Sender mail adapter - filter emails by attachment?

Dear experts,
I have a sender mail adapter that picks an XSL (EXCEL) attachment from an incoming email and converts it (with a custom adapter module) to XML.
But now how can I make the adapter only process emails with XLS - attachments? In that Inbox I also have emails with HTML-attachments for example. And now my adapter also wants to process those messages.
In my adapter module that makes XLS to XML I see an exception in RWB but the message still gets through to SXMB_MONI where it gets stuck with a red flag.
Can I somehow tell the adapter to only process emails with XLS attachments?
Or can I stop the processing in the adapter module that converts XLS to XML?
Thank you for any input or ideas on this!
Best regards,
Peter
PS: I am using this code to convert XLS to XML:

Hello ChizzT,
Thank you for your idea. I went with this one and it worked.
Best regards,

Sender Mail adapter encounters MalformedInputException

I have a sender mail adapter that processes the attached .csv file. All is working fine. I use FCC in module to convert the attachment and pass to an IDOC adapter for processing in SAP system.
My problem is sometimes the sender mail CC fails with ...........
exception caught during processing mail message[1]; com.sap.aii.af.mp.module.ModuleException: Transform: failed to execute the transformation: com.sap.aii.messaging.adapter.trans.TransformException: Error converting Message: 'sun.io.MalformedInputException'; nested exception caused by: sun.io.MalformedInputException caused by: com.sap.aii.messaging.adapter.trans.TransformException: Error converting Message: 'sun.io.MalformedInputException'; nested exception caused by: sun.io.MalformedInputException
It only fails with some files. At the moment when we test we FORWARD the email to our email account. If I detach the failed email attachment and attach it to a NEW email it will then work.
So why does it not work when forwarding emails? But it works when I attach the same file to a new email and send?
Other threads for this error seem to point to encoding. But how do I know which to use. I currently use the following in my module config:
Transfer.ContentType     application/octet-stream;charset="ISO-8859-1"

I have this in my configuration:

Sender Mail Adapter with PayloadSwapBean

Hello Experts!
I have a Sender Mail Adapter receiving emails with attachments! I'm using PayloadSwapBean, because I have to manipulate (to do mapping) the XML attachment.
Sender Mail Adapter Configuration:
Default Interface Namespace = urn:mynamespace.com
Default Interface Name = abs_async_myInterface
swap.keyName = Content-Disposition
swap.keyName = Content-Description
swap.keyValue = attachment;filename="MailAttachment-1.xml"
swap.keyValue = MailAttachment-1
Well, my problems are:
1) Although my Default Interface Namespace is urn:mynamespace.com, sometimes the namespace that cames to SXMB_MONI is http://sap.com/xi/XI/System/Mail. In that case, an Receiver Determination error happens.
2) My XML can be the first (MailAttachment-1), the second (MailAttachment-2), the third (MailAttachment-3), or any other attachment position. Since my swap.keyValue is set to "MailAttachment-1", I'm able to pick the XML only if it is the first attachment.

Hi Julio,
Writing an Adapter Module for the same can make your task easy.

Security requirements on sender mail adapter

I have set up a sender mail adapter to fetch the email with attachment from MS exchange mail server. The sender mail adapter can process the attachment well and convert it to XML format. Now I have a new requirement to determine if the email comes from a particular user. I can see the FROM field in the payload "MailMessage" But I don't know how to get the value of this field. Any idea on how to set up the message mapping? Thanks in advance.

Before the sender mail adapter processes the attachment in the email, it need to determine the email is actaully from the business user not someone else on server. Cuz everyone can send email to the email address the mail adapter connects to, that is why this security issue comes from.
Basically when you fetch a email with attachment, in Sxi_monitor, you can see two field in the payload, One is MailMessage and the other is MailAttachment-1. In the MailMessage, you can see all the emial header fields, such as From, To, Subject, Content etc. I need to check if the FROM field is email address we allowed. That is basic requirements. Let me knwo if you want me to explain it further.

Email attachment name in sender mail adapter to the receiver file adapter

HI ,
Ths is regarding email to file scenario. I am trying to create file (in rceiver file adapter) with the same name as the email attachment that i read from mail sender adapter. I want ro use adapter module for this. I could find from blogs that there is module - GetAttachmentName - available that i can use for this in sender mail adapter.
Can you please let me know what whetehr i neeed to mention any module key and parameters for this.
I assume , i need to do following steps :Please confirm.
1. i can use this module - after payload swap module and before standard mail adapter module in sender mail adapter
2. select ASMA option in advanced tab in sender mail adapter
3. In receiver file adapter select ASMA option in advanced tab in sender mail adapter
4. Also select file name option in ASMA in sender mail adapter
Thanks,
Vamsi

Hi Vamsi,
your scenario is also described here: Re: sender mail adapter - attachment name
If you use the Module getAttachmentName, which is described here,
http://wiki.sdn.sap.com/wiki/display/XI/AdapterModulePI7.0GetAttachmentName
your scenario should work as you described it.
You just need to make sure that the Attachment Name that you read in the first place, is mapped to the Filename Attribute of the
Fileadapter (http://sap.com/xi/XI/System/File/FileName).

