Configure POP3 mail collector.

January 28, 2014, 5:09 am

Hi.

I need to configure a POP3 mail connector in Exchange 2013 to download email from a catch all mail acount at our ISP.

For technical reasons and because of reliability issues with our internet connection we can't put our exchange server directly on the internet and we need to make use of a POP3 global catch all mailbox and SMTP forwarder configuration.

Can somebody please explain to me how I can configure this in Exchange 2013?

I got the SMTP forwarder sorted out but the POP3 connector just does not work.

Can I set this POP3 connector up in Exchange 2013 or do I have to use a third party connector like with Exchange 2010?

Hello

I am having the same issue as the user here:

http://social.technet.microsoft.com/Forums/en-US/3c1e874a-e18a-4b01-ad5e-477acc266ebc/exchange-2013-everything-works-except-outgoing-emails-to-gmail?forum=exchangesvrsecuremessaging

Same error message... I can send to every mail server around the world except for gmail I get the following error:

Remote Server at gmail.com (2a00:1450:4001:c02::13) returned '400 4.4.7 Message delayed'
28.01.2014 12:42:14 - Remote Server at gmail.com (2a00:1450:4001:c02::13) returned '441 4.4.1 Error encountered while communicating with primary target IP address: "Failed to connect.

The last endpoint attempted was 2a00:1450:4001:c02::13:25'

What can be the reason?

OWA being used as a spam / phishing platform, how to prevent this

This past Tuesday after hours, my company was the victim of an OWA exploit that caused our domain to get blacklisted due to sending out millions of spams. I was at a  loss to explain how that could occur, I had traced down the user source and through message tracking logs and IIS logs, and proxy logs, determined the source was a specific user and OWA.

This website describes the exploit exactly. To a T. http://blog.spiderlabs.com/2013/09/hey-can-i-use-your-server-for-spamming.html

The user's account was compromised through a phishing email (which got through the spam filter), and the user was dumb enough to fill out the form.

But that being said, the mechanism the hacker/spammer used to do automated spam via OWA by scripting uploading email to the users drafts and sent items, I would like to hope that MS is looking at patching that so there is no possibility of an exploit. I was fully patched with Exchange 2007 SP3 with the latest Update Rollup (12).

This was a huge black eye on us.

Ways to renew an expiring Exchange 2013 certificate

January 27, 2014, 12:44 am

We have several Exchange 2013 Mailbox servers with certificates which are going to expire in a month. Those certificates were generated by our domain certification authority (it's Windows Server 2012-based). The classic way to renew those certificate is to open EMC, generate a renewal request, send it to the CA, etc.

However, I can open MMC and add the Certificated snap-in connecting it to the local computer store. Can I just right-click the certificate and select All tasks -> Renew certificate with new key ? Or All tasks -> Advanced operations -> Renew this certificate with the same key ? Or can I fulfill the same task using IIS certificate renewal tools?

Those certificates were automatically generated basing using the CA standard Computer template before Exchange services were installed, so they will be renewed automatically. However, Exchange services won't use the renewed certificates automatically, I'll have to assign them manually anyway. I'm just curious if I can speed up the process without waiting for the automatic renewal.

By the way, what would happen if Mailbox server certificates have expired?

Exchange 2007 - Messages with attachments greater than ~500KB are not being delivered to some mail servers - 421 4.4.2

Messages send fine with attachments to most email servers.  But we are running into an issue with some messages that do not send if there is a larger ~500KB attachment.  I can send a large file to gmail for instance 5MB and it goes fine but if I send to a recipient on AOL with an attachment of 500KB the connection to the server drops or times out.
I can then send a smaller attachment to the same recipient and message sends successfully.

 Here is the SMTP Send Log:

Hi all,

Don't know if this is possible at all - We currently running exchange 2010, and would like to hold all mail for new starters for 2 days whilst they are going through training, as they can become distracted.  Then to be released on the second/third day. Any ideas?

Exchange 2013 with multi domains Delivery problems

January 29, 2014, 3:39 am

Hello,

We have Exchange Server 2013 installed as VM in our Windows Datacenter 2008 R2, we have problems in sending and receiving, we are troubleshooting the Exchange to figure out what are the problems, the strange thing is when we configure the Primary DNS and the secondary DNS to 108.178.62.234 (Our Provider DNS) 108.178.62.210 (Our Provider DNS) 50% of emails recipient didn't receive to our Excahge server same as while the sending emails.

