Re: "Path to message" vs filename length issue
IIRC File name and path length hare independent. Most operating systems have a limit of 255 characters for the filename. On linux, the maximum path length is defined by PATH_MAX which is in most cases set to 4096. I am not sure why it crashes when I set the regex value to 255, but I assume the regis...

Re: "Path to message" vs filename length issue
Thanks for the info. It looks like changing the value to 240 did help. The service did not like it when I set it to 250 though. I do still want to have control over extremely long files, so I keep it at deny for a while. We'll see how it behaves. This will resolve my issue, but does not fix the bug ...

"Path to message" vs filename length issue
We have a problem where email is blocked with "Bad content" (Blocked File: Y) because of the filename length. While the filename itself isn't long, the "Path to message" is much longer. i.e. "New document.doc" vs "20250128/45gtsmw4hFzqgP/New document.doc" How ...

Avoiding "Very long filenames" blocking
Many e-mails are blocked as "Bad content" only because: "MailScanner: Very long filenames are good signs of attacks against Microsoft e-mail packages" This happens even though the sender is on a white list and so are the file extensions. I have looked around but haven't found a c...

Re: filename.xml.pdf - Allowlisted, Bad content
Ok, I found the "issue". The sequence of rules is important. The general rule for double extensions MUST be last in the sequence of rules. # Deny all other double file extensions. This catches any hidden filenames. deny \.[a-z][a-z0-9]{2,3}\s*\.[a-z0-9]{3}$ Found possible filename hiding A...

Re: filename.xml.pdf - Allowlisted, Bad content
I've run the --lint test which found couple other entries with syntax errors that I fixed. (yeah, there were still spaces instead of tabs) They are now fixed and there are no errors reported. Yet, the pdf file I renames to file.xml.pdf is still filtered out: "The following e-mails were found to...

Re: filename.xml.pdf - Allowlisted, Bad content
Ah, apologies! Brain fart! oh no Eyefart or something dumb.
Thanks for your patience. I've re-formated a couple lines that were added over time but the e-mails are still being filtered.
"The following e-mails were found to have: Bad Filename Detected"

Re: filename.xml.pdf - Allowlisted, Bad content
thanks for the reply _M_P,
I copy/pasted one of the original lines so the tab-formatted content was there the whole time.
I just didn't use the </> code formatting here in the forum. (in hinesight, I should have)
And I also did restart the MailScanner.

filename.xml.pdf - Allowlisted, Bad content [SOLVED]
Hi guys, our eFa 4.0.4 with MailScanner v5.5.1 is blocking file attachments with double extension ".xml.pdf" even though I modified the filename.rules.conf to allow it using: allow \.xml\.pdf - - The message details say: Blocked File: Y SPAM Allowlisted: Y Any hints/ideas why that is? Thanks

Re: Increase spam assassin score for gmail
Since I created the rule, there were several updates and restarts of the system. Never the less, I've re-checked all the recent 20 mail from gmail and the rule was applied just fine. I had the problem with the rule not being applied every time only after I created the rule some months ago. So, from ...

Re: Increase spam assassin score for gmail
I added these 2 lines at the end of the /etc/mail/spamassassin/local.cf
It seems to work partially as I don't see the rule being applied every time a mail from gmail.com is received.
Code: Select all
header LOCAL_DEMONSTRATION_FROM From =~ /\@gmail\.com/i
score LOCAL_DEMONSTRATION_FROM 2.0

Do you have eFa behind firewall? Are you using a tunnel through NAT?

Re: Increase spam assassin score for gmail
Hi,
I added the custom rules, but they were not applied.
I found out that I have to run sa-update and sa-compile from /etc/mail/spamassassin/ folder.
Is it enough to run this from the GUI console in webmit or does this need to be run as root? (using sudo)
Are a ny other steps required?
Thanks

Re: EFA is not processing all mail
Hi,
try the same solution as in this thread.
viewtopic.php?f=19&t=4845&p=18134#p18134
It might be a timeout problem.
