Hi Joseph, thank you for your reply - autoupdates where enabled for plugins. Let me check if that solves the issue :).

Hi there :),

I am getting a "Briefly unavailable for scheduled maintenance.[..]" regularily with the Managed Version. I tried to change that by allocating more ressources, but neither did that help nor seem ressources to be the problem according to the usage.

When checking the log, these requests seem to happen when the error occurs:

Apr 29 08:18:10 Executed the cron event 'wp_version_check' in 11.85s.
Apr 29 08:18:10 Success: Executed a total of 3 cron events.

If someone has just a hint on what I could check next, I would be glad :).

Thank you Joseph - that helped a lot. Then, everything just works fine :).

Hi Joseph,

sorry for being unclear here - the mail is being send out if I set $mail->SMTPSecure = ''; like in the example mail at https://docs.cloudron.io/apps/lamp/#email. However, once setting it to $mail->SMTPSecure = 'tls'; I get the error above.

Will $mail->SMTPSecure = ''; use TLS anyways if the outbound relay is configured to do so?

Hi there,

I am trying to send a mail via SMTP and PHPMailer.
The script works fine unless I try to set SMTPSecure to tls. This causes_

"SMTP Error: Could not connect to SMTP host. STARTTLS command failed Unrecognized command"
587 is set as port and the outbound relay is looking okay.

If someone could point me in a good direction, I would be very thankful :).

Remaining arguments:

$mail = new PHPMailer(true);
$mail->isSMTP();
$mail->Host = getenv('CLOUDRON_MAIL_SMTP_SERVER');
$mail->SMTPAuth = true;
$mail->Username = getenv('CLOUDRON_MAIL_SMTP_USERNAME');
$mail->Password = getenv('CLOUDRON_MAIL_SMTP_PASSWORD');
$mail->SMTPSecure = '';
$mail->Port = getenv('CLOUDRON_MAIL_SMTP_PORT');

$mail->setFrom(getenv('CLOUDRON_MAIL_FROM'), 'Mailer');
$mail->addReplyTo($email, 'Hello back');
$mail->addAddress('dummymail@dummy.com', 'Cloudron Test');
$mail->Subject = 'Hello World';
$mail->Body = json_encode($content, JSON_PRETTY_PRINT | JSON_UNESCAPED_UNICODE);
$mail->CharSet = 'UTF-8';
$mail->Encoding = 'base64';
