Re: Invalid user writing to himself
Posted by Serge Knystautas <se...@lokitech.com>.
Hmmm. that's quite an interesting predicament. Normally if a message
enters a loop like that, you get many received headers created, and mail
servers (including james) will kill the message after a suitably large
number.
In this case, I guess it's NotifySender that's creating the problem. This
is kind of hard to catch, as while it'd be easy to check if the sender and
recipient are the same, it might not be that easy if there is address
forwarding or something else.
Really want we should do is have those notify mailets now send the message
with the 'null' sender (MAIL FROM: <>). This is to create a message that
does not bounce. The code in CVS now supports the null sender, but I don't
think the mailets have been changed to do this (although they will not
notify sender if the sender is null).

I use the following inside the <spoolmanager> element in
config.xml (which was james-config.xml):
<processor name="transport">
<mailet match="RemoteAddrNotInNetwork=<your networks>"
class="ToProcessor">
<processor> spam </processor>
</mailet>
<!-- local filter -->
<mailet match="HostIs=<your domain>"
class="ToProcessor">
<processor>localproc</processor>
</mailet>
<mailet match="All" class="ToProcessor">
<processor>internet</processor>
</mailet>
</processor>
<processor name="localproc">
<!-- local delivery -->
<mailet match="RecipientIsLocal" class="LocalDelivery">
</mailet>
<!-- nice feature; but could lead to a "ping of death" of your
mail server; the choice is yours -->
<mailet match="All" class="NotifySender">
<notice>We're sorry. Your email could not be delivered; no such
user(s).</notice>
</mailet>
</processor>
<processor name="internet">
<mailet match="SenderHostIsNot=<your domain>" class="ToRepository">
<repositoryPath>db://Message2/wrongsender</repositoryPath>
<passThrough>false</passThrough>
</mailet>
<mailet match="All" class="RemoteDelivery">
<!-- the setting is as usual -->
</mailet>
</processor>
Basically, the above setting is to have a "localproc" processor and an
"internet" processor which handle locally destined messages and remote
destined ones. The local processor has the RecipientIsLocal matcher to see
whether the messages are indeed locally destined (make sure that the
elements in <servernames> block (in <James> block) represent the local
domain(s)).
The "internet" processor has a SenderHostIsNot matcher, which sees whether
the sender is not from your domain; meaning, messages that sent via your
James and not from the local domain will be stored in the repository; in
which you could check them out later from which IP numbers the messages
were sent out. This would restrict your James to deliver (out) the
messages that originate from your domain only. The originating IP numbers
(network numbers) have been filtered by the RemoteAddrNotInNetwork
matcher, and the sender domain is by the above matcher. I think, ideally
the matcher should be SenderIsLocal (so it does check whether the users are
from your domain).

Invalid user writing to himself
Posted by Jacques Lema <ja...@link-u.com>.
I have a page on my site (http://maplante.meet-u.com/) that allows (in
order to offer a virtual plant) sending email to another person.
Apparently if both the TO and the FROM user name are invalid
for example: sending from "bob@meeeeeeet-u.com" to "bob@meeeeeeet-u.com "
The mail enter an infinite loop... as it is refused and sent to bob.. who
doesnt exist, who doesnt exist and sends it to bob... and so on?
How should I filter this? (Using James 1.2.1)
