@MailerName not working with different SMTP servers

[wansors]

Describe the bug

Quarkus fails to send emails using different SMTP servers when using: @MailerName

The config is readed ok by quarkus, however the problem is that the SMTPConnectionPool returns always the same connection with the same MailConfig. Making all @MailerName to use the same connection.

Expected behavior

Each @MailerName should use its own SMTPConnectionPool. And send the emails using each connection

Actual behavior

Each @MailerName share the same SMTPConnectionPool. And send the emails using only one connection

How to Reproduce?

Use the code on:
https://github.com/wansors/quarkus-multiple-mailers-test

Try sending emails on dev using the endpoints:
http://localhost:8080/smtp/send/1 http://localhost:8080/smtp/send/2

One @MailerName is using an incorrect port, however mails are send anyway because the vertex SMTPConnectionPool returns always the same config
