SOLVED New user -> no welcome mail sent to this new user
something strange on our cloudron: when i create a new user and checkbox "send welcome message to this user" is cheched : no mail is sent ! (1)
then if i come back to user and clic on "reset password and invite link" mail is sent ... so is there a bug ? (2)
Note: i don't have any log for (1) in mail.log, do i have to check in other cloudron logs ?
here is the "bug", there is 6 administrators on my cloudron and new user send too many mails for embedded smtp server
2020-12-21T07:32:02.196Z box:mailer BoxError: Invalid greeting from server: 421 Too many concurrent connections: 421 Too many concurrent connections at /home/yellowtent/box/src/mailer.js:86:40 at transporter.send.args (/home/yellowtent/box/node_modules/nodemailer/lib/mailer/index.js:226:21) at SMTPConnection.<anonymous> (/home/yellowtent/box/node_modules/nodemailer-smtp-transport/lib/smtp-transport.js:105:20) at Object.onceWrapper (events.js:286:20) at SMTPConnection.emit (events.js:198:13) at SMTPConnection._onError (/home/yellowtent/box/node_modules/smtp-connection/lib/smtp-connection.js:518:10) at SMTPConnection._actionGreeting (/home/yellowtent/box/node_modules/smtp-connection/lib/smtp-connection.js:893:14) at SMTPConnection._processResponse (/home/yellowtent/box/node_modules/smtp-connection/lib/smtp-connection.js:669:16) at SMTPConnection._onData (/home/yellowtent/box/node_modules/smtp-connection/lib/smtp-connection.js:493:10) at Socket.emit (events.js:198:13)
So @girish or @nebulon is there a solution to disable "new user mail notifications" to some administrators ? or to send invitation mail link to new user BEFORE administrators notifications ? or maybe add a little delay to mail send queue ?
Too many concurrent connections
Oh, that's not too good. Let me look into it. You can comment out this 1 line for now - https://git.cloudron.io/cloudron/box/-/blob/master/src/notifications.js#L120
The file in the server is
systemctl restart box
// mailer.userAdded(admin.email, user);
I will probably remove the email notifications altogether. They aren't exactly very useful since we raise a notification anyway and mostly just a carry over from our very old managed hosting code.
@girish perfect, it works !
