We use easendmail SMTP with the easendmail service to send out mail notifications.

Recently, we have noticed TLS failures due to no shared ciphers or TLS 1.2 support.

Is TLS 1.2 going to be supported?

Hi, easendmail service uses system default SSL/TLS policy, so it depends on the Windows version, what is your windows version?

1. You must use .NET 4.0 or later version
2. add the following codes before SendMail or Connect server.

Code:

System.Net.ServicePointManager.SecurityProtocol = 
SecurityProtocolType.Tls | SecurityProtocolType.Tls11 | SecurityProtocolType.Tls12;


3. If above solution doesn't work, try to add the following register keys (very important)

Code:

Key  : HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\v4.0.30319 
Value: SchUseStrongCrypto
Type: REG_DWORD
Data : 1

Key  : HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\.NETFramework\v4.0.30319
Value: SchUseStrongCrypto
Type: REG_DWORD
Data : 1

EASendMail 7.5.0.1 supports TLS 1.2 very well, but if you use it on Windows 2008/7/2008R2, please add TLS support like this:
