Yahoo! defers mail from my domain. When the mail finally arrives it seems to end up in bulk folder of Yahoo! customers. This means a) that mail arrives late and b) you might not see it if you just clear the bulk folder. Yahoo! does not react to complaints.
Mail delivery to most other domains works perfectly.
To combat Spam, the mailing lists are semi-moderated. If you post from your subscription address, mails will go through unmoderated. If you post from another address, your mail will be sent to a human moderator for approval. Due to the large Spam volume moderation is imperfect and your legitimate mail might be lost, so please post from your subscription address if at all possible.
m4-breakers: Anything related to the M4 Project. General discussion, problems with the software or with the installation.
m4-devel: Development of the client software, testing.
m4-announce: Important announcements. This list is read-only and low volume.
The lists are handled by the ezmlm/idx mailing list manager. The following examples apply to the m4-breakers list. For the other lists, replace breakers with devel or announce.
