hi all i am new here, nice to meet you all :) i have a question regarding migrating exchange server and allow incoming mail from WAN. I have migrate all mails form the old server to a new server using exmerge. now my new server have every mails. the new server has a domain name let say abc.com what i don't understand and unsure is that is map-ing the abc.com to my server static ip and exchange port will allow user outside or from other network to send mail to the exchange server? because let say there is a tom in abc.com so the mailing address is [email protected] so how does the sender mail know where to send to? Thank you.

I will try to break this down for you...

abc.com is a host that you own

dns information:

mail.abc.com is another dns entry that points to your outside ip

there is a mail exchange record within the dns server that contains mail.abc.com that points to mail.abc.com for mail traffic to go to that external address (this is how the world knows to send mail to your mail server)

exchange has an entry saying that it is the host for abc.com to send and receive mail for abc.com. with port 25 being forwarded through your firewall to you mail server, all mail going to abc.com will be received by your mail server. How it receives is by having the correct dns entry on your internet dns server that hosts all internet dns records for abc.com.

Make sense?

Thanks for the reply, i have a clearer picture now. I this case i do not have to concern anything else as i have already map the abc.com domain name to the static IP. Thank you.

      Wow, spoken like a true blind hater, you don't even provide arguments. Please, go check my comment above to @seacaptain and you'll find out why what you say doesn't make sense in this context...

      Get used to this, with AI tooling now uncovering new vulns and getting them exploitable far faster than has ever been possible before software is going to need to be updated far more frequently. Back in the day it may take reseachers weeks or months to do what AI can now do in hours. Once its a threat is discovered it's weaponsized far more quickly, meaning you simply can't be waiting 2, 3, 4 weeks to deploy a patch, it needs to be patched immediately. Going to be interesting handling this in the enterprise space where traditionally patching has been steady, but very staged (and rightly so up until now), that is going to have to change.

      You don't need to "close all browser sessions constantly" or wait for updates to install. The updates download in the background while you use the browser, without interrupting you, they install automatically the next time you launch the app. And they install very fast (depending on your storage speeds, of course), you have to wait at most 2-3 extra seconds, if any. Seems like you haven't used Edge in a loooooooong time...
