Hi. This is the qmail-send program at sv1.dattasolutions.com.mx.
I'm afraid I wasn't able to deliver your message to the following addresses.
This is a permanent error; I've given up. Sorry it didn't work out.

<root@sv1.domain.mx>:
Sorry, I wasn't able to establish an SMTP connection. (#4.4.1)
I'm not going to try again; this message has been in the queue too long.

It's warning from your server where something wrong (in this context is no 'www-data' userid).

Open /etc/logrotate.d/haiwatha and then remove 'create 640 www-data www-data' line.
