As a Linode (now Akamai) user myself, I can confirm that they have "Issues" with the reputation of their IP address spaces, especially their IPv6 address space. They've been very liberal and helpful in helping us stay connected, as they have for many others, and I've corresponded with them about this issue. They're not doing anything wrong, and crack down on spammers using their cloud servers, but it's not the kinder, gentler Internet of yester-year, and they're, to an extent, caught in the middle. On top of this, MS Outlook servers are, and have been for a long time, a real PITA, notorious for long time for blocking emails on very flimsy grounds. To the best of my knowledge, there's no fix for this at the list-server level. The bottom line seems to be that the only email services which work consistently with all recipients are those with deep pockets - Gmail, Yahoo, Microsoft email, etc. If you have the money, you can buy a better reputation for your IP addresses are address group, but it's a money game. -- Lindsay Haisley | "The first casualty when FMP Computer Services | war comes is truth." 512-496-7118 | http://www.fmp.com | -- Hiram W Johnson ------------------------------------------------------ Mailman-Users mailing list -- mailman-users@python.org To unsubscribe send an email to mailman-users-le...@python.org https://mail.python.org/mailman3/lists/mailman-users.python.org/ Mailman FAQ: http://wiki.list.org/x/AgA3 Security Policy: http://wiki.list.org/x/QIA9 Searchable Archives: https://www.mail-archive.com/mailman-users@python.org/ https://mail.python.org/archives/list/mailman-users@python.org/ Member address: arch...@mail-archive.com
