There was a list outage not so long ago. Mailman crashed and lots of mail was queued up. I don’t believe any mail was lost at that time. I don’t remember the date, but 23 May could have been it and it lasted for maybe half a day before I noticed it. Fortunately this happens very rarely.

I checked the e-mails for Adam specifically over the past few days and they were all delivered within ca 10 minutes. That is the usual turn-around time for sending 1154 emails.

On the other hand, every now and then a big mailhost decides they don’t like us, and refuse our emails for half an hour or up to days. I have given up on contacting them as they never respond. E.g. cox, gmx, airmail <http://airmail.net/>, cloudmark <http://cloudmark.com/>.  After a few days, sendmail gives up and the particular subscriber will lose that message. At least google and microsoft have decent postmaster tools which I can monitor.

One particular thing that I see quite often is:
- ‘a’ responds to a list message from ‘b’ and  CC:’list’. Like this message.
- ‘b’ receives response almost immediately (as it doesn’t go through the list but through a’s mailhost directly).
- ‘list’ takes a while to resend and after 10 minutes (or 3 days if you are on cox.net <http://cox.net/>) delivers it to ‘b’.
- Mail program from ‘b’ sees: hey, this is the same msgid, no need to bother the boss again.
- Confusion, because the thread looks out of sync somehow.
(But I don’t think this happened in Florian’s example.)

But please, keep on reporting these kind of things. I appreciate that, and I always take these reports seriously and start checking log files etc.
