Whitelist for domain names (send and receive)

We have this constant issue where our mail server gets loaded up with emails to and from domains that our in no way connected with ours.
Our external firewall prevents these from going out, but they still remain in the Mail Queue. Is there any way to make a white list so that our domain names need to be included in either the sender OR the receiver and then just delete any other SMTP attempts?
Thanks!
Bonus Question. Is there a program I can install on the server that can tell me what IP addresses are sending those emails?

You're potentially running an open relay, and (if that's the case) you'll want to address that.
The open relay can arise via misconfigured mail server, or via a web vulnerability in some web services thing (content management system, etc) you're running.
It's also possible that the server is correctly configured, and that there's an infected client box operating behind your mail server within your domain, or that's external but authorized to use your mail server.
And the unauthorized variation: being a breached password.
You'll want to secure the mail server first and foremost; filtering the outbound domain in the messages won't be particularly reliable, as these folks will just send from your domain and leave you to a: get your mail server blacklisted and b: deal with the backscatter.

Hi Support,
I have Install Exchange server 2013 and create mail box and local send received locally but days back i have not able to mail send and received. what setting are required for user mail send and received locally. and how to create mx and txt record for my
domain.

Hi,
According to your description, I know that the Exchange server can send/receive internally at beginning, however doesn’t work now. Please correct me if there is anything misunderstand.
Great checklist from S.Nithyanandham. Additionally, how about sending/receiving via OWA? And any error messages when can’t send and receive?
Please make sure the Message Tracking has been enabled and run following command to output track log and check detail information:
Get-MessageTrackingLog |FL > "c:\Track Search.txt"
For more information about Message Tracking logs, please refer to below article:

If you want to communicate externally, you need to contact ISP to register DNS MX record.

Unable to send and receive email for external domain

Hi,
I just installed Exchange Server on my 2K8 domain controller. I have set up the send connector and made necessary changes to the receive connector as well. I have updated the DNS records as well on my domain registrar. I can access OWA from outside my companies
network and is able to send and receive emails for my domain but unable to send or receive emails to any other domain. I have checked the delivery report and it says that the message has been queued on the server.
I also did nslookup. Results mentioned below:
C:\Users\Administrator>nslookup www.google.com
Server: localhost

Hi hg01,
According to your description, I notice that you installed Exchange server on a DC.
It is not recommended to install Exchange server on a DC. I suggest install Exchange server on a member server. More details to see:
Installing Exchange on a domain controller is not recommended
http://technet.microsoft.com/en-us/library/ms.exch.setupreadiness.warninginstallexchangerolesondomaincontroller(v=exchg.150).aspx
About your issue, cannot send and receive externally, I suggest make sure the DNS can be resolved first.
Then, check whether Outlook Anywhere has been enabled. If not, please enable it on both Exchange server and Outlook client side.
Last, try to configure both Send Connector and Receive Connector.
More detailed error message will be helpful for the further troubleshooting.
Thanks

Code to retrive the sender and receiver interface names using custome adapter module

Hello Team,
I want to develop an custom adapter module which could retrieve the names of the sender and receiver interfaces of the scenario and for that i am trying to use com.sap.aii.af.service.administration.api.monitoring.ProcessContextFactory.ParamSet but i don't know whether this API will support or not and also i don't know how to develop the code using this API so please suggest me some code for it so that i could retrieve the names.
Thanks you all in advance.
Regards,
Avinash.

Hi,
Just ASMA setting will do the needful. Are you planning to rename your target file name. If yes then only you will require UDF.
Update: Since your directory name will be taken from source file name then you have to use mapping for this, else it will not be possible.
I don't know if creating a new module for this will help you solve the issue, but in that case rather creating adapter module, mapping will be easier.
Regards,
Sarvesh

I have recently bought a new domain which is hosted so that I can send and receive e-mails

I have recently bought a new domain which is hosted so that I can send and receive e-mails & run a webpage. It has POP3 and SMTP settings that I can use to send and receive my e-mails via Outlook on my PC. However, it doesn't work on my iPad. I have changed port settings and appear to be able to send but each time I start the Mail application my iPad reports "username or password incorrect" even though these correctly work on my PC. MS Outlook Exchange 2010 Live Mail works OK with the same settings on my iPad but I would like to get all my mail via the iPad inbuilt application.
Can anyone help?

