zabszk / csharp-smtp-server Goto Github PK

In the headers collection all header values start with a white space

The subject is not decoded (when it is encoded using the Mime Encoded Word encoding according RFC2047)

The IMessageTransaction interface and implementations do not implement BCC and the underlying server code does not parse the BCC addresses of the email. Instead the address are added to the To address collection.

Hi,

how to stop a running Server?

I'm using Couchbase as database. Couchbase requires the nuget Packet "DnsClient", your CSharp-SMTP-Server requires your zabszk/DnsClient. Both have the namespace of "DnsClient". That way either one (Couchbase or CSharp-SMTP-Server) will always error out.

A possible fix would be to move the DnsClient into a namespace prefixed with zabszk.

Unhandled exception. System.TypeLoadException: Could not load type 'DnsClient.DnsClientOptions' from assembly 'DnsClient, Version=1.3.2.0, Culture=neutral, PublicKeyToken=4574bb5573c51424'.

The IMessageTransaction interface and implementations do not implement Subject and the underlying server code does not parse the subject of the email.

LOGIN authentication must be set in some scenarios the login argument sends user at the same time

The IMessageTransaction interface and implementations do not implement CC and the underlying server code does not parse the CC addresses of the email. Instead the address are added to the To address collection.

Issue Description:
When our application is receiving an email from an Exchange Server, it throws the following exception:

[Client receive loop] Exception: System.ArgumentOutOfRangeException, Length cannot be less than zero. (Parameter 'length').

This issue persists even if the SPF check is disabled. Unfortunately, we do not have more detailed information at this time, and it appears to be related to SPF checks or email handling.

Steps to Reproduce:

1. Receive an email from an Exchange Server.
2. Observe the application's behavior.

Expected Behavior:
The application should handle incoming emails from the Exchange Server without any exceptions.

Actual Behavior:
The application throws a System.ArgumentOutOfRangeException exception with the message "Length cannot be less than zero."

Additional Information:

• The issue appears to be related to SPF checks or email handling, but more specific information about the cause of the problem is not available.
• This issue might be related to the specific content or structure of emails received from the Exchange Server, but we need assistance in diagnosing and resolving it.

Environment:

• Application version: 1.1.5
• Operating System: Linux and Windows
• .NET Framework version: net7.0

Steps Taken to Resolve:

• We have already disabled SPF checks to see if it resolves the issue, but it persists.
• Reviewed logs and code for potential issues, but the root cause is unclear.

Hey,

Would you mind setting this up as a Nuget package?

The IMessageTransaction interface and implementations do not implement an Attachment collection and the underlying server code does not parse the attachments of the email.

Hi everyone,

I'm trying to use this library in a docker container on Linux.

the library is starting successful but when it comes to receive a mail it's throwing this exception:

[Client receive loop] Exception: System.IndexOutOfRangeException, Index was outside the bounds of the array.

Any Idea?

Thanks in advance
