Today somebody sent me this bounce: --- snip --- Generierender Server: s-mx16-dhz01.charite.de
somerecipi...@innere.med.uni-giessen.de mail-cvk.charite.de Remote Server returned '550 5.6.11 SMTPSEND.BareLinefeedsAreIllegal; message contains bare linefeeds, which cannot be sent via DATA and receiving system does not support BDAT' --- snip --- So, s-mx16-dhz01.charite.de is an internal Exchange Server relaying via mail-cvk.charite.de on the way to the internet. The interpretation of this bounce is "mail-cvk.charite.de" rejected the mail with the status code: "550 5.6.11 SMTPSEND.BareLinefeedsAreIllegal; message contains bare linefeeds, which cannot be sent via DATA and receiving system does not support BDAT" But -- that's not a postfix error message. In fact, this looks more like an exchange error message.