POP3 accounts are really designed only to be used from one computer and some email providers actually 'lock' the account while in use to stop it being used by another computer/device at the same time.
Try closing Outlook, wait some minutes then try accessing it from the iPad. You may find it works once the POP3 connection has been released.
Ideally, you should be using IMAP because POP3 is old and not suitable for modern, multi-device usage.

How do setup multiple send and receive domain on single virtual ironport?

HI all
how do i setup multiple send and receive domain on single virtual ironport?

Please use the admin guide to assist you for setup/configuration:
http://www.cisco.com/c/dam/en/us/td/docs/security/esa/esa8-0/user_guide/ESA_8-0-1_User_Guide.pdf
On the VESA - the Recipient Access Table (RAT) will control which domains your appliance accepts for.
AsyncOS uses a Recipient Access Table (RAT) for each public listener to manage accept and reject actions for recipient addresses. Recipent addresses include these:
•Domains
•Email addresses
•Groups of email addresses
This is covered in detail in the "Overview of Accepting or Rejecting Connections Based on the Recipient’s Address" section.
Please see the "Configuring the Gateway to Receive Email" section for configuration of appliance for domains.
Please see the "Defining Which Hosts Are Allowed to Connect Using the Host Access Table (HAT)" section for configuration of appliance for sending.
I hope this helps!

TS2755 I have 3 phones on one Icloud account. It has been this way for over a year with no issues. After and update on of the lines started getting text messages from all 3 phones. We fixed the send and receive and it was fixed. It is doing it again.

I have 3 phones on one Icloud account. They have been this way for over a year. After an update last week one of the phones started getting messages for all of the other lines. We fixed this under the send and receive under settings. It was fine for a few days. Suddenly it started happening again. Yesterday after two hours on the phone I changed my apple id and it is still happening. Before that Verizon had told me to turn off my imessage when that happened I could not get any texts at all from other Iphone users.

Make 3 different iCloud accounts and use ONLY for iMessage. That will permanently fix your issue.

MS Outlook 2011 for Mac will no longer automatically send and receive email since upgrade to OS 10.9 Mavericks. Does anyone know of a solution?

I have been having trouble with Outlook 2011 for Mac since updating to OS 10.9 Marvericks. I have tried updating the database and identity. I can get email if a go to each account and try to download it. But email will not come automatically and can I send and receive all accounts. Does anyone have a solution? I do not want to lose my email, contacts and information.

I am also finding that searching in Mail for emails in this account is leading to false negative results. It's astonishing that I can search for an email I know is in the Inbox list yet not find it unless I scroll down to it manually and clicking it. Then it will show up in the results if I search again. I just did "rebuild" a day ago (have to do that every few days or so to get Outlook Exchange emails restored again anyway), so I doubt that this would fix the issue, but even if it did it's ridiculous... do I really have to abandon Mail and move to Microsoft Outlook on my mac to read my emails? Mail is currently FAILING to work for those of us who have to deal with Microsoft servers... which must be a huge # of customers, Apple.

Prerequisites for Sender and Receiver FTP adapter

Hi Experts,
I am new to PI and configuring simple file to file scenario. I need to know the prerequsites for sender and receiver FTP adapter. Scenario is System A -> XI -> System B .
What I want to know is:
1> What ports need to be opened?
2> Any service that I need to activate?
3> Do I need to install FTP server in any of the machine?
If I have missed something, please add.
Br,
Nilz

Hi,
1> What ports need to be opened?
mentioned in below link as said its 21.
2> Any service that I need to activate?
No
3> Do I need to install FTP server in any of the machine?
THere are two ways by which u can pick ur file.
1) NFS by which u can put the file on XI appplication directory and pick up ur file.
2) FTP u have to put ur file on FYP server and XI will pick up the file from there. U can use freeware FTP and install it on ur Desktop search on goolge u will get ti FTP installtion.
refer the below configuration requirement for FIle adapter.