Sender Mail Adapter - forcing content as an attachement

Hi all,
We are using the Sender Mail Adapter to pull emails from the inboxes of some users of an exchange server. We use the Mail Package option.
We have noticed that the content of the emails are by-default added as attachments when there are no real attachments to the emails. However the content is not added as an attachment when one or more attachments are present in these emails.
Is there a way of forcing the Sender Mail Adapter to always add the content as an attachment and keeping the other attachments as well? and of course maintain the Mail Package message type as the main payload...?
Many thanks,
Aldo

Hi Stefan,
Thanks for your reply. I am glad to hear that I am wrong again )
In your opinion is it possible to force the Outlook Exchange server to add the content attachment every time? I mean by doing some configuration on it...?
The reason why we would like to do this is because when - in the content tag of a Mail Package message - we have MIME message parts that are of content-type text/html we are having problems in decoding the html back to a readable format.
To do this we use the apache QuotedPrintableCodec Java class.
This works fine when the content type of the message is just text/plain but we get an exception when we try with text/html.
The exception we get is:
org.apache.commons.codec.DecoderException: Invalid URL encoding: not a valid digit (radix 16): 13
I don't know if this is because of the two character sets we have in the payload (utf-8 and iso-8859-1) or if it is for other reasons...
If you could help me figure out how to forward any HTML email to another system in a readable format it would be great.
Thanks for your support,
Aldo

Dynamic file name of the attachment in sender mail adapter

Hi
I have configured a sender mail adapter which receives some attachments.
Right now the file name of the attachment is hardcoded to "MailAttachment-1" "MailAttachment-2" using the content-description from "AF_Modules/PayloadSwapBean" module.
I want to set it to dynamic ie. instead of "MailAttachment-1"... i want it with real name of the attach.
please suggest a solution w/o the need to develop a custom adapter module.
Thanks!
Regards,
Mariano.

Thanks Prateek,
Now, i can see that the name of the original file is into the content type named as text/xml; name"name of the file.xml" when i send the email from outlook.
If i send it from hotmail, this is not happend.
Do you know why happend this?
If i always would have the original name inside the content type, my problem will be solved.

Sender mail adapter - attachment name

Hi there
We have configured a sender email adapter to receive text/csv attachments and save them to a file system. What we are having a problem with is reading the attachment name. So we are using Dynamis Configuration to create the file name using the subject line - Which is not ideal. Ideally we would like to use the same name as the origianl attachment but haven't found any way of doing that. We even tried using Content-type in the Variable Header (XHeaderName1) suing variable transport binding but it doesn't show up in the Dynamic Config part of the SOAP message.
Is there any way of reading the name of the file attachment? We are on PI release 7.0.
Any help would be appreciated.
Cheers
Salil

Hi Vitor
There are 2 scenarios that I can think of -
1. You are saving the email attachment as a file. In that case use step 3 in the earlier reply to get the attachment name and save the file witht that name.
2. You are sending the XML straight to a receiver using HTTP, IDOC, JDBC etc. in which case you would need the attachment name much earlier that step 3. For that I guess you would have to write another adapter module on the sender mail adapter(at Position 3 where position1 = payloadswap bean, 2 = custom module to get the attachment name) and add an xml tag to your incoming message. These adapter modules are really powerful and are like user exits in ABAP. In that case you would have to change the Data Type in the Integration repository to reflect that extra tag. Here is some code from a module we wrote to totally change the structure of the xml coming in. The key thing to remember is this module is that you can read the whole message byte by byte. There might be smarter ways of doing it (like using the SAP XML parser factory class) but since I'm not a Java programmer I stuck to the basics. Here's the code( you could also look at the example given in sap help where they remove (or add I'm not sure) CR(carriage return) from CRLF (CR Line feed).

XI - Sender mail adapter - attachment as payload

Hi,
My scenario is Email -> XI-> ...
I am trying to send an email with an attachment. I want to XI process only the attachment as the payload.
How do I do ? What is the communication channel configuration ?
Thanks,

Sender "Mail" adapter - CSV file attachment

Hi there
I'm looking for some help in configuring a sender mail adapter that receives ".csv" files. I did read some blogs that mention using the "PayloadSwapBean" module to read the mail attachment instead of the mail content. My problem is to now convert the ".csv" file into a message. Is there a module that I can use ( is it the "MessageTransfomBean" ) and how. Any help would be appreciated.
Thanks
Salil

Hi Salil,
If you want to send a mail with a body and attachments, the message sender HAS to provide an XI message with attachments. I doubt a CSV file does justice.
As Renjith said you need to convert CSV to XmL.
A short description about the Standard Modules:
MessageTransformationBean is a standard module used to apply the XSLT mapping to the adapter module by using Transform.class ( This xslt mapping is done to create a mail package, Dont confuse with the actual mapping in your case this is NOT for converting csv to xml).
Also this module can be used to change the name and type of payloads by using Transform.contentType, Transform.contentDisposition, Transform.contentDescription.
PayloadSwapbean is a standard module for replacing payloads with other payloads (SWAP)
If you want to give each attachment a certain name use Parameters, swap.keyname for name of the payload and swap.keyvalue.
I Hope the use of standard modules is understood.

