FETCH Message via IMAP, use BODY[] rather than RFC822

Aspose.Email Product Family

Hello
Refer to the IMAP activity log, Aspose using following pattern when fetch messages:
e.g.

AE_2_1_0020 UID FETCH 4156 (RFC822)

where 4156 is one of the message id.
But we met a older environment which cannot compatible with “RFC822” words. the server will return wrong response if fetch messages with “RFC822”
And we do some testing, if the command is

UID FETCH 4156 (BODY[])

which use “BODY[]”, the server will return correct response.
The issue is that the server is too old and cannot handle RFC822, but it’s hard to do an update to the server.
Is there any method or properties we can using and then we can fetch message with “BODY[]” rather than “RFC822”?
Thanks in advance,

Hello,
I’m using Aspose.Email in C#.
the method i’m using is
> var AsposeImapClient = new Aspose.Email.Clients.Imap.ImapClient(this.IMAPAddress, this.IMAPPort, this.UserName, this.Password, Aspose.Email.Clients.SecurityOptions.SSLAuto);

AsposeImapClient.ReadOnly = true;
AsposeImapClient.Timeout = DownloadTimeOut * 60 * 1000;
var messages = AsposeImapClient.ListMessages(“INBOX”);
…
//There is a message which id is “1”
…
var message = AsposeImapClient.FetchMessage(“1”);

Is there any parameter or option I can use when FetchMessages to make that the inner request command is like UID FETCH 4156 (BODY[])
because the server I’m working on cannot handle “RFC822”?
Thanks,
Ming.

Hello,
I saw the linked issue is closed. It means the issue has been fixed in release, right? But I’m not able to find any documents about the fix, e.g., how to use (BODY[]) rather than (RFC822) when using FetchMessage? Could you give any guide for this? Sorry I did not find any related parameters in any override in method FetchMessage in new version of Aspose.Email.
Thanks,

Hello @xieming95at163.com,

We added the SupportOldServer property to ImapClient.
Use it as follows to use (BODY[]) when fetching emails:

client.SupportOldServer = true;
