- In this video i have described how to configure mail server smtps port 465 with sasl and tls. for outgoing email we used to configure email clients with 25 port, but most of the isp blocks outgoing 25 port from the client network for spam protection, because spam bots targets mail servers 25 port from the trusted network. so we need to configure mail clients with smtps 465 or smtp 587 port, so that clients can send mail securely, smtp 465 port ties with SASL authentication and TLS encryption for authentication and encryption from the clients network. I have installed SASL and TLS with Postfix and configure Outlook with 465 port and tested the scenario successfully, after watching the video, you will be able to configure the Postfix SMTPS Port 465 and with SASL Authentication and TLS encryption.

Trying to follow this procedure to set this up from an Ubuntu VM in Azure, but can't seem to make it work. Would be great if you would make an updated video how to do this.
I will try my best, thanks.
How to achieve configuration to make occur error "503 5.5.4 send AUTH command first" or "530-5.7.0 Authentication Required."?
When MUA to MTA connection/Interaction then submission/ssl connection types stuff is happened but how can I configure my MTA to another MTA connection's configuration means will it be 25 port or TLS (587) or SSL (465) port.. Can I block that no other email server can send me email to my email server using 25 port, it has to be 587 or 465 port..
MTA to MTA 25 port by default. if you want you have to configure both server to send receive by different port, smtp protocol by default will connect to 25 port.
When I am trying to send email from my email server to gmail (Google) using telnet on 25 port for smtp transaction purpose it is saying to do STARTTLS (530 5.7.0 Must issue a STARTTLS command first. a27sm3128210pgn.62 - gsmtp
) after mail from: command.... I think MTA to MTA does not require TLS .. Am I right ?
When you use telnet, it becomes a mail client, it is using a non privilege port to connect to gmail's 25 port, when a client is connecting to gmail's server port it is asking for TLS Session if possible. you can configure a mail server with private ip, and can send mail to gmail server, it wont ask for TLS. Thanks
@@mailserverguru Thank you very much...
@@mailserverguru So both Sending Email Server and Receiving Email Server use port 25 at the same time ? Basically sending Email Server can use random port number as source Port but receiving as destination and smtp service provider will use 25 port as destination port.... Is it true or both are using 25 Port when both are doing send/receive to each other ?
Hi, i am facing an issue, i have setup postfix server and mailutils, my postfix master.cf is at gist.github.com/vishal1132/e4d02cc3baf70801676bae06ef1293cf, lsof -i:443 returns something while lsof -i:25 returns nothing, which means the postfix is running on port 465 and not on 25, but when i use mailutils to send the mail, it is still using port 25 to send emails, which is blocked. So i cannot send any email, please help with this.
