Mailsploit problem in responce of ENVELOPE

[TACHIBANA Masashi]

Hi,

I'm sorry, I had been tested by miss From/Reply-To,

If From/Reply-To addresses are bellow:

 From: =?utf-8?b?c2VydmljZUBwYXlwYWwuY29tPGlmcmFtZSBvbmxvYWQ9YWxlcnQoZG9jdW1lbnQuY29va2llKSBzcmM9aHR0cHM6Ly93d3cuaHVzaG1haWwuY29tIHN0eWxlPSJkaXNwbGF5Om5vbmUi?==?utf-8?Q?=0A=00?=@mailsploit.com
 Reply-To: =?utf-8?b?c2VydmljZUBwYXlwYWwuY29tPGlmcmFtZSBvbmxvYWQ9YWxlcnQoZG9jdW1lbnQuY29va2llKSBzcmM9aHR0cHM6Ly93d3cuaHVzaG1haWwuY29tIHN0eWxlPSJkaXNwbGF5Om5vbmUi?==?utf-8?Q?=0A=00?=@mailsploit.com

ENVELOPE will come bellow:

A01 UID FETCH 25 (ENVELOPE)
* 5 FETCH (UID 25 ENVELOPE ("Fri, 08 Dec 2017 09:44:35 +0900" "test3" ((NIL NIL "=?utf-8?b?c2VydmljZUBwYXlwYWwuY29tPGlmcmFtZSBvbmxvYWQ9YWxlcnQoZG9jdW1lbnQuY29va2llKSBzcmM9aHR0cHM6Ly93d3cuaHVzaG1haWwuY29tIHN0eWxlPSJkaXNwbGF5Om5vbmUi?==?utf-8?Q?=0A=00?=" "mailsploit.com")) (("dev1" NIL "dev1-bounces" "example.com")) ((NIL NIL "=?utf-8?b?c2VydmljZUBwYXlwYWwuY29tPGlmcmFtZSBvbmxvYWQ9YWxlcnQoZG9jdW1lbnQuY29va2llKSBzcmM9aHR0cHM6Ly93d3cuaHVzaG1haWwuY29tIHN0eWxlPSJkaXNwbGF5Om5vbmUi?==?utf-8?Q?=0A=00?=" "mailsploit.com")) (("user1" NIL "user1" "example.com")) (("dev1" NIL "dev1" "example.com")) NIL "<20171206084846.0000478C.0596 at example.com>" "<20171208004435.00006B4F.0014 at example.com>"))
A01 OK Fetch completed (0.000 secs).

It seems correct response.

Thank you.
