following...

Subject: [cobalt-developers] Sendmail not reject email addresses


I know this is more toward the users list than this one, but I would
rather not sign up for another list, just for one question.

I had a user who subscribed to every mailing list under the sun. The
users account no longer exists, and unfortunately my catch all is still
picking up emails for them.

I tried to add the email address, senders IP, and what ever I could
think of to get my XTR to reject email sent to those addresses.

Absolutely nothing works. I have tons of rules, but mail still comes
through. I thought the catch all might have something to do with the
server not reject email so I made sure to map the old email addresses to
an active account.

Nothing works, and I really do not want to get rid of my catch all,
since I do not have problems with anything except two specific email
addresses. I would prefer to just reject email to those two addresses
but I can't get it to work.

Now in my rules I have even tried using different upper case and lower
case combinations, since sometimes the sender uses all caps, all lower
case, or lower case before the @ and then upper case.

The only thing I have not done is recreate a user account, map the email
addresses to that account, and then suspend the account.

That is the last thing I can think of.

Now I would think this to be more of a sendmail problem than Cobalt, but
certain features of email on my XTR have been broken since the day it
arrived. I would to an os restore, but since the problem existed out of
the box, that will most likely bring me back to the same point.

When making changes to my email account I always get unable to build
email hash error? What ever that means?

Although it does seem that the changes take place in the sendmail files.

Also my server has never accurately reported the uptime or downtime of
the sendmail process. For example if I restart the server now,
sendmail's uptime will not be reset. Instead it usually thinks sendmail
has been up through out the reboot?

It's pretty frustrating because at this point the main reason for our
Cobalt is it's email administration features. We are about to move just
about everything except email to separate dedicated machines.

I was hoping to do this later than sooner, but if I can't get my XTR's
emailing feature under control. Then I will be forced to set up a
dedicated email server using sendmail or possible procmail so I can make
this problem go away.

For the record here are some examples of my rules and for clarity I am
using my actual config, not fake aliases.

I swapped out the cobalt 550 line for the word REJECT but both end up
with the same result. Go ahead send a bs email to that address and it
will go through.

You can also see the one mailing list I am having the biggest problem
with. They send an average of three to five emails per hour.

It's driving my nuts.

I am getting ready to get crazy with ipchains, and our firewalls, but I
will still have to do that for each mailing list. So if I can get
sendmail to reject those two email addresses I will be a happy campier.

Please help, suggestion, comments, and thoughts are all welcome. Please
reserve any insults until the next time you are standing in front of a
mirror.