Sender Mail adapter configuration with attachment

Hi,
I read the below blog regarding the mail adapter
/people/michal.krawczyk2/blog/2005/12/18/xi-sender-mail-adapter--payloadswapbean--step-by-step
I have the same requirement but the attachment file is not an XML, it is CSV file so in the module tab if I change like below is it enough?
TRANSFORM swap.keyValue attachment; filename=u201DMailAttachment-1.csvu201D (I think MailAttachment-1 is the file name, am I correct?)
If I change like above is it ok? or any other thing is required, Could you please give me the inputs
Thanks
Ramesh

I have the same requirement but the attachment file is not an XML, it is CSV file so in the module tab if I change like below is
it enough?
PayloadSwapBean will ensure that the input to the mapping is from the attachment.....in the blog the attachment is in XML format and hence there was no need for any conversion.....yours is however a CSV file so you need to convert it to XML first and then do the further processing.....you can either use the MessageTransformationBean as shown in this blog:
/people/gabrielsagayaselvam.panneerselvam/blog/2009/08/31/solve-key-field-problem-using-structplain2xml-in-messagetransformationbean
Or write your own module code for the conversion.

Abhishek.

Using header paramter SHeaderX-MS-HAS-ATTACH in Sender mail adapter

I am trying to check if an e-mail contains attachment in reciever determintion
I set the Variable Header XHeaderName1 to be SHeaderX-MS-HAS-ATTACH
in Sender mail adapter
I added a condition in the receving determintation
XHeaderName1 = yes
I see the DynamicConfiguration tab in sxmb_moni and the value of SHeaderX-MS-HAS-ATTACH is "yes"
but the message fails with the error
No receiver could be determined
any ideas?

Hi,
In Receiver determination you need to set SHeaderX-MS-HAS-ATTACH = yes instead of XHeaderName1.
As far my understanding, in receiver determination you need to verify the condition with SHeaderX-MS-HAS-ATTACH = yes (check with syntax also ie. case sensitive and all)
Thanks

How to download / read text attachment in Sender Mail Adapter IN XI

Hi
I would like to know how to download / read text attachment in sender mail Adapter & sent same attachment to target system using file adapter.
Please help how to design / resolve this concept.
Regards
DSR

I would like to know how to download / read text attachment in sender mail Adapter & sent same
attachment to target system using file adapter.
Take help from this blog:
/people/michal.krawczyk2/blog/2005/12/18/xi-sender-mail-adapter--payloadswapbean--step-by-step
From the blog:
However in most cases
our message will not be a part of the e-mail's payload but will be sent as a file attachment.
Can XI's mail adapter handle such scenarios? Sure it can but with a little help
from the PayloadSwapBean adapter module
Once your message (attachment) is read by the sender CC, you can perform the basic mapping requirement (if any) to convert the mail message fromat to the file format.....configure a receiver FILE CC and send the message...this should be the design...

Abhishek.

Non XML attachment to XML in sender mail adapter

Hi,
I am working with sender mail adapter and usng payloadswapbean. My attachment is non XML and I need to convert it in to XML in order to mapping. How can I do that? Can someone explain if can I use MessageTransformBean for this purpose and if so, how?
Or any other method for doing this?
Thanks,
Rakesh

Is the attachment in text format? If yes, then after the usage of PayloadSwapBean, you may try using MessageTransformBean in the same module chain. And you will be able to convert it into xml format.

Different Attachment extension(.xls,.txt) in sender mail adapter

Hi Experts
Is it possible to use different type of attachment extension (e.g .xls,.txt) in the sender mail adapter?
My requirement is , the attachment in the mail adapter will be used as the main payload.So I am using PayloadSwapBean adapter module.
Currently I am using the following module key for .xls attachment and it is working.Configuration for .xls attachment is as follows
swap.keyName-Content-Disposition
swap.keyname-Content-Description
swap.keyName-Content-Type
swap.keyValue-attachment;filename="MailAttachment-1.xls"
swap.keyValue-MailAttachment-1
swap.keyValue-application/vnd.ms-excel.
Now, the attachment may be .xls or .txt file.
Now If I want to use .txt atachment then do I need to define all these parameter again and in that case what will be my content type for .txt file.
Your inputs required
thanks
Ayan

PayloadSwapBean will only convert the attachment as the main payload.
Yeah for reading excel file I have a separate custom adapter module.This is not in the scope of my question..
All I am asking , can .txt as well as .xls attachment be used in the same sender mail adapter.
If that is possible what will be my content-type for .txt or can I remove content-type and use only content-disposition and content-description so that any type of attachment it can recognise.
The momment I am specifying content-type , I am making it particular that only say .xls attachment , it will identify.
I hope I make you clear.Inputs required
Thanks
