According to the Google postmaster I know, such traffic is saved in the "spam" folder. GMail users should check there. Posts may also get checked for sufficient spamminess to be discarded, but valid traffic from lists like this one should never be discarded according to my source (as of some months ago). > As to why some get junked, and others do not, I can't tell.

In fact, it is nowhere near good enough for yahoo.com, since they leaked several hundred million address books to spammers a few years back. They really do need serious authentication, not just "it seems to be via a list", which is way too easy for spammers to simulate. Mailman (www.list.org) is working for the next Mailman 3 release (hint to users-owner) to provide serious authentication in the form of ARC processing in the distribution, which will help. ARC (authenticated received chain) allows mailing list hosts and other forwarders to sign the mail including authentication results for DMARC, DKIM, and SPF, and receivers (including Google at least among the big providers) who participate in the ARC protocol then have the option to trust the signed Authentication-Results field and the list's ARC-Seal instead of the (usually broken by list changes to Subject and text) SPF and DKIM results. If users-owner and/or postmaster happens to be listening, you can get in touch with me directly for specific information and/or help. If not, I'll try the standard places later. (Jus' plain folks who are interested should join the mailman3-users@xxxxxxxxxx list, where I'll be happy to discuss.)
