Mail client roundcub attachment upload size is displayed incorrectly

[R.B]

I set the email attachment to 20MB in the management panel, but it shows 100MB in the mail client . How can I solve it? thank!

Yes, there is discrepancy between roundcube and Poste because roundcube takes setting from PHP (max_upload size) which doesn't know how large attachments SMTP accept. I will let this issue open, we might find solution eventually
