randomly fails with some emails about attachment-downloader

[virusbcn]

Sorry, I don't know if more data is needed, if it has not been possible to look at it or if the project is simply abandoned, I would like to ask for some kind of answer please.

The error in the logs suggests the download folder doesn't exist, or there are permission issues that mean that the script can't write to it

I did note you use the argument --output d:\Factu2 but the logs show d:\\Fact u2\\. Not sure where the additional space is coming from?

I wrote this script years ago to solve a problem I had at the time. I no longer have an ongoing need for this, so I can't justify spending my time on issues that aren't easy to reporduce. I do however welcome pull requests from anyone who wants to submit features or bug fixes

First of all thank you and thank you, thank you for answering and thank you for this script and merry christmas.

From James to James, the d:\factu2 folder exists and has the permissions, the bug is random, there are emails that it processes and moves attachments to this folder and others that it does not. The script works under Windows, in the paths that I can control I do not use any strange characters (spaces, ! , ñ, etc.. ) but in the mails that come in and attachments I can not control this, I suspect that the failure comes from there, but I do not know what I can do in the script so that it does not fail in these mails.

I copy and paste the output of the script that I am running now, in the last week it has processed 60 mails correctly and 60 I have had to set aside because it could not process it, it gave error, curiously setting aside these mails to another folder the system works again, it is as if some of them "stuck" it.

I will give you an output of the error that occurs with these 60 emails that I have set aside because it does not process them, I can not see anything abnormal.

Output with several e-mails, including one that does get processed.

Maybe Windows, python and paths are not welcome ???

thank you

I think this part of the log is quite telling:

2021-12-22 12:22:33,425 - INFO - Processing message 'b'30285'' subject 'C/ DE VI

2021-12-22 12:22:33,427 - INFO - Downloading attachment '' to path d:\facturas\

What attachments does that email have? What are they called? For some reason it looks like the imbox library isn't able to pull back the filename?

sorry James, I didn't see your answer (my name is Jaime too, James in Spanish).

Well yes, it seems to have something to do with the name of the attachments, mysteriously some get through and others don't.

Right now I have a lot of stopped emails again, in the end what I have to do is to remove emails until it "hooks" and downloads them, but I can't find any relation other than that the attachments come with spaces, strange characters, etc... but some go through and others don't... ¿??

I don't know if I can or you can send me a private to talk to you.
