As some of you may have noticed, myxwiki.org mail sending comes and go these days. The source of the problem is that our hoster keep flagging some of the mails it’s sending as spam and when that happen it block the whole thing until it’s sorted out.
We suspect it might be related to mails sent with a non @myxwiki.org address in the FROM, which is configured in some of the subwikis (the default is no-reply@myxwiki.org). So it’s possible we decide in a near future to prevent the customization of mail setup in subwiki and block any mail not sent with the default FROM.
