I am running PHP List 3.4.7 on Windows Server 2012 with a localhost SMTP server (via PHP Mailer). Also tried labeling SMTP server directly in the PHPlist config file without a difference in the result.
I am getting a consistent bounce error with certain recipients warning of an inability to receive “bare linefeeds”. I can’t find any documentation or workarounds for this. This appears to happen with Office 365 recipients which probably means a problem for a significant number of people. Consistent issue over multiple versions of the PHPList software.
I don’t know how to get access to the email in its raw form to spot the problem. Are there basic steps I should take to resolve this with PHP List? I haven’t done anything to the code, etc. Nothing in the documents or config seems to speak to this issue at all.
