Hooker:Email Security
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:
- Program directory.
- Windows directory.
- 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 package is not included with the program by default.
You are advised to check for laws or regulations which may apply to you.
