Re: mimedefang+spamassassin+sendmail

hi again!

has anybody implemented a mail spam gateway using these technologies (sendmail,spamassassin,mimedefang)? honestly, i don't have much experience in setting up mail servers, however the case may soon change since. sendmail alone is monster! thru the years it has evolved and the latest release is ver. 8.14.2 from the sendmail.org site.

the scenario: is this, i have installed sendmail on a SLES10 box and its primary function is to filter out internal emails using the three technologies. looking at the logs proves very daunting...not to mention the configuration details and learning curve requires that you have to had superpowers perse on sendmail alone.  again, searching google prove worthwhile to pointing me at materials that help setup a SLES10box with the three technologies working hand in hand?

however, i used the stock rpms to install sendmail with the exemption of spamassassin and mimedefang which was compiled from source.

my question is this:

1. given the default install and looking at the logs it seems i can send emails to external recipients but not on internal recipients????...anyone from the list who  encounters similar problems?

Not that problem. 

I gave up on sendmail due to load and other reasons also so complicated to do 
the basics. and so easy to break with one mistake.

I moved to 
Postfix  - SMTP
Dovecot - IMAP and POP3
Horde - Web Mail, calendar , notes, todo list, password management
openldap - users - aliases - addressbook
Ldap-Account-manager - manager the LDAP fully
spamassassin - gets 80% junk mail sorted.
amavisd - gets some more junk and banned items
clamantivirus - all viruses removed
sshdfilter to allow access if i need but block if attacked.
I have it set to check for blacklisted IP addresses

It does not allow relay

It also allows some users internal sending of email only and some external and 
internal sending. Some i have set to only send to single domain outside.

That was the best so far, still slowly adding to it to improve performance and 
controls.

Re: mimedefang+spamassassin+sendmail

I had a similar setup in one of our clients, the major differences
though are I'm using mysql for user authentication (virtual domain
setup) and I'm using mailscanner + spamassasin + f-prot for junk
emails and viruses and postfixadmin for account and domain management,
great for a dummy like me :D

French police go open source (Ubuntu)

Oh La La! French Police Go Open Source
Savings could top $10 million a year.

January 31, 2008 | posted by Lee Pender

Despite what you might have heard, nobody in France actually says "Sacre bleu!" as an expression of surprise. Maybe people did at one time, but they don't anymore. These days, "oh la la!" (yes, just like in the old Sassoon commercials) is the expression of choice. So, if you're going to react with shock to the fact that the French national police force has dumped Microsoft for Ubuntu Linux, please, use the proper French expression.

Over the next few years, the gendarmerie -- remember, there's a national police force in France, not a collection of local police entities like what we have in the U.S. -- is going to shift its 70,000 desktops from Windows to Ubuntu, which, incidentally, is far and away the operating system with the name that's most fun to say.
Les flics ("the cops" in French) say that they'll save more than $10 million a year in license fees. And they're already using OpenOffice and Firefox, so there shouldn't be too much of an open source culture shock inside the organization. What we're wondering, then, is whether it's really true -- as Microsoft claims -- that running Windows is actually cheaper than running Linux despite the cost of Windows license fees. Sure, there might be some issues with integration somewhere, and there aren't as many experts trained to service open source applications as there are to service Windows, but still...$10 million a year? Oh la la, that's a lot of money.
We kind of wonder, too, whether, the European Union's regulatory war on Microsoft might be having a ripple effect on government IT departments overseas. (Oh, by the way, the U.S. will keep an eye on Microsoft for another 18 months, too.) We've read that some major European cities have also started to ditch Redmond's wares, and Europeans -- especially those who work in the public sector -- are sometimes more prone to listen to their governments than Americans are. (Actually, that's also true for people who don't work in the public sector. Your editor distinctly remembers reading and hearing during his time in France about how public service announcements about safe driving actually worked over there -- and fairly quickly and impressively, too. Then again, some of them were pretty disturbing.)
In any case, we're not going to jump on the alarmist, Microsoft-is-dying bandwagon that probably has one or two fewer seats today. Remember RCPU's rule: No matter what happens, Microsoft makes more money. But, the more Linux penetrates enterprise and government settings on the desktop, the more Microsoft had better think long and hard about what its partners and customers need Windows to be -- maybe, to start with, lighter, cheaper, more flexible and less like Vista.
Do you run into competition from open source on the desktop? Is running Windows really cheaper than going with Linux in the long run? Let me know at lpender <at> rcpmag.com.

Nabasa kona ang dovecat at Cyrus Mailbox server dito sa plug pero baka meron pa kayong alam na maganda.
 
Thank you.

Based on my experience, one of the easiest mail server (SMTP) to configure is Postfix, Qmail is not that far off. You can combine Dovecot with Postfix and use Postfixadmin to administer your mailbox and domain. It uses MySQL or Postgres as database backend to store user information. You can also setup a complete out of the box SMTP server like Zimbra and OpenExchange, it comes complete with Anti virus and Anti Spam solution. Both are administered via webgui.

Hi Froilan,

na Mailbox Server?

| Nabasa kona ang dovecat at Cyrus Mailbox server dito sa plug pero baka 
meron pa kayong alam na maganda.
The best way maybe is to try these programs yourself and choose the 
"best" according to your liking and criteria.
What is your definition of ease in administration and configuration; are 
you looking for a GUI (ala SWAT) configuration tool?
Are you looking for those extra features (LDAP/SQL support, etc.)
Are you referring to the most sensible and easy to understand debug log 
messages?

Given the two solutions that you have mentioned above (dovecot and 
cyrus), dovecot is much easier to configure and administer imho.
Performance wise, i don't know about how cyrus is performing now since 
it's been ages since i last use cyrus, but dovecot performs very well
either in mbox or maildir mailbox formats thanks to it's small footprint 
and smart indexing.

hth,
Kenneth

Air duster spray can to clean PC

Hi all,

I remember reading a thread here about PC maintenance using a compressor to remove dust.
I'm just wondering, can i use a vacuum cleaner to do it? or if not, where can I buy an Air duster spray?

TIA

We buy cans of air in Home hardware - Ace - True Value.

You can use a Vac  but it is sometimes not strong enough and the Head - Pipe 
is to big in other cases.
