Smarter message size limit

[anon36435246]

Hi link2xt.

@link2xt

This will not prevent others from using another email client and sending you a large message anyway.

This is not true… maybe… for this reason: - If you want to reduce the size of the email message, consider the 4 alternatives: temporary file service, temporary messaging service, limit the amount of characters in the message, limit the amount of messages in the message group

list of things to avoid large messages

1. temporary file service: some temporary file services limit the amount to 2g as file-io/web-transfer etc or 100mb or 10mb as tempmail etc.
2. temporary messaging service: some temporary messaging services limit the amount of sending messages to 10 messages per day, 100 messages daily as tempmail, temporary-email etc.
3. limit the amount of characters in the message: 255 characters(twitter), 1.500 characters(Discord) etc.
4. limit the amount of messages in the message group: you could check in a group of messages the total amount allowed, for example - gmail allows up to 350 contacts up to 350 messages.

as we can see, there are 4 ways to avoid large messages

Besides that, the problem discussed in OP is not about text messages, but about attachments which are megabytes (millions of characters) in size.

But… temp files site has file size limit, file-io enforces 2gb file limit for upload. file-io-temporary-storage-in-delta-chat - this would be another way to avoid large files. (What I mean is that you would not send a file to the email, but only the temporary download link to be downloaded on your mobile.)

• So… another way would be to… you can also limit the amount of file according to the space stored - I say in the download part.
• So… another way would be to have an delta-chat-api service to check the file size before uploading.
• So… another way… would be… protocols like ipfs, ftp, sftp etc can be used with some file limit. you could set the acceptable amount of file to transfer a file in ipfs/ftp/sftp for example.

As we can see, we have other ways to avoid a large file, either through the use of the delta-chat-api service, or through third-party services that have an acceptable limit on the amount of file or some network protocol that limits the amount of file to be sent.

I think fragmenting the message is the best solution. It is probably not widely supported, but at least there is a standard which Delta Chat can implement to avoid reinventing the wheel:

this idea is interesting, fragmenting the messages… would be possible if these messages are binary.
