We use the following c# code:
Pop3 pop = new Pop3();
pop.Settings.SslAcceptAllCertificates = true;
pop.Connect(serverName, 110, SslMode.None);
The Connect method takes half second if it is called from Windows Forms Application, but it takes 30 seconds if it was called from Windows Service. Tried several times.
Why is it? How can I or you fix this?
OS: Windows 7 Professional 64 bit
Rebex Components 2013 R2 v2.0.4981.0 (.NET 2.0)
Window Service uses .NET 3.5
When using other pop3 server with Implicit SSLmode and different port, it works well and fast.
