Hi,

spamc has no such restriction.  All that needs to be done is increase the
size of the field in the MySQL database.  We use it here with great success.

Regards,

Rick

I'm not too eager checking out the CVS version :-)
I think I have a similar problem with SA as Chris encountered. SA/spamd is
too user-centric. Instead it should be able to take any token and check in
the mysql database if there is a "name" like this. I don't know if spamd
would accept usernames like "user@domain" but I assume it does not. If I
remember correctly the sql schema for the database allows only for 8
characters which is even somewhat scarce for "real" usernames.

This problem does not occur if you use procmail or similar to feed the
messages to spamassassin because these mailers are only launched when
sendmail has already figured out to which user to send to, so there's a
homedir and "real" username. I'm currently checking out a solution with
MailCorral/SA which looks quite promissing. MailCorral solves the problem of
false positives quite neatly by "quarantining" all spam messages. It works
as a sendmail milter, checks the mail for certain malicious content and then
hands it over to spamd and waits for the response, possibly very similar to
spamc. Currently it only hands over the username part of the recipient (or
maybe it's spamd stripping the domain, I can't determine this, I just see a
spamd message in the logs like "processing message <...> for
username:spamd-userid", no message from the milter what it actually handed
over). So, basically this means that *all* mail going thru the system is
scanned and if messages to a@domain1, b@domain1 and c@domain1 all go to user
d there's currently no way for SA to determine a user configuration. If it
would get (which possibly won't be a problem for the MailCorral programmer
if not already done so) and handle a fully qualified email address and use
this for config lookup this would be much better. As an option which can be
disabled in the local.cf, of course. Now, having configs for a lot of email
addresses may be somewhat cumbersome to manage for the users, so I think an
additional option to user per domain config settings instead of per user or
per email address would be quite handy, especially for ISPs/Webhosting
providers.

Is there something like that in the CVS or intended to implement in the near
future? (Bad moment to ask now with the recent irritations about the
NAI/Deersoft deal, I know.)
