The client is setup in full cron. I have the following script, called chg_vacation_msg, which is located in /var/www/clients/client2/web7/autoresponders Code: #!/bin/bash # copy autoresponder msg cp /var/www/clients/client2/web7/autoresponders/test.txt /var/vmail/mailfilters/domainname/testaccount/.vacation.msg If I execute this script under shell, using ./chg_vacation_msg , the file gets copied ok. If I do su web7 and execute the script, the file gets copied ok too. I put the following in the CRON interface in ISPC3 : the log gets created, but is empty, and the file is not copied! syslog contains this line: /USER/SBIN/CRON (WEB7) CMD (/var/www/clients/client2/web7/autoresponders/chg_vacation_msg) but no errors I don't know why it doesn't work.
