Good evening With eFA, when you setup the appliance, you have an account that can access the console however I need to add a second admin to be able to assist with changes on the console etc. How do I go about adding another user other than the account that was setup initially? Is this possible? I g...

Hi there From a previous post I found https://forum.efa-project.org/viewtopic.php?t=1462) I changed the options below from disarm to yes. I did 1 at a time until all the emails were shown correctly. Allow IFrame Tags = disarm Allow Form Tags = disarm Allow Script Tags = disarm Allow WebBugs = disarm...

Is there anyway to change the cipher to use 256 bits instead of 128 bits?

I did try updating the posfix config file and change the ciphers to high with a high list but no difference.

Mail coming in is 256 bits.

Thanks
Edward

yes sure, will send it in the morning

Here are the settings in the mailscanner.conf file:

Spam Actions = store
High Scoring Spam Actions = store
Non Spam Actions = deliver header "X-Spam-Status:No"

Thank you, I tested it earlier by changing mx records to Exchange directly and the mails are coming through fine. When i put eFa back, i get the emails as per my example.

It might be something small that needs to be changed I am guessing?

before mail would come from the internet to exchange and the emails were received without an issue.

eFA is now in front of exchange and only since the change does it do this to the emails with html content.

My customer receives html emails from various places however the entire body of the email has all the images removed and you only have url's to the images and text. Here is an example of an email: mydomain: Dahua Switch SWDA105, 4-Port PoE Switch Unmanaged mydomain: Dahua Switch SWDA105, Why not swi...

Anyone with feedback?

Hi

I have emails from some domains stripping the html content and only showing text.

I went and looked at MailScanner.conf and the setting "Convert HTML To Text = no" is currently set.

Which other line could be causing html content to be removed and replaced with text?

Thank you
Edward

Good morning I have this working. My MX records are not evenly weighted but it does cycle to the other one if i restart the main server for example. I implemented this last night so will give another update on how things are going over the weekend. Both eFa servers are setup the same, i just created...

Hi there

I see that my mail servers send to efa using TLS 1.2 however efa is not sending using TLS 1.2

I tried to update the postfix config file and add in !TLS1.2 after !SSLv3 but it seemed to stop mail flow.

Can you advise if I need to update all the smtpd lines or which is the correct one?

Hello Ulrich

Thank you,
I found some more than what I had and implemented it but it blocked outlook.com and gmail.com as they are on blacklists so had to remove the 4 entries i added. Will put them back as soon as i get the go-ahead again.

Hi Nicola

I tried to download the file but the page cannot be displayed.

Will this block google/outlook.com as i implement two rbl's today and had to remove them as Microsoft and Google IP's are blacklisted.

Hi Ulrich

It is public. Where would this be added in the postfix config to do a check on an IP for blacklisting?

Kind Regards
Edward

Good morning

I have certain emails coming through and ESET is catching it after eFA passes it onto Exchange.

How do i block emails as per the attached and have eFA check that IP's are on a blacklist?

Thank you
Edward

Thanks very much.

that worked and now quarantine only shows spam etc.

Thanks for the response, the single line worked.
I see that most of the information is already in the file at the end, I just added in some more rbl entries.

Hi Ulrich Thanks for the quick response, so if I changed the No to a Yes would this stop all mails logging to quarantine? 'Non Spam Actions = store deliver header "X-Spam-Status:Yes"' I did do a search and found someone mention 3 items that can be added to the file but I get errors saying ...

Maybe consider adding these by default to the main.cf file in future deployments? the info can be found here... https://wiki.centos.org/HowTos/postfix_restrictions all 3 of these go into main.cf # /etc/postfix/main.cf # HELO restrictions: smtpd_delay_reject = yes smtpd_helo_required = yes smtpd_hel...

Good afternoon.

I have eFa running at my customer and they see that all emails are showing under quarantine. Is this behaviour by design?

My second questions is does eFa do lookups if a domain is blacklisted? If so where do i enable this?

Thanks
Edward

Thanks for the response Shawn

I configured point A and B and see the line in that file for spam assassin was already uncommented. All running well.

Kind Regards
Edward

Good evening Thank you for taking the time to view my message. Please can you answer the below if possible? A) Can i turn on the firewall on CentOS 8? Will it break anything? $ sudo systemctl start firewalld $ sudo systemctl enable firewalld B) Can i secure the password files? $ sudo chattr +i /etc/...

Thank you Shawn for accepting my post

Good morning My name is Edward. I did alot of research and found eFA and have already implemented it in my lab, fully operational. It does wonders. I have done testing with attachments and double extensions like .exe.pdf and it blocks it 100%. I have already started setting it up for my client due t...
