Within Internet message handling services (MHS), a message transfer agent or mail transfer agent (MTA) or mail relay is software that transfers electronic mail messages from one computer to another using a client–server application architecture. A MTA implements both the client (sending) and server (receiving) portions of the Simple Mail Transfer Protocol (SMTP). The terms mail server, mail exchanger, and MX host may also refer to a computer performing the MTA function. The Domain Name System (DNS) associates a mail server to a domain with mail exchanger (MX) resource records containing the domain name of a host providing MTA services.

Hello!

I run my own HTTP, SMTP and DNS server on a local box. I have LAMP, Postfix and BIND9 on Ubuntu to be exact. Everything was great, except that the e-mail which was sent from my mail server often got rejected by the remote SMTP servers due to lack of correct rDNS (PTR) record (basically, I never bothered to ask my ISP to update it for me, so it was a generic one). So finally I did it. My ISP updated rDNS record for an IP address that I use for all the servers (they all are together on one physical computer). So an IP resolves to the hostname of my mail server, which is:

mail.mysite.com

When I do reverse DNS lookup with "nslookup" command, by FIRST choosing Google's DNS server (8.8.8.8), then I get the correct hostname. But when I use my own DNS server, I get servfail error. Right now every server of mine seems to be working correctly. I haven't seen anything unusual or some problem with anything. So should I just wait for the DNS propagation (my ISP updated an IP about 6 hrs. ago) OR is there anything I personally should update either in my DNS server's settings or something else maybe?

The environment is Windows 2012 Hyper-V  /  Exchange Server 2013

I have a mail database on a VHDX drive with the database log files located on another separate VHD.

I am currently NOT performing any jobs (Move mailbox .etc..)  however the log files are growing at a rate of 22Gb per hour.

This was not happening during the evening and has only just started when staff arrived at the office and opened Outlook.

How is it possible to find out what is causing the Log files to grow?

All the outlook users have Cache mode enabled.  Is it possible that this is caused by synchronization errors?
Most mailboxes are over 10gb.  Largest mailbox is 19Gb.
There are 28 mailboxes on this database.

I am trying to locate my company mail server address. We just switch over from an on-prem (Exchange 2010) to off-prem now hosted by Microsoft.

I did do an nslookup however I want to make sure this is the correct way to do this.

Also there is a port that is referenced not sure if that is the correct port ??? I am posting this in the Microsoft portion just to make sure I can get the mail server name

I am performing the Exchange 2003 to 2010 migration.  They are currently running in coexistance with some user mailboxes on 2003 and some on 2010.  I am unable to connect to active sync externally from my phone.  I ran Exchange Remote Connectivity Analyzer and get the following result:
Testing TCP port 443 on host myserver.mydomain.com to ensure it's listening and open.
       The specified port is either blocked, not listening, or not producing the expected response.
Anyone know what the problem might be.  It matched matches my external URL on Active Sync.  I have an A Record for the host name to my external Static IP.  I have the Firewall setup to allow the External IP to redirect to my internal IP

Hello,

I have a client that attempted to clean out emails on her MAC for several hours. NOw, as soon as the MAC Synced with our Exchange server all the mail came back that she deleted. What would cause this to happen? How can I prevent for the mail to come back once she syncs to our Exchange. It seems like while she is deleting the mail isn't being updated properly to Exchange.

I have Exchange 2013 and client has standard MAC mail app settings.

Thank you!

Hi there. As the [sole] IT person for a <25 user small business, I am looking for advice on whether to dive into an Office 365 premium subscription, complete with cloud access to office as well as exchange, OR to do office apps only and keep our email domain hosted with a 3rd party.

I feel like our current vendor is going to deliver us news that we must change up our service due to Microsoft's "unplugging" the current shared exchange service (this I heard from a sales person).

We currently pay 12/month per user including complete admin support and management of exchange as well as an anti-spam solution (Symantec).

Microsoft says office 365 premium (incl. Exchange) costs 12.50/per month for 1 yr/user.

I feel like the Office 365 Premium subscription offer doesn't include the same level of administrative support as either 3rd party email host.

I feel like our current vendor is going to soon-deliver us news that we must change up our service due to Microsoft's "unplugging" the current shared exchange service (this I heard from a sales person).

Add to this Comcast business offering office 365 solution for $14.95/month per user.

I would appreciate a few inputs so I might make an informed decision for our company.   Many thanks for your consideration!  :)

I have a site I built (WordPress) for a customer a few years ago. On the contact page, it has a contact email, info@philsirrigation.com. That forwards to somewhere else. The customer want's the forwarding changed to something else.

The site is hosted at GoDaddy. I know the email it is forwarded to, I assumed I could go to the GoDaddy Account & figure that out, wrong, the GoDaddy user interface is a nightmare.

Can someone tell me how to find the email forwarding at GoDaddy?

Thanks

Hi all,

We have 2011 SBS server that was set up to send and receive emails for 2 different domains, let's say domainA.com and domain.com.

OWA access, autodicscover, etc were all defaulted to remote.domainA.com.   The UCC SSL certificate referenced remote.domaina.com and autodiscover,domaina.com and all worked fine, even with access to domainb.com emails (which were accessed remotely by configuring the proxy server details in Outlook manually.

The issue we have now is that domain.com is no longer used and we want everything to reference domain.com instead, also some external users are now running Outlook 2016 which seems to insist autodiscover is correctly configured to connect.

Can someone please talk me through what I need to do in Exchange 2010 to make everything default to domainb.com? I appreciate I'll need to re-key the SSL certificate and will need to create A records for autodiscover.domainb.com and remote.domainb.com but it's the stuff within Exchange I need to know about.

Many thanks for your help!

