Can't Bulk Email Books to Kindle

[xxomegan]

Hi everyone! Newbie here. I've searched long and far but haven't found the answer to this. I've been using Calibre (updated to v6.23) for about a year or two. I have multiple books loaded into Calibre. I use the connect/share feature to email my books to my Kindle address and it works fine ONLY if I send one at a time. If I select MORE than one book, only one book will send through. The others will appear in the Jobs list and be working forever and will not send through. I then have to cancel the jobs. Additionally. Once I stop the jobs, and try to send another book separately, it will not work either. The job just loads and loads.

My only solution is to send one book, force quit the app, open the app, and send another book, force quit the app, open the app, send another book and so on and so forth. Is there anything I can do to fix this? I use a Mac, updated to the latest version of Calibre and everything seems fine. My books are always epub files and I have them set to auto convert to mobi before emailing. I'd love to send multiple books at once instead of having to force quit the app in between emailing each book.

Thanks so much!

E-mail is not for Bulk transfers.
Think about what happens. Each book needs to be processed (their policy), then forwarded to the device over a network they pay for.

If you want bulk, use USB (AFAIK, no Kindle allows Bluetooth or FTP transfers)

Mostly true. But they are only paying for processing and storage if you use WiFi. They are only also paying for transfer from Amazon to Kindle if you are using Cell/Mobile built into a Kindle. Many Kindles in use are WiFi only.

Does anybody have problems using GMX.com recently? Since the beginning of this week any attempt to send files via gmx.com ends up with the following email from Amazon:

A message that you sent could not be delivered to one or more of
its recipients. This is a permanent error.

The following address failed:

xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx@kindle.com:
SMTP error from remote server for RCPT TO command,

Using gmx.com reley works I just sent 4 ebooks to my kindle.

Open calibre in debug mode send a ebook to your kindle and post the result--if it works will look like this:

The problem is not with e-mailing files from Calibre (it works flawlessly) but with Amazon blacklisting IPs. I just couldn't figure out if its GMX or my own IP that Amazon doesn't like. If you had no problems with it, I'll try to change my IP by using VPN to see if it solves the problem, and report back when it's done.

There is a problem with Your Calibre i(5.44) nstall

ModuleNotFoundError: No module named 'httplib'

[gbm]

That error has to do with his xray_creator plugin.

  File "calibre_plugins.xray_creator.ui", line 14, in <module>
ModuleNotFoundError: No module named 'httplib'

Plus he has a problem with his apnx_generator plugin.

He needs to disable them or uninstall them.
For further troubleshooting he should send his ebook to amazon as an attachment using his email program.

Sending ebook manually from GMX mailbox ended up with the same rejection reply from Amazon. However changing my IP with VPN solved the problem, hence my ISP is blacklisted by Amazon for some reason. Have no problems with logging in on Amazon.com though, so it only affects send-to-Kindle functionality.

Anyway thanks everyone, with your help I got rid of obsolete and unused plugins.
