Re: HTML email being converted to Plain Text

Thanks for your help, it pointed me in the right direction. There was a setting in Exchange that was causing HTML emails to be sent in Microsoft's TNEF format, with a winmail.dat attachment. I was able to disable that using the Exchange Management Shell command: Set-RemoteDomain -Identity thedomain ...

HTML email being converted to Plain Text

HTML emails sent from Exchange 2016 through eFa are being converted to plain text. Images in the signature show up as attachment, things like bold, italics are lost.

This behaviour appears to have started around a month ago.

Is there a setting I should check?

Disable SPF check for outbound mail

I have an Exchange 2016 server using eFa 4.0.4 hosted in a VPS as a smart host. Recently I have made my SPF checking rules more aggressive by increasing SPF_FAIL to 7, as I find enforcing SPF checks almost totally eliminates the remaining spam, and in my case has not impacted any valid senders. Howe...

Re: sa-update fails

Workaround: PERL_MM_OPT='' sa-compile is PERL_MB_OPT defined in your environment anywhere? Hi Phil, seems to have taken me a while to loop back around to look at this issue again, but I tried your workaround and it seems to have worked! PERL_MB_OPT was defined as the last line in .bashrc PERL_MM_OP...

Re: SA Learn error

I applied the changes mentioned in Henk's first post above, and all seems well. There's no error in the GUI any more.

Is there a way to determine if Razor is working, such as a command that will tell me which emails I've submitted?
