Closing this one too because it looks like an internal thing and most developers shouldn't care about this.

That's not internal at all. That's useful when one wants to use more than one mailer in their apps.

Yes ... but the way I understand it is: Symfony defines a name for the built-in transports ... so you see those names for example in the webprofilerbundle. But, when we document #12259, we'll show how you name each mailer ... but that doesn't have any consequence in the app. Each mailer must have a unique name in the app ... but that's it.

So, if we document #12259 ... this issue is no longer needed I think. Meanwhile I'm reopening so others can express their opinions. Thanks!

Thank you for this issue.
There has not been a lot of activity here for a while. Has this been resolved?

Could I get an answer? If I do not hear anything I will assume this issue is resolved or abandoned. Please get back to me <3

Hey,

I didn't hear anything so I'm going to close it. Feel free to comment if this is still relevant, I can always reopen!
