Blocking a specific to address in mappings
Hi,
I am trying to blocking sending access to a specific address on our front end mta using the mappings file.
The mappings file seems to work if I block on an entire domain, but a specific email address does not work. For example:
SEND_ACCESS
tcp_*|*|*|[email protected] $NMail$ Blocked <--does not block the email
BUT
SEND_ACCESS
tcp_*|*|*|*@ourdomain.com $NMail$ Blocked <---works and blocks all email to the ourdomain.com domain.
Can I not go as fine as a specific email address?
Yes, you can go as far as a specific address, but you have to put in what the MTA is seeing at that point.
Note that imsimta test -rewrite will check your address-based _ACCESS
mapping tables and is quick and convenient to use. But to make really
effective use of this, you need to use all relevant switches (so that the
input makes sense) and enable enough debugging in the output so that you
can see what the probe turned out to be. If you have trouble figuring out
how to use all the test -rewrite switches appropriately to get a meaningful
test, then you will need to resort instead to enabling slave_debug on the
relevant incoming tcp_* channels (as well as, say, MM_DEBUG=3 in option.dat).
For imsimsimta test -rewrite, a starting point might be:
imsimta test -rewrite -from=[email protected] -debug=level=3 [email protected]
But depending upon your configuration, you might also need to use switches
such as -source_channel, -sender, -check_expansions, etc.

How do I block a specific IP address?
How do I block my iMac from looking at a specific IP address? I can't find the answer to this anywhere...
My iMac is connected to the net via a NETGEAR ADSL router and if I look at the NETGEAR settings using Safari to interigate the NETGEAR unit, I can only set parameters for site blocking by using certain keywords. I want to block access to a specific IP address and NETGEAR doesn't have the capabilities of doing this.
Any suggestions?
Cheers!

You could either manually modify your hosts file or you could use the shareware program Hostal if you're not comfortable using Terminal.

How block a specific email address
I have someone who is sending me email and I just want to block their address in MAil. I go to PREFERENCES>ADVANCED....but then I get confused. I get the part where it asks me to type in the text/name I want to block.
It's the "perform following actions" I don't get. I want this person's email blocked but I ALSO want them to KNOW it's been blocked. Like when I get those bounced-back emails from "DAEMON" telling me that it couldn't deliver an email I sent. Which option do I pick? there's one choice that says "Redirect to......" but WHERE do I redirect it? davidHello David.
Nothing is available to do so under the Advanced tab for the account preferences.
You can't block messages from being received/downloaded from the account's incoming mail server that is sent from a designated email address with an email client client such as the Mail.app but you can set up a Rule in Mail to automatically delete all messages received/downloaded that are sent from a designated email address.
There is no Rule criteria available with Mail to automatically "Bounce" a message received from a designated email address and then delete the received message. There isn't a Rule criteria available to automatically "Bounce" a received message either.
Using the Redirect feature is not applicable here and is not what Redirect is intended for.
If you want to Bounce a received message, you must receive/download it first and with the message selected in the message list, at the menu bar go to Message and select Bounce.
The following was copied from Mail Help:
To discourage someone from sending you email, you can reject, or "bounce" messages from that person, as long as the return address is valid. When you bounce a message, it appears to the sender that your address is invalid. This is useful for rejecting mass mailings from companies whose mailing lists you've been added to after buying products from them.
To bounce unwanted messages:
Select one or more unwanted messages.
Choose Message > Bounce.
The senders receive a reply indicating that your email address is not valid and that the messages could not be delivered. The messages are moved to your Trash folder.
Many unsolicited ("spam") messages do not have valid return addresses, and cannot be bounced back to the original sender. If you try to bounce a message that has an invalid return address, it is returned to you as undeliverable.
You can create a rule that automatically deletes mail from a specific sender. Or, use the junk mail filter to remove messages that are likely to be junk mail. -
How to Block Specific IP Address (YouTube)
This is a follow-up question to one I posted earlier this week. I want to block YouTube (and a handful of other sites) from my stepson's new iMac and it was suggested I try/use Leopard's "Parental Control" feature.
I tried that, but the problem is, when he attempts to visit the site, a warning page pops up informing him Parental Controls have blocked the site, then gives him the option to log in as the administrator or to email the admin for access...and that's pretty much the worst thing that could happen. He has serious Obsessive Compulsive Disorder (OCD) and it HUGELY upsets him that he can't guess the Admin password.
Soooooo...can anyone suggest an alternative means of blocking a specific IP address that does so WITHOUT serving up a "Contact the Administrator" message? Someone has suggested blocking the IP address via the network router, but I haven't a clue how to do that.
Any help?
Thanks.Something else you might look at to see if it is suitable for you is to use the DNS servers from www.opendns.com (on your router for example) and set up an account on there, then exclude the sites you don't want accessed - either by the names of the sites OR by the category of site they are.
What that does is NOT actually "blocking the site" as such, what it does is when the workstation wants to resolve the hostname into an IP address, OpenDNS will fail the request. The user will see a browser page from OpenDNS saying that the site was blocked by the network administrator - you can change the wording and even add an icon if you like.
If the user doesn't have admin access to the workstation (whereby they could change the DNS server locally to your ISP's normal DNS, which presumably doesn't offer this sort of lookup-filtering) and they don't know the IP address(es) of the sites they want to access - obviously if the workstation doesn't have to go to a DNS to look the address up, it doesn't matter whether the DNS is blocking the lookup for you - this works well.
There's more information on www.opendns.com - as I said maybe it won't be appropriate for you, but if it is, it's pretty easy to set up and to administer. -

