[R] email threads chronology

Mark, you can follow the bouncing emails by looking at the raw message
headers. How you would access them depends on your email client,
but "Received:" headers appear in reverse chronological order above the
"From:" line, indicating the times when the email had reached various
servers in its journey. Just be sure to subtract the timezone offset
before comparing timestamps to see the chronology in UTC.
The original email appears to have spent about 4.5 hours at
"phil3.ethz.ch", possibly awaiting moderator approval. The mailing list
spam evaluation headers indicate that it did not think the email was spam,
so some more basic rule or server downtime must have delayed it.
Subsequent emails in that thread appear to have come in chronological
order to my email server.
Sorry, I don't have R code to do that analysis (I did the above by
inspection), so I will shut up now.

However I did not get that email until 1:48pm, preceded by 3 replies to the post. Trivial but irritating. The preceding replies suggest this is something going on at my end, perhaps related to network security. I'm curious what might be causing it, and if there is something I can do about it - short of contacting IT staff, which is more irritating than the corrupted threads.
