Jul 04, 2017 If you switch to a Mac after becoming familiar with Windows, you'll quickly find that the standard Ctrl+Alt+Delete shortcut doesn't do anything. Mac OS X does have its own version of the Task Manager, but it's a bit different than Windows', and you access it by pressing Command+Option+Esc. Secure Remove Files & Directories from Mac OS X with the Command Line says: June 11, 2013 at 10:50 am from an internal boot disk to an external drive of any type, you would be much better served using the secure format tools for an entire drive that are bundled within Disk Utility, which provide the option of 35-pass secure formatting.

You dont need a Server version, postfix run at no server version of Mac OS X as well.
Has anyone posted a tutorial on how to get all of this working in the non-server Panther? And how to deal with a router (Netgear 314)? There is http://www.roadstead.com/weblog/Tutorials/PostfixEnabler.html, but it does it all for you and hard to tell what has been done and where. Confusing when one is making other changes such as web serving and php which may change some of the same files.

A 'catchall' account is considered harmful by many mailadmins. You should think carefully before doing this, and probably research the topic on some web sites. Holey moley (wcb) mac os. In addition to violating the RFCs, it's not helpful to the people trying to send you mail.

How is it 'not helpful' to people trying to send you mail?
in the same way that Verisign's wildcard domain resolution is not helpful. It doesn't bounce properly. In this case, it (generally) relies on human re-routing.
Like I said, search the web before you implement this. There are plenty of screeds out there from people who feel more strongly about it than I do.
Even if you decide to implement a catch-all, it's worthwhile to know that some people consider it a harmful mail administration technique. You can't make an informed decision about it unless you know that there are reasons not to do so.
How to make a slot machine hit jackpot. I find it an EXTREMELY useful feature; although I've not moved over to PostFix yet, I'm running EIMS, and have it set to forward messages sent to unknown users to my normal account.
What this allows me to do is hand out address willy-nilly to all those Internet commerce sites that require an email address. I use 'site.name@my.domain' (for example, amazon.com@my_domain.com) as the address they require. I still get the mail, and if they've lied about their privacy policy, and I start getting spam to that address, I know *EXACTLY* whose fault it is. Pixelles junk astronaut mac os. At that point, I explicitly disable that account, and the spam bounces appropriately, and that company loses what could have been a very loyal customer.
I agree w/ mcroft on this. If anyone chooses to use this catchall email go for it, it's your domain and mailserver. Choice is what makes the 'Net great. I find it to be a PITA though.
Not only does it breed inaccuracy, like mentioned above, but it also allows more spam in. Since the domain will accept mail to @domain.com, spam will definately increase. Compare the amount of messages rejected for 'User unknown' w/ and w/out the catchall.
I have tried this by following your instructions, but I am not familiar with Terminal Window and Unix commands. I have logged in as root and typed the first line of your instruction followed bt 'Enter.' I then get a long file explaining the PostFix configuration..???I can't seem to follow your explanantion step by step.
Your assistance would be really appreciated as this looks like a helpful hint.

Unfortunately, it looks like your hint requires manual editing each time I add a user. Since I do that a *lot* (hosting a high school), that's not really practical for me.
The postfix help files imply that I can set up a 'luser_relay' address to make a catch-all account, but it doesn't work. I've started a new thread on the topic. Suggestions welcome!
I make no claims to the efficacy or security of this setup. It's working for me.
Add to main.cf: luser_relay=CATCHALL@DOMAIN.COM

The local_recipient_map is empty.
Add to /etc/postfix/aliases: devnull: /dev/null Add 'KNOWNSPAMMERS' addresses as they get discovered and annoy. Be aware that email to these addresses will receive no bounce messages.

the luser_relay may be a deprecated feature. https://ircomdescargargratisfree-bethoodsintragaperras.peatix.com. I am unsure. However, this does certainly seem more elegant than my solution. I am going to try it. Clarevoyance mac os.
