i'm using claws mail 3.8.1 for windows upon sending mail with attachment, it usually fails with attachment more than 100kb (xlsx). the message says "could not queue message for sending". i've searched docs and settings to allow larger attachment to no avail. no such settings found. when i send email with small attachment (9kb xlsx), it succeeds.
Probably dup of #2262 *** This bug has been marked as a duplicate of bug 2262 ***
