Nope, it was during the weekend.

Server error message.

Everyone (including me) is _supposed_ to use the ISP's smarthost.

I don't think so.

_All_ the swen mails I got are of this type. All the ones I don't get
are blocked by clamav (amavis).

I'm back with my ISP again. They resolved their problem (apparently) and
I couldn't send mail to a particular domain which told me that 'your
Host has no Name'. Well, great. I _think_ it has to do with the fact
that resolving my domainname to my IP address works (via DynDNS.org) but
the reverse lookup returns xx.xx.xx.xx-customer.isp.nl. Nice, :-/
