syslogd and sendmail question: I removed maillog

I changed the timezone in my system and decided to start over with the
mail log.  Without stopping sendmail, I removed /var/log/maillog.  Then
I stopped it and started it.  I did not see a new maillog being created.
I then restarted syslogd.  And also restarted sendmail.  Still no
maillog.  I tried touching maillog and set the same permissions as the
old file, which I renamed.  No messages written to maillog this way.  I
looked at /var/log/messages to see if maybe mail messages were being
logged there---I saw some, but they were still in the previous timezone,
so they were not new.  I'm puzzled.  How wrong was what I did?
