Creating thumbnails from first page of a pdf

Using imagemagick - convert:

convert "document.pdf[0]" -thumbnail 150x150 "firstpageofpdf.png"

Since convert uses gs (ghostscript) to process the pdf, remember that gs also needs to be in the php PATH. And of course, that the apache www-user has the correct folder permissions.

Amavisd Spamassassin status header on all messages

Remember, the recipient domain has to be in local_domain_maps in amavisd.conf for the status header to appear.

Example:
@local_domains_maps = ( [ ".$mydomain", ".domain.no", "domain.no" ] );

MySQL backup

mysqldump --all-databases --quick --single-transaction -u backup -p| gzip > mybackup.sql.gz

Change backup with user of your choice and type password at prompt. Or create a localhost-only backup user with read-all privileges.

amavisd-release

To release a file from quarantine, use the amavisd-release program. I could not find this on my ubuntu machine where I installed amavisd-new with apt-get. So I copied the amavisd-release program from the original amavis package and put it in /usr/sbin/

Then I added to the 50-user file: (The newest ubuntu uses a conf.d/ for the amavisd-new settings files. Most others distros use amavisd.conf

$interface_policy{'SOCK'} = 'AM.PDP';
$policy_bank{'AM.PDP'} = {protocol=>'AM.PDP'};
$unix_socketname='/var/amavis/amavisd.sock';

I restarted amavis, and typed the following:

amavisd-release mail_id secret_id

and it WORKED!

I use mysql for quarantine storage, but this should work with regular file quarantine too.

Amazing.
