In Squirrelmail configuration, I have : upload_max_filesize 10M In Postfix (SMTP server), I have : message_size_limit 10240000 (~10M) Then I can attach a 8M file in a mail but if I send it, the file is encoded and gets bigger (11M). The SMTP server rejects it. Finally the solution is to define a higher message size limit in SMTP server. Thanks for your help.
