Hi!
After the latest update Pegasus Utility for Mac version: 4.00.0000.08 (C01)
on system 10.12.5. I get errors on the mailserver:
Error: 550 5.6.11 SMTPSEND.BareLinefeedsAreIllegal; message contains bare linefeeds, which cannot be sent via DATA and receiving system does not support BDAT
smtp.office365.com
port: 587
Mail doesnt get delivered, I think that a external spamfilter that complain.
Anyway to fix this?
Regards
Mikael
Hi Mikael,
Thank you for contacting Promise !
We have not received any issues reported when using Office 365.
Could please confirm if the issue happened only after updating the utility to the latest version ? If yes, can you uninstall the Utility and try with the older version to see if it works.
Also , can you try with any other email address and see if the notification works ?.
You might have to open a case @ https://support.promise.com for troubleshooting this issue further.
Thanks !
Hi!
Downgraded 3.20.0000.15, I got the same error. When using another emailaddress thats doesnt get checked by external spamfilter it works. It looks like 365 did remove bare line feeds but now that changed that setting and doesnt remove them any longer, and now spamfilter rejects the message. But if Pegasus whould send mail without bare line feeds I shouldnt have the problem.
Did find this article:
https://support.office.com/en-us/article/Fix-email-delivery-issues-for-error-code-5-6-11-in-Office-365-81dafee7-26af-4d79-b174-8f78980dfafb
Thats says:
Until recently, Office 365 automatically removed bare line feed characters from mail to help it get delivered to recipients using older email servers that don’t support chunking and the BDAT command. The support for BDAT is required by the email industry standards referenced in RFC 1830. In an effort to better support security standards, like DomainKeys Identified Mail (DKIM), Office 365 no longer removes bare line feeds from messages. As a result, messages sent to users with older mail servers may be more likely to be rejected.
With some solutions:
1. Use a different email program, one that doesn't add bare line feeds to the message, such as Outlook on the web, to send the message.
Or
2. Some email servers support the ability to enable or disable bare line feed rejection. Exchange Server, for example, includes the Receive connector setting BareLinefeedRejectionEnabled. If the email recipient is using Exchange Server, their admin could disable the BareLinefeedRejectionEnabled setting on the server's receive connector. See the article Set-ReceiveConnector for more information.

Mikael
