To elaborate on the previous note...As a short-term fix, I upped the size of NOTIFICATION_REPLIES.SUBJECT from 100 to 500 characters. Presumably, the offending inbound note was slurped in, generating new outbound notes to alertees. Because the inbound note had a long subject line, so will the outbound note. If the SUBJECT column for acs-mail-lite is 100 chars, that would explain the errors that prompted Don's post. [I would check directly but don't have ssh access at this moment].
