Email security options allow the use of encryption when communicating with the mail server.

Security options

Available encryption options:

  • STARTTLS – Implicit encryption which allows a non-encrypted connection to be upgraded to an encrypted connection. [1]
  • SSL/TLS – Explicit encryption which is to be used with servers which expect the entire communication to be encrypted from the start. [2]

Default SMTP ports:

Security option Default port
None 25
STARTTLS 25
SSL/TLS 465

Note: You should confirm the correct settings with your email service provider because they could be using a non-default configuration.

OpenSSL library

The use of encryption options requires OpenSSL library to be installed on your system.

You need to put ssleay32.dll (or libssl32.dll) and libeay32.dll from the OpenSSL package into one of these locations:

  1. Program directory.
  2. Windows directory.
  3. Any other location in the %PATH% environmental variable.

You can download OpenSSL package here:

http://indy.fulgan.com/SSL/
https://slproweb.com/products/Win32OpenSSL.html
https://www.openssl.org/community/binaries.html

Use the package that matches the architecture of the program, i.e. openssl-x.x.x-i386-win32.zip.

Why is it not included?

Use of strong cryptography software is illegal in some parts of the world. Therefore, OpenSSL library may not be included with the program by default.

As of Hooker v3.3.2 Beta, OpenSSL library is bundled with the program, but may be removed if Email Security options are not used.

You are advised to check for laws or regulations which may apply to you.
