Good afternoon
Faced a problem with sending messages to other users with attached files.
The limit on the size of the attachment has been increased (up to 100 MB). Files can be added.
But when sending, such a message appears.
I checked these files on gmail and he calmly sends them with their original sizes.
What to do?

Re: Sending a message larger

the screenshot clearly says that the limit for message on dest server is about 35MB.
stop sending huge files through mail, it was not designed to work so. implement something like nextcloud and send them links

Thanks for the advice!
The problem is that before the transition, gmail sent files of this weight to this addressee

Who cares what was before? Now it says there is a limit. You can ask admins if they set any limits to mail attachment size.

Re: Sending a message larger

OK. What solution can you recommend? Use nextcloud?

Re: Sending a message larger

for large files you can use google disk, MS onedrive. you can install your own nextcloud. there are lots of options. i prefer my own nextcloud for such attachments.

Re: Sending a message larger

Let's say your attachment is 50MB, after you insert / attach it to an email, the email will be (base64)  encoded and its size increases about 30%, so the final email becomes ~= 65MB.

You should do this simple math while setting message size.

Can you suggest links to instructions for collaboration between nextcloud and iRedMail?

Re: Sending a message larger

there is no collaboration. nextcloud is standalone server, where you upload your files, and then can share them with links
