Re: Huge number of DOMAIN UDP traffic to/from EFA

About a hundre each day - but I do get many that are RBL'ed or otherwise turned away.

As for remote sources - I have no data on that.

Huge number of DOMAIN UDP traffic to/from EFA

Re: [howto] Installing and using opendkim with EFA 3.0.0.7

Hi again. This is quick write-up of how I switched from one to two postfix instances primarily to solve proper dkim-signing of outbound email together with the additions of the EFA spam-links. The background for doing this was that emails were being signed by dkim before EFA inserted the links hence...

Re: Protect privacy

What are trying to gain from that? E-Mail in itself isn't encrypted and sending confidential information via non-encrypted e-mail is a failure right from the start. I think the appropriate way to handle these issues are policies and audits. Budy, I fully agree with your statements. Don't try to tur...

Re: Protect privacy

Further elaborating on this topic: would it be possible to encrypt the content in any way?

Re: Protect privacy

If I were attempting this, I would... 1) Create domain admins for your mail domain (not full admins). 2) Modify the code in detail.php starting on line 533 by removing most of the logic and restrict to admin only: Good point indeed, thanks. I would however like a possibility to block all admins - m...

I'll write up a summary this weekend. Nothing to complicated so should be an easy ride. :)

Protect privacy

Hi there. I have a concern with the quarantine functionality of EFA: On one side I love it because it enables the addition of "Report this as spam" but on the other it poses a privacy-issue wherein I - as the local sysadmin - have the option to read all messages that comes through my serve...

Very interested in your work. Standing up a second postfix instance for signing is a brilliant idea and moves signing after the mailscanner message mods.

I think we should consider your implementation method of opendkim.
Let me know how I can contribute and I will do my best.

That is good news.

Will it work with in-line signing?

@ulfthomas: I just wanted to confirm that I had the exact same problem and solution. I didn't find any other option than to completely disable inline signing.

Re: [howto] Installing and using opendkim with EFA 3.0.0.7

Hi all. I just found EFA and implemented it with success straight away - and so far I do love it. At the moment I am combating OpenDkim and I have been able to make it work - but I was forced to disable in-line signing. Is there any way to run dkim whilst having signing enabled? Can the order be alt...
