Greetings,
We've been using mailman for almost ten years (thank you). At our peak we have run about ten email lists: some discussion-oriented w/ small membership, and very low frequency; others that have had higher frequency and membership. In addition, two of them have been used to distribute monthly newsletters/announcements to a large membership (5,000 to 10,000 subscribers).
Recently (in the last six months to a year), some ISPs have begun blocking these high volume/low-frequency distributions, in particular AOL. While AOL emails make up about 10% of the constituency of these lists, for us and our lists it is important that distributions reach these subscribers.
It seems that AOL, among others, has insisted on some sort of pre-authentication procedures, so that large distributions from servers such as ours are effectively whitelisted.
Have other mailman admins encountered these issues? Is this a foreshadowing of things to come? Much thanks.
