processor question
I'm using James to serve a couple lists using a slightly modified
version of the listserv provided in the James source. Everything works
fine if somebody emails "list-xxxxxx@mailhost.perspectivesoftware.com".
I have a matcher in the root processor that catches "list-xxxxxxx" and
sends it to the listserv mailet. However, if somebody sends to
"list-xxxxxxx@mailhost.perspectivesoftware.com,list-yyyyyyy@mailhost.perspectivesoftware.com"
the mailet only picks up the first list and discards the second address.
Is there a better processor for me to put the matcher where it would
catch the two distinct lists after they are split by James? Or do I
have to rewrite the listserv to be more intelligent about recognizing
that more than one list is involved?
Thanks

So then the set of non-matching recipients picks up at the next mailet?
That may explain my problem. I wrote a matcher called "RecipientIsLike"
which matches any recipient like "list" and sends it to my custom
listserv. The listserv then looks at the original recipient and queries
the database for the list of users. Which means that I only have one
mailet that will match the "list" so that I don't have to modify the
config.xml file everytime my users add a list to the database.
Technically both recipients in the example "list1@perspectivehost.com,
list2@perspectivehost.com" should match. Then the listserv only
processes the first in the list so it never sees the second listserv
address. In your example it would work because you have separate and
distinct mailet/matches for each list.
So my backup plan of looping through all recipients in my listserv
mailet is actually a good solution since it will process all matches,
and any non-matches will continue on through the processor pipe.
Right? I was worried about losing the non-matches but it sounds like
that won't be a problem.
In any case, it doesn't sound like there are any bugs here, just a
misunderstanding of how things work.

Wait a minute ... Jay, I was wrong ... distracted making dinner ... hold on.
The matcher does it. The way a matcher works is that it selects the
recipients that will be processed by the mailet. Matchers like HostIs are
just all or nothing, but otherwise, the matcher says which subset of
recipients will be processed.
So if I have multiple recipients, and use RecipientIs, then only that
recipient should be passed along to the mailet for processing.
So if I have e-mail sent to "list1@perspectivehost.com,
list2@perspectivehost.com", what should happen is that the RecipientIs
matchers should peel off a single recipient for the listserv mailet. The
recipient set will get split into two sets: matching and notMatching. As
long as neither one is empty, it continues. So the matching set, containing
just the current list, should be processed by the listserv. The message is
then ghosted. But the other set still continues with its duplicate of the
message.
So now that I've had my dinner, if you are not seeing the above behavior,
then we need to find out why.
Ignore my earlier message.

OK, I'll add it.
For future reference what is the mechanism in James that would split the
two if the first wasn't a "list-" match? I noticed that if I send to
"somebody@someexternalhost.com,list-xxxxx@mailhost.perspectivesoftware.com"
something causes the second email address for the listserv to be put
back through the processors so that it works as expected. It seems like
if I could put the listserv mailet at a different point in the processor
piping the two addresses would be split into independent messages before
it ever got to the mailet and matcher.
In the meantime I'll probably modify my listserv mailet to loop through
all the recipients and send to them rather than just the first in the list.
Thanks.

Please put that in bugzilla. There isn't a quick fix because the mailet
doesn't know the address that caused it to be invoked.
JDBCListserv supports a <list_address> element, which tells it the address
it supports. That should probably be added to AvalonListserv.
Mark's new list serve has the same bug.

Its a listserv based on the old listserv, I think I modified the
JDBCListServ. I have the mailet in the root processor, matching on
"RecipientIsLike=list-".
The problem is that if somebody sends a comma separated list of
recipients my matcher picks it up as one address and the second address
just gets dropped. I'm guessing that somewhere along the way the comma
separated list should have already been broken up into two "rcpt to:'
entries, but that is out of my control.
In your example below, if somebody sent to
"list-xxxxx@mailhost.perspectivehost.com,list-yyyyy@mailhost.perspectivehost.com"
wouldn't the first matcher catch the email and then ghost it when done
so the second match on "list-yyyyyy" would never happen?

How are you matching? Which mailet? I would have something like:
<mailet match="CommandForListserv=list-xxxxx@mailhost.perspectivehost.com"
class="AvalonListservManager">
<repositoryName>list-xxxxx</repositoryName>
</mailet>
<mailet match="CommandForListserv=list-yyyyy@mailhost.perspectivehost.com"
class="AvalonListservManager">
<repositoryName>list-yyyyy</repositoryName>
</mailet>
<mailet match="RecipientIs=list-xxxxx@mailhost.perspectivehost.com"
class="AvalonListserv">
<repositoryName>list-xxxxx</repositoryName>
</mailet>
<mailet match="RecipientIs=list-yyyyy@mailhost.perspectivehost.com"
class="AvalonListserv">
<repositoryName>list-yyyyy</repositoryName>
</mailet>
That's using the old listserv (current listserv). I haven't switched over
to using Mark's new one, yet.
