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.

[aaaa:bbbb:cccc:dddd::]/64

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...

Time is precious. I'll get back to this soon. Feel free to jump in and see what we are up against (it is a lot).

CentOS 8 is EOL; switching to CentOS 8 Stream is appropriate.

@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...

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...

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?

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...

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.

Did you work through these issues or need more assistance?

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.

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

Put your eFa into maintenance mode or modify the eFa-Monitor cron to exclude unbound.

Well, that's not good. It is most definitely infected. Time to do a bug hunt.

Fixed in commits https://github.com/E-F-A/v4/commit/cb27 ... 5dc7fa0c8c https://github.com/E-F-A/v4/commit/07a8 ... 696a2d3a8e

Benign, will fix.

Fixed

I'll tackle these two issues.

You also may want to clear the cache in unbound.

Code: Select all

sudo unbound-control flush_zone outlook.com
sudo unbound-control flush_zone protection.outlook.com
sudo unbound-control flush_zone mail.protection.outlook.com

Make sure unbound is running.

Code: Select all

systemctl status unbound

Edit /usr/bin/pyzor and replace the following at the top:

Code: Select all

#!/usr/bin/python -Wignore::DeprecationWarning

Code: Select all

#!/usr/bin/python3 -Wignore::DeprecationWarning

Code added in commits https://github.com/E-F-A/v4/commit/642f ... 4c182341c9 and https://github.com/E-F-A/v4/commit/086e ... d874f27473