Block a specific address via WiFi (and allow via Ethernet)?
Does anyone know of a way to block incoming connections from a specific IP address ONLY when using WiFi, but allow incoming connections from the same IP address when using ethernet?
Basically, like a micro-firewall. I've found myself in a situation dealing with a bug in our backup software (Retrospect—a once excellent Mac backup solution, now complete junkware that I wouldn't suggest touching with a 10-foot-pole) where it's trying to back up clients when they're on WiFi and the backups fail because it can't sustain the minimum speed threshold set.
There are two bugs I'm dealing with. 1) Retrospect Server is supposed to be IP-specific on the client side, but a bug is causing it to ignore the IP and just see "clients"; 2) Retrospect Server is supposed to "retry" backups again 30 minutes after a failture, but another bug is resulting in Retrospect not seeing the threshold failsures as a valid failure and thus doesn't attempt the retry. As a result, I'm having to manually monitor our mobile devices and manually push backups requests to them throughout the day. Very annoying, and a complete waste of time.
So, if I can find a way, on the client side, to block incoming pings from the server when on WiFi, but allow pings from the same IP when on ethernet, it'll solve my problem.
Ideally, I can do this command-line, without any third-party installations (so the users themselves don't notice anything, so I can push out through ARD, etc.).
Thanks,
Kristin.Hi Brian,
Thank you for your question.
From error, the issue was occurred by sender instead of yours, we could contact Exchange administrator of sender to solve it.
We suggest if there are any restriction on this specific mailbox address.
If there are any questions regarding this issue, please be free to let me know.
Best Regard,
Jim

Outbound emails from one specific email address blocked by Exchange 2013
Hi
We have a hybrid environment Exchange Online and are using Exchange 2013 as hybrid server. We have an application that submits emails to Exchange using SMTP and sends emails from [email protected] Since almost half of our user base is already in Exchange
Online, many of these emails which are generated on-premises need to be routed to Exchange Online. This configuration has been working for months. On 24/06/2014, the emails from this application stopped getting delivered.
On examination of message tracking logs, I found SMTP FAIL events - excerpt below.
ConnectorId : Outbound to Office 365
Source : SMTP
EventId : FAIL
InternalMessageId : 39560943768623
RecipientStatus : {[{LRT=};{LED=550 5.1.8 Access denied, bad outbound sender};{FQDN=};{IP=}]}
Doing a search for the error in recipient status did not return anything but doing a search for "access denied, bad sender" did return results that suggested a scenario when a user in Exchange Online would be prevented from sending outbound email
after having been identified as sending spam - see http://technet.microsoft.com/en-GB/library/dn458545(v=exchg.150).aspx
It seems our on-premises Exchange 2013 server has enacted a similar block on our noreply address which sends out a lot of emails. I have been able to confirm that if the 'from address' is changed to something like [email protected], all emails from
the application get delivered successfully.
I now need to find out how I can unblock our noreply address so these emails can be sent with the original from address.
Appreciate all help I can get on this one.Hi,
From your description, only one email address can't send messages from the application server. I recommend you check if there is any transport rule on Office 365 blocking this problematic email address.
What's more, please check your outbound spam policy, verify if there is any policy blocking this problematic email address.
For more information, here is a thread for your reference.
Configure the outbound spam policy

