Is it possible to make mail autodiscover use port 587 by default?

Modify the autodiscover configuration files /usr/local/psa/admin/htdocs/mailconfig/autodiscover.xml and /usr/local/psa/admin/htdocs/mailconfig/autoconfig.xml and perform it automatically with an event handler after Plesk Update:

1. Log in to Plesk via SSH

2. Create the file /root/autodiscover_587.sh​ with the following content:

   #!/bin/sh
   
   # set port 587 for Plesk autodiscover
   sed -i 's/{{SMTP_PORT}}/587/g' /usr/local/psa/admin/htdocs/mailconfig/autodiscover.xml
   sed -i 's/{{SMTP_PORT}}/587/g' /usr/local/psa/admin/htdocs/mailconfig/autoconfig.xml

3. Make the file created in step 2. executable:

   # chmod 755 /root/autodiscover_587.sh

4. Execute the script one time:

   # sh /root/autodiscover_587.sh

5. Log in to Plesk Interface and navigate to Tools & Settings > Event Manager

6. Create an event handler by clicking Add Event Handler with the following settings:

   

7. Click OK
