Berkeley Lines: 58 Uh, I have a small nit to pick with John Gilmore. The example he used for showing the proper interpretation of `correct' mail headers from the UUCP land was wrong: >>For mail which has been passed solely thru uucp sites, the "From " line >>is clearly correct, since the "From:" line has not been maintained at >>(all) intermediate sites. E.g.: >> From dual!allegra!cbosgd!fair Thu Feb 23 17:01:34 1984 >> From: dual!cbosgd!fair >> >>The win would have been to make the envelope right for all uucp >>traffic, (which it already was for strictly-uucp traffic) and have >>sendmail fix the From: line to match the "From " line. This has not >>been done -- yet. Is there a uucp/mail expert in the house who can tell >>us WHY the envelope is "uucp" or some user, instead of the right thing? I have been many things in my time, but never have I been cbosgd!fair. I'm dual!fair or ucbvax!fair or fair@ucb-arpa.ARPA. The problem is that some 4.2 BSD sites out there are running bogus versions of sendmail which puts out the return address in the envelope in domain format. It gets worse when the letter passes through a working sendmail sites, because they try and undo the damage, and only succeed in hiding it. That letter there started life From dual!fair cbosgd changed that to From cbosgd!fair@dual.UUCP and allegra changed that to From dual!allegra!cbosgd!fair It gets really fun when someone tries to reply to that. This bug has been fixed by steve@nbires.UUCP, tjt@masscomp.UUCP, postmaster@uwisc-rsch.ARPA, and eric@BERKELEY.ARPA Some by my prodding them, some not. If you spot one of these, complain until it gets fixed, because all mail passing through the suspect site will have bogus return addreses, and only the silly people who keep the entire routing map in their heads (like me) will be able to get anything through the Emails.
