Unable to send email from Calibre

[philfr]

Hello,
I can send email from Cloudron admin menu (Email / Domains: Action send test email) with succes.
But I can't send email from Calibre. Once in the queue, it fails...
On the logs, there is the folowing traces:

DEBUG {cps.tasks.mail:194} Start sending e-mail
DEBUG {cps.tasks.mail:62} send: ehlo [172.18.19.85]
DEBUG {cps.tasks.mail:60} send: AUTH PLAIN
DEBUG {cps.tasks.mail:60} send: AUTH LOGIN
DEBUG {cps.tasks.mail:62} send: **********
ERROR {cps.tasks.mail:199} (535, b'5.7.8 Authentication failed')

(Not sure if line 62 is sensitive data, so I've replace it with stars)

The Calibre "email server settings" are the original ones:
SMTP hostname: mail
Port: 2525
Encryption: None

Thanks for your help !

Hello here. I have the same issue. Is there anyone here able to send emails with Calibre-Web?

Works for me Since the original report, we made a fix to the package to fix it. Is your app package up to date? Which version are you running?

My version is Calibre Web 0.6.23 (calibre 7.16.0)

and I'm trying to use SMTP from Fastmail

@chetbaker does sending a test mail work ? https://docs.cloudron.io/email/#send-test-email

[chetbaker]

Yes it does.

But as I said, I'm trying to use Fastmail SMTP because that's how I can send books to Kindle. Maybe I should forget about that and just use the cloudron SMTP?

[joseph]

@chetbaker ok, so you are using Fastmail directly inside Calibre? If it gives auth failed, unfortunately, I have no idea about where it can be wrong. Could be Calibre issue or Fastmail side.

As an aisde, the package has to be adjusted first to even support this across restarts. Without that, don't you lose your Fastmail configuration each time your restart the app? Currently, the app sort of requires you to use Cloudron SMTP .

@joseph this is great, thanks!