TS4268 Hello, it's been 5 days now since my imessage has not working..and i have chatted to the costumer for two times. I took thier advice and instructions just to enable to send and receive on it but unfortunately until now its still NOT working. Pls.he

Hello, it's been 5 days now since my imessage has not working..and i have chatted to the costumer for two times. I took thier advice and instructions just to enable to send and receive on it but unfortunately until now its still NOT working. Is there anybody who could help me please?

Try this even if you have already. Just make sure to follow the steps specifically.
Go to settings > Facetime > send and recieve > tap on your apple id and sign out. If your not signed in then that will work as well.
Go to settings > Messages > sent and recieve > tap on your apple id and sign out.
Restart the iPad by doing the slide to power off setup. Just hold the power button on the top right till it turns off.
After the iPad has been restarted:
Go to settings > Facetime > and sign in
Go to settings > Messages > and sign in
Wait about 3 min then restart the iPad again. Same instructions as above.
When you restart you should be able to use messages again. If not then call support again and talk to someone higher than the first level support they have.

IMessage waiting for activation. Phone number not listed in Send and Receive at?

I'm going to try to be as descriptive as possible, as I'm not too sure what else I can possibly do to resolve this issue.
3 or 4 days ago I requested a number change through my provider. Not knowing that I had to turn off iMessage whilst waiting for the change to occur, I left it on.
Later that day my friends were complaining that I was sending them texts from two different numbers, one being my new number, one being my old number. The thing is, I'm using the exact same SIM card and it's a little unusual to have two numbers for one SIM. I then realised that iMessage is ONLY registering my iTunes e-mail address and OLD phone number as an option to 'Send and Receive at'. I have spoken to Optus (my provider in Aust.) and Apple, I have gone into an Apple store, had the phone replaced, restored newtwork settings, restored phone altogether, turned on/off iMessage and Facetime, checked date and time, made sure my correct number is listed in Settings > Phone, etc etc etc I've done EVERYTHING listed in all forums that I've read from people experiencing this same issue.
I can choose to select my old phone number in iMessage, and can then send messages to others using iMessage from the old number, and if I switch it off, I'm then using SMS to send messages, and it's from my new number again! It's very frustrating not having all features on my phone working correctly.
If I switch iMessages and Facetime on, not using my Apple ID to sign in, it simply says 'waiting for activation' and after a few hours, tells me it was unsucessful and to try again. I'm all out of options now, Optus don't know what to do, Apple don't know what to do and I don't know what else to do! It's been 4 days! Someone please help!?

Just thought I'd let everybody know how it finally got resolved 1 week later!
After trying absolutely everything, and I mean EVERYTHING that Apple support, apple forums etc told me to do, the only thing that worked was turning iMessage off, waiting for at least 24 hours at then turning iMessage back on.
It activated itself within a few minutes, no dramas at all!
Hope this helps!

My phone number is not coming up as an option for sending and receiving imessages

My phone number is not coming up as an option for sending and receiving imessages

You do not have a "phone number". Your ipad has a cellular access number and can't make phone calls.
You must use your apple ID email for imessage and FaceTime on iPad.

Programmable infrared (IrDA) sender and receiver for iPhone

Hello,
I want to communicate with the iPhone and a device which only supports infrared for communication, so I'm searching for a programmable infrared IrDA sender and receiver for the iPhone. It should be possible to communicate with the recommended communication protocol from Apple or with any I implemented by myself.

Nevermind, I deleted the contact in iMessage (OSX) and the messages are now being delivered in gray.