How do I block specific email addresses?
I am receiving spam that is offensive and unwanted. I want to block the sender's address.
Firefox doesn't do email, it's strictly a web browser.
If you are using Firefox to access your mail, you are using "web-mail". You need to seek support from your service provider or a forum for that service.
If your problem is with Mozilla Thunderbird, let us know and we can move this thread to the Thunderbird queue. This question currently is in the Firefox queue for answers. -
I installed Mountain Lion so that I could sync my notes with my iPhone that already syncs notes with a specific email address I use for school, but during the install it automatically set up Notes to sync w the wrong email addy. It looked in Mail, which had 5 email accounts set up in it, and for some reason picked the only one that I no longer use because it is for a school that I no longer attend. How can I fix it so that it syncs with the correct email account for notes and calendar? There don't seem to be any settings available other than to check if you want to use the basic features. It also said during the set up that it was setting up 'find my mac' but if I look on the iCloud website there is nothing showing there for finding my mac.
At this point I feel like I wasted my money paying for this supposed upgrade. I got nothing for it but frustration. It even automatically set my security settings to allow only downloads from the Mac store so the first time I went to download something I had to stop what I was doing and go correct settings first. I feel like there should be a security setting to block downloads from the Mac store so I don't accidentally end up clicking the wrong thing and being charged.iCloud isn't syncing them on your phone. You simply added the email account to your phone and enabled calendar and notes syncing with the email provider, and the calendar and notes appear in the calendar and notes apps on your phone. You can do this with Gmail, Yahoo and other IMAP account. iCloud email is just another IMAP account, but syncs notes with Apple's iCloud server just as Gmail syncs notes and calendars with Google's server.
iCloud didnt' set up a non-iCloud account on your Mac. When you check Mail in System Preferences>iCloud, it only creates an iCloud email account. You can also add other email accounts to your Mac by going to System Preferences>Mail,Contacts,Calendars and clicking on the "+" sign on the bottom of the left sidebar. If you added these other email accounts to your Mac before you upgraded to Mountain Lion, these were simply maintained on your Mac after you upgraded. -

Blocking an unwanted email address
does anyone know if you can specifically block someone's email address so they know you have blocked them? I realize that the "bounce" allows you to, but I would like to do it permanently, or at least until I choose otherwise. Thanks.
MKurpier:
Although Apple Mail does not allow you to block senders, you can log into your ISP's webmail account and you can often do it there. That is actually the portal for incoming mail. However, it can be an exercise in frustration, as they often change their address sufficiently to get by the blocking software. But if you make a point of doing it regularly you are able to eliminate a few over time. I have one email address where this is a constant problem, while other addresses with the same provider get no junkmail at all. I may just end up changing that email address.

How can I block an e-mail address from sending me spam on my iPhone 5s? My ISP is unable to help. I can block on my laptop via Outlook, but they still come through on my iPhone 5s. Thank you very much.
You can "Move to Junk" and it should start doing it automatically after a few times:

My Airport Extreme is working with an Airport Express to wirelessly extend my wireless network. Both Airports are configured in Bridge Mode per the instructions I found on Apple's support site. I want to assign a specific DHCP address to a wireless camera that is in range of the Extreme, but I understand that the Extreme needs to be in DHCP Only mode to do this. But if I change the mode to DHCP Only, the Extreme will lose contact with the Express. How can I get both functions to work - wireless network extension and specific DHCP addresses?
Then what device is providing DHCP? Only once device per subnet should be the DHCP server. One should be DHCP and NAT and the other in Bridge mode for most home setups. The unit with DHCP and NAT should be the one connected to your cable or DSL and the other set in Bridge mode only extends your network.
On the wireless config page set whichever you're using to extend your network to "Extend a wireless network" and give it the details of the network to which you're attaching it.
