Here is a way to do the job with Notepad++:

• Ctrl+H
• Find what: ^.*?(?:user5@other\.com|([^\s,:]+@[^\s:,]+)).*?$
• Replace with: (?1$1:)
• CHECK Match case
• CHECK Wrap around
• CHECK Regular expression
• UNCHECK . matches newline
• Replace all

Explanation:

^                           # beginning of line
  .*?                       # 0 or more any character but newline, not greedy
  (?:                       # non capture group
      user5@other\.com      # literally
    |                     # OR
      (                     # group 1
        [^\s,:]+            # 1 or more any character that is not space, comma or colon
        @                   # @
        [^\s,:]+            # 1 or more any character that is not space, comma or colon
      )                     # end group 1
  )                         # end group
  .*?                       # 0 or more any character but newline, not greedy
$                           # end of line

Replacement:

(?1         # if group 1 exists
  $1        # take it
  :         # else, nothing
)           # endif
