Thank you steve! This is very help for entry level begginers to under all the email protocol basics. Will keep digging up your other related videos too!
SMTP server can be configured to send email directly to the destination server and they can also be configured to forward to a known server. How they are configured will depend on the policies on the ISP and those that they interconnect with. Organisations running virus scanning will tend to have all incoming email sent to a email server with virus scanning software installed. The main problem you might encounter connecting directly with the destination server is being rejected due to security policies. Rgds steve
Thank you! You may have just helped me get a new job! This helps me start with the basics and it explained reallly clearly. Great job Steve, thank you again :)
Understood everything...except the difference between a desktop clent vs Web based client...Is desktop client means a person using his Gmail through personal PC or laptop. Web based client is a corporate employees who access through Outlook or Lotus- IBM
The email server uses DNS to locate the mail server responsible for that domain. Specifically it uses MX (Mail Exchange records).This tutorial has an example of using nslookup to check MX recordswww.steves-internet-guide.com/using-nslookup/and here is a WIKI explanationen.wikipedia.org/wiki/MX_recordRgdsSteve
Is it like a copy of the mail being sent to the desktop client from the email server? So that if i delete it from the desktop client i can always have a backup in my email server. Could you please clarify? Regards, Swarnadeep Nandy
Hang on... The internet has many different email servers and many billions of emails floating around. How does an email know exactly which email server to go to? I'm assuming the receivers email server (and all email servers) must have an address of some sort, what type of address is it?
Yes correct. All email servers have an IP address. The IP address is resolved using DNS just like any other IP address. All Mail server have additional DNS record entries called MX records. See www.oeupdates.com/beginners-guide-to-mx-records/
Anybody can comment please. My darling sends an email 930am from a time zone that’s 9 hrs ahead and my email doesn’t receive till about 1 minute later which approx 131am. Cool stuff. But the thing is it didn’t load into my actual address till 428am. I found out the time stamps btw by “viewing the original” option by clicking three dots in the particular message I was viewing.
Diagram was more for illustration and not definitive. I take your point that SMTP servers can send mail directly to the destination SMTP server but it does also depend on how they are configured as they can also use forwarders.
