Aspose.Email giving errors while reading emails from email server


#1

Hi Support,

We are using Aspose.Email(version 17.2.0.0) to read emails from email server.
We are getting a crash on a production server, below is the details:

@munishOnguard

We have tested with latest version of our API i.e. Aspose.Email for .NET 18.11 and found no issue with reading emails from mail server. Can you please share the details of you work environment, which version of .NET is in use and please also mention the details of OS as well.


#5

Hi Muzammil khan,

Thanks for the reply. This is also working for our other customers. This occurs only one of our customer. Please suggest the reason of this exception.


#6

@munishOnguard

It looks like compatibility issue with work environment that’s why we need following details for further investigation.

  1. .NET SDK Version
  2. Operating System

@munishOnguard

Thank you for your feedback.

The log shows that 0 email exist in inbox. We have tested the IMAP with latest version of our API and it is working fine. So, It is requested to kindly check with latest version and if the issue still exist then share your code with us so that we could investigate in detail.

Moreover, please also mention the following details:

  1. .NET SDK Version
  2. Operating System that you are using

#9

Hi MuzammilKan,

Thanks for the reply.

We already using latest Aspose dll in our latest version of software, but this issue occurs in our older version, same version is working fine for some other customer who is using same version. We can’t upgrade to latest version.


#10

@munishOnguard

We can only suggest and test the latest version of our API and if there would be any issue in current version then that would be addressed in later ones.

Moreover, as you have mentioned that the same version is working with some other customers and for that customer where it is not working, you may need to check compatibility with .NET SDK.

Hi,

I am getting below errors:

We have logged this issue with ID “EMAILNET-39255” for further investigation. You will automatically be informed here once we have more information to share.


#16

@munishOnguard

We have investigated this issue and we are still unable to reproduce this issue. It looks that you are using outdated version (17.2.0.0) of our library which was released 2/16/2017. Since then many changes were added so It may affect on results.

Moreover, we have simplified your code as follows:

client.SelectFolder(ImapFolderInfo.InBox);
ImapMessageInfoCollection messageList = client.ListMessages();
foreach (ImapMessageInfo info in messageList)
	client.FetchMessage(info.UniqueId);

Furthermore, please feel free to write back to us if you need additional information.

Hi MuzammilKhan,

Thanks for your reply,

Simplified code is same what we have used, so there is no difference.
Also, we are sure that the exception is raised from Aspose dll.
