Can't use Sendmail on a Joomla Stack on AWS

IMPORTANT, please fill the questions

We assume you are using Bitnami to deploy your application.

Which version of the application are you using?:
Bitnami Joomla! 3.9.13-0
My Joomla install is up-to-date.
Please choose how you got the application: Installer (Windows, Linux, macOS), cloud image (AWS, GCE, Azure, ...) or VM (VMDK, VBOX):
I copied the URL from the AWS cloud page on Bitnami and pasted it into the EC2 launch instance interface (didn't get it from the AWS Marketplace).
Have you installed any plugin or modified any configuration file?:
I added Sendmail itself and follow the instructions to enable it in the PHP.ini file.
Describe here your question/suggestion/issue (expected and actual results):
We can no longer use Simple Email Service (SES) because my client has decided to move her mail to Office365. I would like to use Sendmail for her Joomla transactional emails, but I cannot get it to work.
Steps to reproduce the issue (if relevant):
Open Joomla, go to Global Configuration, click on Server. Select Sendmail and click Send Test Email. I get two errors:

Notice: Could not execute: /usr/sbin/sendmail
Error: Test mail could not be sent.

Copy the apache log (if relevant):
n/a

Can you advise how to get Sendmail to work?

Hi @Toolie,

I couldn't reproduce your issue with Sendmail. I installed it in the server running the command below and it was detected without issues by Joomla

sudo apt-get install -y sendmail

Can you check it is properly installed on your server?

sudo which sendmail

Also, I'm afraid I don't know how to configure sendmail for sending emails using Office365. Can you check it in a more generic forum like Stackoverflow or the Joomla official forums?

https://forum.joomla.org/

Apart from that, do you know if using sendmail is strictly necessary on your case? Can you try if configuring Joomla with SMTP instead of sendmail, and setting the Office365 information works for you?

You can get the official SMTP configuration for Office365 from the link below

I had already installed Sendmail successfully and tried to use it to no avail, but thanks for the instructions.

I obtained the SMTP Credentials from my client, and they're still not working to authenticate with Office365.

Can you tell me where the errors for SMTP are logged on the server so that I can at least get an error code? They don't show up in the Apache logs, and I don't know where else to look.

Thanks!

Hi @Toolie,

Maybe setting the Apache LogLevel to debug in the httpd.conf file helps you to get that information, but note it will make the Apache log file bigger very fast, so I recommend you to have it enabled the required time to do a quick test only.

You will need to restart Apache for changes to take effect

sudo /opt/bitnami/ctlscript.sh restart apache

Note the SMTP settings must be different when using Office365 instead of AWS SES, so we recommend you to ask in the official Joomla forums for further help on this.
