OK, I dont understand this at all.
I was debugging another problem, and had a 'tail -f' running on my maillog
file.
It showed data down to the present, namely 15:18:18
Something had gone by fast enough that I brought the maillog up in an editor
but IT only showed data down to 14:02:16
Looking at the 'ls' of /var/log, the maillog file shows a write date of 14:02.
If I do a 2nd tail -f, it too stops at 14:02.
What is going on with the file system to cause the bizare behaviour?
Why cant I see ALL the data in maillog, or why could I see it only once?
Confused.

What date ?

And what date here ?

I'm hoping this is as simple as:
1) You opened the initial tail on one day and left it running
2) Log rotation happens, mail software, via syslog or directly,
starts logging to the new 'maillog', the other one now being
'maillog.1' or whatever
3) You don't realise this and get confused by the differing data
when you look afresh at what is now 'maillog'
And of course, depending on local configuration, maybe your maillog
rotates more often than once a day (although that alone wouldn't explain
the 'gone backwards' timestamp).
