Furthermore, though the general consumer may consider cybersecurity synonymous with the term “antivirus,” the more accurate designation should be “anti-malware,” a catch-all term that describes all malicious software, regardless of type. This is a bit of a throwback to my article from May of last year – Tri-Booting a Mac Pro 2,1 – not long before I had just procured my Mac Pro 5,1 (well technically a 4,1 that was flashed to a 5,1 with dual Intel Xeon 5680 CPUs with 12 cores at 3.33 GHz). How macOS Protects Your Computer. Your Mac has many built-in security features to keep it safe. The bedrock of macOS (formerly Mac OS X) is a rock-solid Unix foundation. This is the same operating system on which BSD and Linux were built, and it’s earned its reputation for reliability and security thanks to a robust permissions system. Essentially, it’s a catch-all category for files on the Mac that are simply not categorized as something specific like Apps, Documents, TV, etc. For the most part, these files are created and saved by various apps on the Mac, mainly in the /Library folder. If you have a spork in hand when you need to cut through a prime piece of steak, you won’t be able to make much progress. Lunchtime picnicking metaphors aside, be aware that a Mac-specific IT support program will always be better than a catch-all system that can’t fully support the devices on your network.

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. 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.

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. 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 <anything>@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 was able to get 'luser_relay' to work for my 'one user' email domain. This allowed me to set up a catch-all without virtual_alias_maps. This also offered the ability to add known spammer email targets (like 'nospam') to a blacklist. Mail to the blacklisted addresses go to /dev/null.

I make no claims to the efficacy or security of this setup. It's working for me.

Catch-all Mac Os Update

Add to main.cf:
luser_relay=CATCHALL@DOMAIN.COM
local_recipient_maps =
The local_recipient_map is empty.

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

As root:
newaliases
postfix reload


the luser_relay may be a deprecated feature. I am unsure. However, this does certainly seem more elegant than my solution. I am going to try it.
