Symptoms

---

If an email sent from ServiceNow contains an attachment, and if the attachment's filename is greater than 50 characters, their attachment name is observed as

ATT*.dat

in Lotus Notes email clients.

Release

---

All ServiceNow releases.

Environment

---

Lotus notes should be used by the end users.

Cause

---

An email that contains an attachment filename of Report containing a very long filename with more than 60 characters.csv would be composed like following example within the email headers:

Content-Disposition: attachment; 
    filename*0="Report containing a very long filename with more than 60
 cha"; filename*1=racters.csv

This composition conforms RFC2231, and utilized for handling long and international filenames. The issue seems to stem from Lotus Notes not supporting RFC2231: 3. Parameter Value Continuations extensions.

Resolution

---

You can either:

• Ask Lotus Domino/Notes administrator to upgrade the clients to IBM Notes Feature Pack 9
• Or if it's a scheduled report sending the attachment(s), change the report title to fewer characters, so an attachment with shorter names will be delivered to recipients.
