Indeed; I see something similar on lots of other mail lists ... except that elsewhere all the posts come with the workaround addresses. In one case it's impossible to tell who posted which piece of content unless the poster has a sensible sig, and even if they do one still has to scroll every post to the bottom to see who wrote it. Since my email address does make it into my posts, does that mean that the listserver sees my (Fastmail generic domain) address as "properly/securely" setup, or not? > Essentially things go wrong because LISTSERV is unable to sign (loosely > speaking) an email that it receives from a subscriber and wants to relay to > the list.

Do you mean that different recipients see any particular post with a mix of apparent from-addresses, depending on whether the listserv had problem sending copies of that post to their mail provider? -- Jeremy Nicoll - my opinions are my own. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
