Errors sending and receiving emails

Hey guys,

I have setup a custom email domain on my ERPNext and setup a few email addresses for sending and receiving emails. However, I’m getting these errors in my error logs:

First Error
Error Title: Error

Traceback (most recent call last):
  File "/home/frappe/frappe-bench/apps/frappe/frappe/email/doctype/email_account/", line 732, in append_email_to_sent_folder
    email_server.imap.append("Sent", "\\Seen", imaplib.Time2Internaldate(time.time()), message.encode())
AttributeError: 'bytes' object has no attribute 'encode'

Another Error that I get for every email address that I have created:

Second Error
Error Title: Error while connecting to email account Support

I have tested these email accounts on IMAP outside of ERPNext and they work fine. Anyone knows what’s causing this?

Thank you.

try: bench enable-scheduler , and look at the error logs

HI @smino I installed ERPNext using Docker and is on production. I remember because I during the installation, the docs said I didn’t need bench for ERPNext. Now when I see the commands, I’m afraid it would overwrite my instance altogether. Is there a safe way to do this?

My knowledge of Docker is limited. First and foremost a backup should be made of your image so if something does happen you can revert to an earlier instance. @revant_one may have a suggestion for that. As far as I know Bench is an integral part of ERPNext and familiarization with the commands is essential for successful maintenance. The bench enable-scheduler is not likely to cause any problems.

bench cli is a wrapper that makes from frappe user friendly.

bench cli also does supporting things like nginx and supervisor setup, config setup etc.

In production docker images there is no bench cli installed.

the only bench commands it contains is from frappe’s

Speaking of enable-scheduler, it is part of “framework commands”, it is available in production docker containers.

Run bench --help to know available commands

Hi @smino and @revant_one

Thanks a lot for replying and assisting me on this. I think I forgot to include the most obvious thing that I was getting. When I type any bench command, I get the following:

Command 'bench' not found, but can be installed with:
apt install ruby-active-model-serializers  

Which led me to my answer above. I don’t have bench with my production docker instance which kinda confirms what @revant_one was suggesting. Is it safe to install bench on production machine? And what’s the best method to go about with this?

bench is required in case of non docker install.

bench is not installed in docker containers because with bench ERPNext images size goes up to 3GB+.

If you are using non-docker install, easy_install or manual install, then bench is required.

Hey @revant_one, sorry for being MIA, was in a lockdown with no internet :sob:

So since I’m using docker, what should I do to get the output similar to bench enable-scheduler ?

bench enable-scheduler is available in container
