That's open source software, there's no one to get ahold of. The way
that you trigger the rule you mentioned is by having an HTML link in
your email which shows in it's text to point to one domain, but in
reality points to another. To avoid triggering it myself, I'll show you
what I mean here:
https://paste.mxroute.app/?3c0c6331e456a71d#3yo1hu5hQximbkGdH3nz2bf1sHtrPZqsCaFGRNE81byL
The way this is parsed, the user thinks they're going to
"whereimtellingyouimsendingyou.com" but I'm actually sending them to
"whereimreallysendingyou.com" instead. It isn't uncommon for this to be
triggered without malicious intent, often because the email uses
tracking links that send a user to a different domain which logs the
click and then forwards them to the domain they were told they were
being sent to anyway.
There are only two ways to solve this:
1. Don't send emails with links like that.
2. Ask the administrator of the recipient server to change
configurations as necessary.

Hi all,
Hope you are well. Does anyone here works or know how to contact
ClamAVNet? I have opened several tickets through their website but I
am not getting any response.
I have a financial institution sending emails and receiving the
following bounce on some B2B domains: _550 Message contained unsafe
content (Heuristics.Phishing.Email.SpoofedDomai_n). After a lot of
digging, I managed to get in touch with one of the B2B ISPs who told
me the reason why emails were failing was due to ClamAVNet filtering
system and I should get in touch with them.
I have managed to find that “Herustics” refers that they are
coming from a financial institution and ‘SpoofedDomain’ means that
they contain hyperlinks that are not known to be associated with the
organization and may be phishing attempt. I can’t find any
suspicious links on the email content.
If anyone know how to get in touch with ClamAVNet, it would be highly
appreciated.
Thanks,
Carlota