Additional Information:

  • We have 2 Static IP Addresses connected to Exchange server (108.178.58.100,108.178.58.120).
  • We are using multi domains to sending emails all Domains SPF records txt value (v="v=spf1 a mx -all" ) we tried to set SPF records to (v=spf1 include:_spf.google.com ~all) but the errors below still received after sending them from Exhcnage server.
  • We configured the Exchange 2013 IIS redirect to https://excas1.wolfsol.com, so all domains redirected from http to https (e.g. http://mail.abc.com redirect to https://excas1.wolfsol.com/owa) and SSL certificate is working fine.
  • We are using one SSL certificate for exchange server issued to excas1.wolfsol.com
  • We set Network Primary DNS to 108.178.62.234 (our server hosting provider DNS)
  • We are not using FOP (because the configuration from Microsoft is not clear for multi domains exhcnage 2013) is there any alternative solution for blocking the Spams. We are receiving hundreds of Spams Emails daily.

Here are some of the errors:

Message Relaying 2013

Hi,

I am new to Exchange 2013 and have read many posts regarding this topic, but I'm still a little confused! So any help or advise would be greatly appreciated.

Basically, we have a current email system (hosted by Rackspace), and have also installed Exchange 2013 on our own server.

Both email system are using the same domain name - lets says 'mydomain.com'

I would like to migrate users (one by one) over to our exchange server. However, I would like to setup a relay so if a user doesn't exist on our own Exchange server, the message will then be relayed to Rackspace.

I have setup our Exchange server as an internal relay, which relays a message sent to a mailbox that doesn't exist back out to our MX records (which currently point to Rackspace) - This works well at the moment, but I'm assuming wont when we change our MX records to point to our exchange server.

How do I go about relaying messages to a specific MX record - say mx1.emailsrvr.com?

Hope this makes sense and thanks in advance for any help.

Dynamic DL expands to no members at Hub

Server is actually Exchange 2007 SP3

I have a DDL (one of about 150) and a couple related Hub Transport rules that cc a handful of other individuals when this particular DDL is in the To or CC fields.

If I preview the membership in either EMC or EMS I see the proper list of members.

If I email the DDL it expands to no members (according to Message Tracking Event ID EXPAND) - no errors as far as I can tell, but no members.  Message Tracking shows two result:  RECEIVE and EXPAND.  After that it just disappears and the related Hub Transport rules are not processed.

If I email the DDL and cc myself it will still expand to no members but the Hub Transport rules kick in and those people are cc'd on the message.  In other words, the people cc'd via Hub Transport rule get the message but the actual members of the DDL still do not.

Any ideas out there on what might be causing this?

We are in the process to migrate our current Exchange 2007 to Exchange 2013.

Our environment is as follows:

HT01= Hub CAS Server (Exchange 2007)

MB1, MB2 = Mailbox CCR Cluster (Exchange 2007)

CAS1= CAS Server (Exchange 2013)

MBNew1, MBNew2 = Mailbox Servers (Exchange 2013)

Emails for users that are on Exchange 2007 can send and receive external emails. But they cannot send emails to users that are on Exchange 2013.

Users on Exchange 2013 can send/receive externally, send to Exchange 2007 users, but cannot receive emails from Exchange 2007 Users.

Linux mailserver to Exchange 2013 migration

Hi all

I have a specific question that I am hoping to get some advice on.

I have successfully installed Exchange 2013 and I am able to send email out from it.

We have a set-up whereby we have a webserver than the mx record for our domain points to, based on the incoming email (based on recipient address) it then will either forward on the mail to a linux mail server or the new Exchange server I have built.

Basically we have a problem whereby email sent from an Exchange mailbox to an internal user that does not have a mailbox is bouncing. I know why this is happening but not quite sure how to fix it. Basically I need a rule or send connector (this is what I am not sure on) that will forward the internal email on to our linux mailserver if the mailbox is not located on the Exchange server I have built (there are reasons we will not be migrating all mailboxes so we need this functionality).

Any help greatly appreciated.

Thanks in advance!
