Hello, Since last week, I'm not receiving any mails from the Haskell mailing lists (haskell@, haskell-cafe@ and beginners@) at work. (I'm temporarily using my GMail account now) I checked with the guys in our IT department what's going on, and it seems like the Haskell mail server lambda.haskell.org is not (re)configured as it should. The relevant log message on our side is: reject: RCPT from lambda.haskell.org[78.46.100.180]: 504 5.5.2 <lambda>: Helo command rejected: need fully-qualified hostname; from=<haskell-bounces@haskell.org> to=<kenneth.hoste@ugent.be> proto=ESMTP helo=<lambda> Apparently lambda should be responding with "helo=<lambda.haskell.org>" (or somesuch) in order to make the mails pass through on our end. We have a pretty strict anti-SPAM policy, and I was told that not using a fully qualified hostname as helo response is a common characteristic of spam servers. Can someone look into this? greetings, Kenneth
