You can do this by using a regex search/replace.
At the bottom, select Regular Expression.
In the Search for entry, you type in: ..@.
In the Replace with, you type in **@*
Then press the button Replace All
This works because Regex searches will only replace if its search criteria matches exactly. The match is explained as follows:
..@.
There are 3 dots and an @
:
@
has no special meaning in regex so it means a literal @..
means any character, exactly once. By writing..
it means 2 characters of any kind, as long as there are 2 characters.
