550 5.7.60 SMTP; Client does not have permissions to send as this sender

Cause

• Paperless Office, Form Maintenance may not have been set up correctly.
• The default email user setup in Company Maintenance does not have permissions from the SMTP server to email as the “From” E-mail account set up for Paperless Electronic Delivery
• The actual form’s Paperless Office Delivery Options settings has the wrong e-mail address
• The “From” e-mail address cannot be used due to security/rights restrictions on the SMTP server, or the address is not in the domain (this may occur to a change in domain or SMTP provider)

Resolution

Check Form Maintenance:
Confirm the “From” E-mail Address in P/L Form Maintenance is correct:

1. Open Paperless Office, Setup, Form Maintenance
2. Click, Form Entries (flashlight) button
3. Select the Company/Module/Document in question (XXX, S/O, Invoice)
4. Verify the From E-mail Address
5. Click, Accept

Check Form Code(s):
If Form Maintenance is setup correctly and the error still occurs, check the form code(s) in (for example) Invoice Printing:

• Example:
  1. Open Sales Order, Main menu, Invoice Printing
  2. Select, Form Code in question
  3. Select a Paperless Office Output which will “Electronically Deliver”
  4. Click, Electronic Delivery button to the right of the Paperless Office Output
  5. Verify the From E-mail Address is correct for this form
  6. Click, OK
  7. Repeat for other impacted forms
• Note: See the Related Resources section for more information.

Check with the SMTP server provider:

• The proper permissions may need to be set by the provider. Or, if they were previously set correctly, permissions may have been changed, unbeknownst to the user, and need to be changed back.
