🐞 bug report

⁉️ Describe the bug

Is there a limit to download an attachment with a mailscanner cron?

as all generated PDF files are larger than 9 MB they simply dont import.

1. Go to Mail
2. Click on Attach a file
   3.Attach PDF file Larger then 5 MB
3. Check the corporate emails record,
4. No attachment

Lately a limit equal to the upload value specified in configuration has been added.

I however think that the reason why your attachments aren't being downloaded is because of something else, namely their verification security-wise. If you check your logs you will probably see entries that confirm that.
The latest servicepack for 5.1 includes a fix that improves file verification. It will most likely eliminate the number of rejected files.
I recommend updating your system to 5.1 + servicepack v4.

@rskrzypczak

I understand. Maybe you know What is the class or file that verify attachments for the mail scanner?

Unfortunately 5.1 was not stable when it just came out. And now i hope it will be 5.2 comming soon, as most of bugs from 5.1 been fixed in it. Also i have integrated couple of modules out of yetiforce production, which make update not as smooth.
Waiting for 5.2

@rskrzypczak
i will test the new version and come back with feedback, i am surer that something wrong with size as the pdf is generated by yetipdf.
And i cannot just disable the security check on codeinjections.

My question would be: it should actually log the error when i enable logging but where would it go? system.log or error.log?
i dont see any errors in there

@rskrzypczak can you open the issue? as it is a bug and it is not fixed!
