Dear All, According to my setup i can not call |/var/qmail/bin/preline -f /usr/local/libexec/dovecot/dovecot-lda from my /var/qmail/control/defaultdelivery file, Instead making a perl file which will call the same for delivery of mails.

If i put the following code in my mail.pl |/var/qmail/bin/preline -f /usr/local/libexec/dovecot/dovecot-lda then it throws error in running file from command line.

Warning: Use of "-f" without parentheses is ambiguous at /var/qmail/bin/mail.pl line 2. syntax error at /var/qmail/bin/mail.pl line 2, near "|" Execution of /var/qmail/bin/mail.pl aborted due to compilation errors.

content of mail.pl

#!/usr/bin/perl |/var/qmail/bin/preline -f /usr/local/libexec/dovecot/dovecot-lda

Any help will be useful for me.

Thanks
