Hi Zeno: I CCed you into my koha list response, but I'm getting unrecoverable errors trying to send to you. Here's the relevant line: <-- 554 5.7.1 <z.tajoli@cineca.it <mailto:z.tajoli@cineca.it> >: Recipient address rejected: Failed SPF check; prosentient.com.au, Unknown mechanism type 'ip' in 'v=spf1' record I'm guessing that your v=spf1 record might contain "ip" instead of "ip4"? I don't know much about SPF, but that's my best guess. Thought I'd try to send you a head's up about it via the listserv in any case. Maybe it's a problem on my end but it's not happening when I send email to anyone else. David Cook Systems Librarian Prosentient Systems 72/330 Wattle St, Ultimo, NSW 2007
