See demo.

$str = "<div data=\"[e-mail],[e-mail]\"><a href=\"[e-mail]\" > [e-mail], <b>[e-mail]</b> other text, [e-mail], ,<i>[e-mail]</i></a></div >";
$subst = "[---]";

$result = preg_replace($re, $subst, $str);

Output:<div data="[e-mail],[e-mail]"><a href="[e-mail]" > [---], <b>[---]</b> other text, [---], ,<i>[---]</i></a></div >
