Summary

FileMaker 10 Send Email Error 1506 with Large Attachment

Description of the issue

We spent several hours today tracking down a problem with the Send Email script step in FileMaker Pro 10.0v3.  We are using password-authenticated SSL SMTP to a gmail account.  The problem is that Send Email throws an error 1506 with attachments over about 550KB.  If no attachment is included or if the attachment is smaller than the threshold no error occurs.  Even with the error, the email and the attachment *are* successfully sent. We tested the same emails and attachments with a different mail server (CommuniGate Pro) using an authenticated but non-SSL connection and there were no error codes.  I don't know if this is a problem just with the type of mail server that gmail uses or if it is related to SSL because we were not able to test SSL and non-SSL against the same server.
