I am using Swiftmailer in Yii2 advanced and everything, this includes sending emails, works fine on my xampp server. But when I try it on my external Server (1&1 btw) I get a
Swift_TransportException Connection could not be established with host smtp.1und1.de [Connection timed out #110]
I already googled about it for hours an tried almost every solution including using gmail instead or using ports 465 and 25 with ssl and tls. Also using IP-Adress instead of hostname.
I feel like there could be a firewall or some email options I miss but I have tried everything I can think of.
My code looks like this:
'mailer' => [
'class' => 'yii\swiftmailer\Mailer',
'viewPath' => '@common/mail',
'useFileTransport' => false,
'transport' => [
'class' => 'Swift_SmtpTransport',
'host' => 'smtp.1und1.de',
'username' => 'mymail@myadress.de',
'password' => 'mypassword',
'port' => '587',
'encryption' => 'tls',
],
],
and again, works perfectly fine on localhost. Maybe someone has an idea what I am doing wrong?
