Обсуждение: Adjusted the hackers mailing list
-----BEGIN PGP SIGNED MESSAGE----- Hash: RIPEMD160 You may have noticed some old emails just showing up on the hackers list. They were held because their "header lines were too long." I've just changed the limits on the hackers list as follows: max_header_line_length from 1024 to 2048 max_mime_header_length from 1024 to 2048 The trapped messages were at lengths of 1030 or so. - -- Greg Sabino Mullane greg@turnstep.com End Point Corporation http://www.endpoint.com/ PGP Key: 0x14964AC8 201006171254 http://biglumber.com/x/web?pk=2529DF6AB8F79407E94445B4BC9B906714964AC8 -----BEGIN PGP SIGNATURE----- iEYEAREDAAYFAkwaU24ACgkQvJuQZxSWSsh79ACeMvld0NcYTl+2gluu4DqLa1FA bp0AoPx6rjNTXa/LT3NX3DS0do8Kk3Se =bSDI -----END PGP SIGNATURE-----

Actually, long threads tend to run into that restriction on all the lists --- it's the References: lines that get long. If we're going to increase the limit (which I agree with) please do it across the board not just for -hackers. regards, tom lane

I mean, what are we afraid of with long headers, that the mail servers will run out of memory on a 1k header? -- greg

I'm sure there's a relevant RFC somewhere about the lengths, but it's kind of a moot point. In all my years of moderating (and I've been at this longer than anyone except Marc at this point, I think), I've never seen a header long enough to warrant 10240. - -- Greg Sabino Mullane greg@turnstep.com End Point Corporation http://www.endpoint.com/ PGP Key: 0x14964AC8 201006171348 http://biglumber.com/x/web?pk=2529DF6AB8F79407E94445B4BC9B906714964AC8 -----BEGIN PGP SIGNATURE----- iEYEAREDAAYFAkwaYBwACgkQvJuQZxSWSsiz7gCgmRZ9Wuig0YE3p4+84aw4brhd fGwAoJj392QTXQ6WKollxcuzA3XsfrLM =GYLI -----END PGP SIGNATURE-----

If we raise it to that we'll probably never have to worry about it again. If you raise it to some smaller value just large enough for the current violators it'll come up again sometime and we won't have accomplished much. I'm on a hundreds of mailing lists, this is the only place where I've seen where people keep bumping into all these arcane limits. Either other mail server software don't impose these limits or they're generally set high enough that you never bump into them. We seem to have lots of these limits set just barely high enough to let 99% of our mail go through but regularly annoy us with unnecessary problems. -- greg

So coincidentally I just saw this somewhere else for the first time. Their limit was 32k and they're raising it to 64k due to an entirely legitimate email which exceeded the 32k limit. -- greg

Yikes, that's a crazy long line. We'll have to agree to disagree though, as I'm not inclined to spend the time adjusting this again. If the limit is hit again[1], I'll raise it. Or the other admins are free to raise it if they want.