I setup a new exchange server and can send emails outbound. but I need to setup external DNS. can someone help me with the configuration. I am using Godaddy for our external DSN

I know I need to set the MX but should I set it to the external IP and do I need to set any other records.

And after talking to godaddy I cannot setup the MX record as just the IP. So i'm a little lost at how to setup the MX record.

We will be transferring our domain from oldHost to BlueHost.
oldhost IP is 169.*.*.28, The old mail server has 12 accounts like help@myDomain.com
newHost IP is 108.*.*.57. The new mail server already has the same 12 accounts with the exact same names (e.g. help@myDomain.com)

I want to be sure that we see all email sent to us during the transfer propagation period.

What is the best way to do this?

-------------- here are some more details ---------------------------------------------

oldHost and newHost only host email.  (they offer web hosting but this question is not related to that offering).

12 clients with office 2010 or 2013 running under windows 9 or windows 10. (Not using exchange or anything like that))

Both oldHost and newHost recommend the same Outlook account settings:


incoming email server is mail.mydomain.com on port 110 (no ssl)
Outgoing email server is mail.mydomain.com on port 25 (no encryption)
and so on for Name, User Id, Email Address, password etc.



Let's say that at 6:00 pm Monday I give newHost the EPP unlock code and the "A" record is changed to 108.*.*.57

At 6:01, my friend in china sends an email to rberke@mydomain.com. That email will "accidentally" go to 169.*.*.28 because the IP address will not propagate to China very quickly.

For the next few hours there will be fewer and fewer accidents, and eventually all email will got 108.*.*.57

I have an Exchange Server running on Windows Server 2008 R2. Exchange Version 2010. Total Users are about 30. I just started using backup software, and every time I initiate a backup, it always says "Mailbox Replication Service is not running". I then manually restart the service and Re-Run the backup but still the same result. I also found a patch from Microsoft and when I try to install it, it says installation ended Prematurely.  It is my clients Exchange Server, and we are just maintaining it. I can't re-install the whole Exchange. Did reboot my server multiple times, all the backup progress is stuck in QUEUE at either 0% or 10% but nothing is going on.

I need to setup a server to relay emails to 1500 clients at the end of the month.

Currently the provider that I use for email doesn't allow more than 1000 emails a day. this causes problems with mail flow. I'm trying to setup the IIS based SMTP server on my Windows Server 2012r2 but it's not letting me. I'm having a similar problem as this post, https://serverfault.com/questions/500197/sending-emails-using-iis-6-0-smtp-service-without-using-a-relay, but I don't understand the resolution posted about gTLD. Can someone explain it to me or provide me a better way to accomplish what I need to get done?

Thanks

We are running Exchange 2013 in a hybrid environment O365. A user account was disabled within AD and now that we re-enabled and try to locate Exchange account it doesn't list mail account within deleted or allow me to re-enable? I can see account within Get-remote mailbox, however how do you re-enable or resync it?

Thanks,

The Eight Noble Truths of Backup and Recovery

How can IT departments tackle the challenges of a Big Data world? This white paper provides a roadmap to success and helps companies ensure that all their data is safe and secure, no matter if it resides on-premise with physical or virtual machines or in the cloud.

Dear Experts

While I am aware of email marketing best practices like good list, content, unsubscribe link but would like to understand how the domain reputation becomes one of the important factor for mails deliverable to the inbox.  I understand few email marketing service provider provide dedicated IP's and we can replace, if the IP gets black listed and looses its reputation, when we change the IP , will this not resolve and every time IP reputation goes low replace the IP and move on sending bulk mails, please help me in understanding the below
1.  how does the domain reputation takes control in delivering the messages to inbox because when keep chaining dedicated IP whenever it gets affected if this is the case in what way domain is getting affected would like to understand that the ISP's or Search engines by any chance have tracking system that "so and so domain" has undergone many times IP changes hence domain reputation gets low score and finally with too many times IP changes the  associated domain gets black listed and finally even though the Ip is changed this will not help us to further send email campaigns please suggest
please  support on the above , thanks in advance

I have installed Exchange 2010 onto Server 2008R2. I have an SAN SSL certificate from Godaddy installed on Exchange (mail.domain.com and autodiscover.domain.com). I have a Cisco ASA acting as a firewall and a Sophos XG135 in bridged mode acting as the email filter. Email can be sent and received without a problem and the email is being filtered. OWA works from the outside without a problem, however, Outlook Anywhere will not work. I have poured over the available documentation from Sophos but cannot get a remote Outlook client to connect to the Exchange server using Outlook Anywhere.

Has anyone successfully configured the XG in bridged mode to work with Outlook Anywhere? What steps am I missing? Do I need to install the SSL cert on the XG instead of Exchange and make the XG an SSL Proxy? If so, is there any documentation on how to go about this with the Godaddy certificate?

OK, the subject pretty much says it

Despite running repairs on said mailboxes, several of the mailboxes on our Exchange server keep failing when being exported.

The error message is Too many bad items.

The command I am trying to use to repair the boxes is:
New-MailboxRepairRequest -Mailbox <<MailboxName>> -CorruptionType ProvisionedFolder,SearchFolder,AggregateCounts,Folderview}

Open in new window


Anybody got any helpful ideas?

Thanks in advance!

We have outsourced our email and recently I was asked by  our auditor if I have SPF and DMARC records set up?

How would I know if this was done?

Can someone explain to me what he is asking me-  and with outsourced email should it be done if its has not been completed already?

This email attachment size limit message is driving me crazy, I have revised everything and still haven been able to understand why exchange is restricting the size since I have increased it to 35mb, can someone here help?

"This message wasn't delivered to anyone because it's too large. The limit is 10 MB. This message is 21 MB"
