How to stop promotion/add using SMTPClient to send email

Aspose.Email Product Family

Hi Aspose Team,

I am using SMTPClient to send a Task Email. Please see the below code.

// Create instance of SmtpClient class by giving credentials

SmtpClient smtpClient = new SmtpClient(“host”, “abc@domain.com”, “abc@123”);

smtpClient.UseTnef = true;

smtpClient.Send(eml);

Suppose I input Task Subject as “SMTPClient” them it itself added (Aspose.Email.Evaluation).

Please see the attached highlighted snap.

My question is how to stop this kind of promotion/add for the Aspose API.

I tried to set UseTnef as false then it’s works fine, But i want to sending messages as TNEF.

Also if i use IEWSClient as an altenate then no such issue in that case and works fine. nothing would be added to the Subject.

Thanks and Regards

Hi Vipin,


Thank you for your inquiry.

I have tested this issue at my end with SmtpClient using the latest version of Aspose.Email for .NET 5.2.0. No such issue is raised with my license initialized properly at the start of application. I would request you to please recheck the license initialization at your end. If the issue still persists, please send us your sample console application that we can use the investigate the issue at our end and assist you.

Hi Muhammad,


It’s reproduced each n every time. i attached screenshot already.
Also why it is showing Unknown sender, Please see the screenshot attached with this post.
I am using a user account with the credential to send a task using SMTPClient.

if i set the UseTnef property to false then the first problem is resolved. unknown sender still exist.
Is it with the Trial Aspose dll?

Thanks,
Vipin

Hi Vipin,


Thank you for sharing your feedback.

1. I was able to reproduce the issue of “unknown sender” while setting UseTnef=True using SmtpClient. The issue has been logged as EMAILNET-34765 in our bug tracking system for further investigation by our product team.

2. The evaluation warning appears only when the license file is not applied. If a license is applied properly, no such evaluation warnning appears in the email subject. In this special case, the evaluation version information should not have vanished when UseTnef is set to False. We shall further investigate the issue at our end for correction of this behavior at our end. In the meanwhile, if you want to test the API features without any evaluation limitations, you can get a 30-day temporary license free of cost.

Hi Vipin

We have logged the issue of non-inclusion of evaluation limitation message as EMAILNET-34768. The evaluation limitation message should have been shown when UseTnef=false and no license is set. It will be further investigated by our product team for resolution and we shall notify you here once there is some information available about this issue.
