Is there a size limit when uploading attachment in iNotes?

I have a user trying to send an attachment in iNotes. The attachment is 1mb. When trying to send the attachment, we get the error:

Is there a size limit to attachments in iNotes? If so, can it be changed?

Thanks

I just looked at the config document in the iNotes section and this is what is set:

Mail

Minimum mail polling time

5 minutes

When sending mail, set format to:

Let user decide

Name resolution and validation:

Enabled

Maximum attachment size (kb):

150000

Mail threads:

Enabled

Subject: Solved…

Rebooting the server resolved the issue.
