MATLAB sendmail configuration for a SMTP server - matlab

We were using an internal SMTP server and Matlab's sendmail function worked well. However, our SMTP server has changed and instead of smtp.companyname.com, we now have an ip address, say 10.23.154.2.
The new server doesn't require authentication and also no SSL connection. Still, we are not able to send emails
Version - R2013a,
setpref('Internet','E_mail','XYZ')
Old Config: setpref('Internet','SMTP_Server','smtp.xxx.com'),
New Config: setpref('Internet','SMTP_Server','10.23.154.2'),
As per IT team, telnet worked on the server and SMTP worked fine with IronPorts. Please comment.

The IP you're using to send mail is not authorized 550-5.7.1 to send email directly to our servers

I am new to DO and I have tried to look for solution online but I didn't find any answer. I am using Ubuntu OS 20.04(LTS)X64 version.
My question is that I have 2 droplets, MailServer droplet where I have installed docker composer and mailcow to run mail mails, and another droplet named WebServer hosting my domains. I have also set up all required DS records under my domain added on WebServer droplet and pointed A record mail.mydomail.com to the IP of mail server droplet. However, whenever I try sending emails they all bounce back unless the ones sending between mydomain users(user1#mydomain.com & user2#mydomain.com). It just says that "The IP you're using to send mail is not authorized.....".
Any support to help me solve this issue will be highly appreciated. An I am wondering if that approach is possible or if there is any documentation on how someone can set up dns records on one server and configure mailserver on another server using digitalocean.
Here is how I set my DNS on mydomain.com to point to MailServer IP

Query reg SMTP port

Hi am having a confusion reg SMTP ports. I have configured an application in my local machine to use gmail's smtp server by getting the details from here - https://www.siteground.com/kb/google_free_smtp_server/ and am able to trigger emails without any issues.
When I set the same application in a windows server and use the same smtp settings the emails aren't going and I keep getting errors like "unable to connect to smtp port 465". So is the port being mentioned here - 465 - is this port being used from my machine to connect to gmail's smtp server or is this port being referred to the port in the machine where gmail's smtp server is hosted?

Mail sending but not receiving on Plesk server

I am having some PLESK Mail receiving issues.
I just setup a dedicated server with 1and1. The server console is PLESK 12. I am using 1and1 nameserver which are pointed correctly from the domain registrars. I am able to send mail using webmail but not able to receive it.
When I do a mail server check it I get the following error:
Error connecting to mailserver: No route to host
If anyone is aware of some missing SMTP settings that need to be set up in the initial Plesk configuration it would be appreciated.

Grails mail plugin configuration for MS Exchange server

I am able to send email using my gmail account from my grails application but when I use MS exchange server account I am getting this error
Message: Mail server connection failed; nested exception is com.sun.mail.util.MailConnectException: Couldn't connect to host, port: smtp.exg6.exghost.com/, 25; timeout -1;
Configuration I used is :
mail {
host = "smtp.exg6.exghost.com"
port = 25
username = "xxxx"
password = "xxxx"
props = ["mail.smtp.auth":"true",
"mail.smtp.socketFactory.port":"25",
"mail.smtp.socketFactory.class":"javax.net.ssl.SSLSocketFactory",
"mail.smtp.socketFactory.fallback":"false"]
I am not sure what configuration to use. I tried changing port to 465 & 993 but that didn't work too. Please help
There are several things wrong with your setup. First of all, you are submitting mail to a Microsoft Exchange server (presumably), not Outlook. Outlook is a mail client and only provides end user functionality by connecting to the same server that you are trying to get the Mail plugin to connect to.
Your host name must be a valid Internet DNS host name -- therefore it must be "smtp.exg6.exghost.com". This might be all you have to do depending on the submission/relay policies in your SMTP server. Most likely you need to read on.
The SMTP protocol supports authentication and security for mail submission (new message injection) using either SSL or SASL. If you are using SSL, the default port to connect to is 465 (SMTPS port). If you are using SASL, then most servers are configured to accept new mail with authentication on port 587 (submit service port). Most SMTP servers will not accept mail submission on port 25.
In your case it looks like you are trying to connect with SSL, so you probably want to configure it using the SMTPS setup. To make sure that you have a proper setup, use a mail client like Thunderbird to try to make an SMTP connection to the server. It actually has a discovery algorithm in it that will try the common setups and report success when it has found one. Once you know what the connection parameters are, then you can proceed with configuring the Mail plugin.
I finally got this working. Turns out Microsoft provide a separate API / web-services to send email and perform all other mail related operations. This API gives developers programmatic access to Exchange Online, Exchange Online as part of Office 365, and versions of Exchange starting with Exchange Server 2007 Service Pack 1 (SP1). Click here for details.
exg6.exghost.com is host for Exchange Server 2007
And I am not sure but I think Exchange server 2007 and onwards don't use SMTP.

Local SMTP Server

I used IIS5.1 prior with the Virtual SMTP Server to send some internal mail. However, we've been upgraded to IIS7.5 and there is no SMTP Server for some reason Microsoft doesn't have a fit explanation for. Is there a comparable local SMTP Server that I could use (I only need send-only, not a full mail server, if that makes a difference)?
In short, you can still use IIS6 SMTP server on IIS7.5, or you can use a free smtp server alternative as listed below.
IIS6 SMTP:
Is the SMTP virtual server deprecated in IIS 7?
