Symfony version(s) affected

7.3.2

Description

This concerns the sendgrid-mailer component.

When a region is given, it results in the following address: smtp.{region}.sendgrid.net

However, for the global region, it must result in smtp.sendgrid.net (as if no region was given). smtp.global.sendgrid.net does not exist.

How to reproduce

Use the following DSN: sendgrid+smtp://{api_key}@default?region=global

It results in the following error:

Connection could not be established with host ssl://smtp.global.sendgrid.net:465

Possible Solution

Treat the global region differently from other regions.

Of course, the workaround is not to provide a region at all. But not being able to always define a region complicates configuration of the DSN somewhat (when it's assembled from different parts).
