My professor came to me today saying that his collaboration members were complaining that they (some of them) received mail from him with an 8 hour delay. He asked me how come and I looked into /var/maillog where I could find that he sent said mail at 12:25. The recipients were some users@host and somealias@domain. The users@host received their mail immediately. Only the aliased (at the destination) recipients were suffering from that long delay. As I understand, sendmail resolves the host and contacts the host's sendmail directly to deliver the mail, right? What happens in the case of the host portion actually isn't a host but a domain? Does sendmail send to the smart host (DS macro)? Or does it deliver to the host specified by the MX record in the nameserver if the nameserver has a MX entry? I'm trying to locate where the enormous delay came from. Can it be seen from the headers at the receiving site? --Chris Christoph P. U. Kukulies kuku@gil.physik.rwth-aachen.de
