Customer sending an email (with an attachment) to us.
Based on this bounce message only, which side is at fault here?

Thank you.

from the error log, it is oblivious that the bouncing is as a result of the recipient mail server restriction.
you can talk to your IT department either to increase the incoming mail attachment size limit or you can ask the client to send the attachment in couple of pieces.
your client can use the freeware portable software to split the attachment into small pieces and then you can use the same software to merge them once you received them into different pieces.

The attachment size was 6 MB (plus up to 30% increase during the process).
My send/receive connectors on Exchange server are all (globally) set to 30 MB.
I don't  have problems with any other customers.

I was also informed that the size limit on his send connector is set to 10 MB.
I just want someone to explain this bounce back message and how it makes sense?

I don't want them to split the attachment, I would rather get them to use my ftp site for large files.

Thanks.
there are two ways of limitation on receiving the attachments

you may also have issues with the transport limit.

All done in the past.
I don't  have any problems with other customers sending large files.
Was there more than one attachment to that message?

No.
Just one .dwg file.
I have tested sending a large .dwg file myself using my gmail account and it worked fine.
Any chance you have set send/receive size limits on the user themselves?

Gareth,

Yes. I had some individual mailboxes set to 20 MB in the past.
I just changed all of them to default.
If my server is at fault in this situation, could that be the issue?

Thanks.
