Ok, here's how I see how the .clean thing works (not in exactly this order, but . . .)

When you get an email destined for the domain that you set up for Anomy, a .clean is appended to the address, and the sanitizer is used as the delivery agent.

Anomy gets and cleans the message, and returns it to sendmail to be delivered to the .clean address.  Sendmail then uses the second rule to strip the .clean, and deliver it locally (or wherever it should go).

Since .clean is not a TLD (and is normally non-deliverable), this is a simple and elegant method to separate messages that have and have not been sanitized.

On my (working) system, if a message is sent to a non-existant user, then I get the same type of bounce that you described below (with the .clean).

Tha! t's because with the sanitizer, every message you get is really two messages.

First its received, and delivered to the sanitizer, and then its re-sent by the Sanitizer, and relayed through localhost, to the recipient.

The first message was destined for the actual email address, but WAS delivered to the sanitizer, which accepted it, so it did not bounce.  The message sent by the sanitizer was then sent to the .clean address.  Now, sendmail should have a rule to strip the .clean for delivery, but if the user does not exist (or maybe that rule), then the bounce gets the original destination address in it (with the .clean).

 

Now, if the destination address really does exist (i.e. its deliverable, without the .clean), then you have another problem.

 

Is it possible there is a typo in the rules you put into! sendmail.cf

Take a look at the lines:
R$* < @ $+ .CLEAN. > $* $1<@$2.>$3
R$* < @ $+ .CLEAN > $*  $1<@$2.>$3

 

You should probably have both, and there needs to be a tab character between the "$*", and the "$1".  Spaces will not do.

No, you don't want to label the .clean as a local domain.  The rule:
R$* < @ $=w . > $*      $#sanitize $@anomy $:$1<@$2.CLEAN.>$3

already kinda does that, by sending mail destined to the $w domains to the "sanitize" delivery agent.

BTW, you can change this line if you like, to sanitize mail to domains destined to a separate variable from $w.

I do this on one mail server, which has several local domains, and also acts as a relay ! for some other domains of mine.  I want those relayed domains sanitized as well, so I created an anomy variable, which has $w in it, as well as the other domains I want to sanitize.

Subject: Re: [anomy-list]: Installation WAS Re: Commercial Support

Hello Bjarni and you all.

Thank you very much for the reply. Ill check out the FProt package. Wow..
f-prot remembers my my BBS years. Os/2, Remote Acces, pascal coding, he! he...
great times :]

I have installed Anomy in a server for testing, and faced an problem. When I
send a message to someone in the sanitized domain, it gets back to me with
550 Host Unknown. Just like:

- I send email to carlos@dominio.com.br
- I receive a messa saying that carlos@dominio.com.br.clean does not exist

I see that the .clean is added in one of those rules  that I do not fully
understant (those that were put in sendmail.cf). Maybe im missing something,
like telling sendmail that dominio.com.br.clean is a local dom! ain that
should be forwarded to dominio.com.br? Or something else?

I appreciate your support. Thank you.
