For the record, I sent this reply to Clemens Bier, too, but: <ClemensBier@arcor.de>: host mx.arcor.de[151.189.21.118] said: 554 Service unavailable; Client host [68.252.5.55] blocked using rbl.arcor-online.net; see http://postmaster.arcor-online.net/ (in reply to RCPT TO command) and I cannot connect to http://postmaster.arcor-online.net/. So, his ISP is blocking my mail, and he did not get my direct response. Josh
