Hello Everybody,

I encounter a problem when using StartTls () for the Imap component.
We authenticate ourselves using authentication cards and it sometimes happens that we have to change the card in order to retrieve mails on another account.
The connection to the first account with the authentication card works fine. By cons when I change card and I try to authenticate with this card for his associated account I have an error and he can not find his information.
I have verified that in the certificate store all were in place.
If I relaunch the application and I authenticate myself with this famous card on the corresponding account all work niquel. The error occurs after a first authentication with another card / account.
we are using version 9 of the components.
If you have an idea, I'm a taker because I don't know what to do anymore!

Sorry for my awfull english

Hi,

I guess you're using client certificates for authentication. You can check if your code is correct by making some simple test sample.

Code:

Imap imp = new Imap();

imp.Log.Enabled = true;

imp.Log.Filename = @"C:\Temp\log.txt";

imp.Log.Clear();

imp.SslCertificates.Client = new Certificate(@"C:\my1.pfx", CertFileType.Pfx, "secret");

imp.Connect(...);

imp.StartTls();

imp.Disconnect();

imp.SslCertificates.Client = new Certificate(@"C:\my2.pfx", CertFileType.Pfx, "secret");

imp.Connect(...);

imp.StartTls();

imp.Disconnect();

Does it work this way? If not, does it work if you try my2 first and then my1? You'll need to collect as much info as possible, with different scenarios. Also, please note that we support only the current, up-to-date version. So please make sure you tried the latest version.

Regards,
Alex
