Squirrelmail attachments error "Could not move/copy file. File not attached"

If you get this errors in Squirrelmail "Could not move/copy file. File not attached" when trying to attach a file, it is not the php.ini upload_tmp_dir setting, but the attachment.

Check this directory and, if doesn't exist, create it with proper permissions (usually apache's user & group)/
Go to squirrelmail configuration (execute config/conf.pl script) and choose option 4 - Generatl Options:

Code:

SquirrelMail Configuration : Read: config.php (1.4.0)

In the following scree check the 2nd option (Attachment Directory):

Command >>

For me, this directory didn't exist (stupid me).

Code:

# mkdir /var/local/squirrelmail/attach/
# chown nobody.nogroup /var/local/squirrelmail/attach/

Now it works (or it should be). If still there's an error, check that php.ini has uploads enabled (file_uploads = On).
