Re: failure notice in mailwatch

Your problem is likely clamd. The /var/log/maillog would reveal what is going on.

You are also on v3, and I'm surprised it is still even functioning.

Re: Can I (should I) suppress DMARC report transmission?

The DMARC reports are controlled with cron jobs that you can optionally disable. /etc/cron.daily/eFa-Daily-DMARC is probably the one you want to examine. Comment the line mentioning /usr/sbin/opendmarc-reports

Re: IPv6 outgoing relay

Yeah this is a bug. The PeerList needs to be comma separated. You can work around it by using brackets for the IP portion and editing /etc/opendkim.conf to comma separate the entries. I'll prepare a fix.

Re: IPv6 outgoing relay

Are you setting that in eFa-Configure? If so, I bet we have a bug here. Let me check into it.

Try enclosing the IPv6 address in square brackets.

Re: PDF attachment converting to Base64 plain text

Well, I received the test email. It shows the partialMessage.bin as expected in the MailWatch UI (no filename defined, just a MIME type). When I received the email, the .ics file was intact. I also released the email a second time, and compared the attachment mime part with a sha256 hash: e56de70afa...

@shawn Until now we can repeatable create a Zoom (https://zoom.us/) invitation for a video meeting. When sending such an invitation via local outlook to an EFAv4 protected mail server, this email gets there but with a partial message inside EFAv4 but delivers correct to outlook as you wrote in your...

Re: PDF attachment converting to Base64 plain text

Well, this gives me something to work with. I'll sign up for Zoom and run some tests. I don't have an O365 tenant, but maybe we can start here and see what may be happening. Maybe something is triggering a reconstruction of the mime parts during normal delivery and causing it to be reinserted incorr...

Re: PDF attachment converting to Base64 plain text

I did see where someone mentioned that releasing the mail from the UI leaves it intact, maybe this would be a way to capture one? Release it and get me a a raw copy with headers?

Re: PDF attachment converting to Base64 plain text

If you want me to fix this, then I need a good sample of one intercepted prior to it being processed by the system so that I can isolate what is leading to this problem. Under normal conditions a partialMessage.bin should not show up as such on a client, even though it shows up in the appliance that...

Re: PDF attachment converting to Base64 plain text

partialMessage.bin is normal behavior for MIME parts with a mismatched size, which is all-to-common with PDF attachments. What is not normal is this getting passed along to the client. I'm accepting samples to troubleshoot this further.

Re: Use NAMED instead of UNBOUND for DNS

In the next update I'm going to separate the eFa-Monitor cron config and code so that we don't touch the monitor items entries. You will need to modify it one more time after this is done, so just be prepared for that.

Re: Use NAMED instead of UNBOUND for DNS

Does your network definition include DNS entries? That may be why /etc/hosts is getting overwritten.
