Postfix sendmail -bs shows no output - permissions?
- by Tatu Ulmanen
When I run the sendmail -bs command as root, I get the expected output:
$ sudo sendmail -bs
220 mydomain.com ESMTP Postfix
ehlo localhost
250-mydomain.com
250-PIPELINING
250-SIZE 15728640
250-ETRN
250-ENHANCEDSTATUSCODES
250-8BITMIME
250 DSN
But when I run the same command without sudo, I get no output at all and sendmail doesn't respond to any commands:
$ sendmail -bs
ehlo localhost
quit
wtf
^C
$
How can I configure Postfix so that sendmail works for every user (or at least for some specific users)? I need this because SwiftMailer for PHP uses sendmail -bs for sending mails and fails when it can't find any output.
