Good afternoon Gerry
Over the past few weeks we have received bounce back emails from 0365 which relate to a Bare Line Feed issue. Victor has posted the following on topic "Bare line feeds (Email Issue)" the following:

Just a quick update on this issue. Our investigation so far reveals the issue to be isolated to emails which are using templates (specifically the CK Editor we are using when designing email templates). All other outbound emails (such as email sent from our mail interface and email sent using default and not edited templates) are not affected. This is not caused by any change we have done recently in Hornbill.
For Office 365 users it occurs because until recently, Office 365 automatically removed bare line feed characters from mail to help it get delivered to recipients using email servers that don’t support chunking and the BDAT command (such as Hornbill).To comply with RFC 2822, Office 365 no longer removes bare line feeds from messages. As a result, messages sent to users from Hornbill may be more likely to be rejected.
For other mail services users (e.g. MS Exchange) the issue could occur due to SMTP connector changes whereby the connector is now configured to reject bare line feeds.
Currently we working to get Hornbill mail in line with RFC 2822 requirements (https://forums.hornbill.com/topic/10012-dkim-for-outbound-email/).
For the time being we suggest the following possible workarounds:
create an inbound transport rule on your mail server to append a disclaimer to the messages from Hornbill. The disclaimer will append the expected CR-LF combination to the message so that it can be delivered. This disclaimer may consist of a single character such as a period or a dash (https://support.microsoft.com/en-us/help/2998901/-smtpsent.barelinefeedsareillegal-ndr-received-by-exchange-online-or-eop-users-in-office-365-dedicated-itar).
avoid the use of email templates which have been edited in the email template editor - CK Editor - (out of the box templates which have not been edited should not have this issue).
We currently use templates to notify our customers regarding updates, 3 strike rules & general correspondence, which was set up by the Consultants team. Because Hornbill are not yet inline with the RFC 2822 requirements our customers can not receive our emails. Am I right in saying that the templates out of the box (untouched) shouldn't be affected? If so can our templates be reset back to the default and re-created?
