    Try checking your mail log file (/var/log/maillog), for possible problems.

    signal 15 is sigkill, which if you didn't invoke it means that system is not happy about something. sounds like its crashing. Perhaps a mismatched library. Did you update recently? How is your system doing on memory? Check out /var/log/messages, perhaps it contains more information on why the postfix process is crashing.

    Does it give you any output when restart the service?
    Code:
    service postfix restart
    or
    Code:
    /etc/init.d/postfix restart

    What does your system say about the messages in the queue:
    Code:
    postqueue -p
    you can also look for out of place variables, by turning up the debug as well.
    Code:
    postqueue -v
