the other...just for testing back and forth

hi Bob,
now I'm also thinking about just logging rado in on both machines...only
do email on the one that's got the roaming ip or vice-versa...probably
leave the master alone and just do everything from the slave.

..reminds me Bob, when I clean up the code, I want to send you these
files and let you pick them apart for me if you will. ...looks like
spaghetti right now

Instead of closing port 25 completely it may be wiser to let Sendmail
keep running but to prevent it to accept incoming mail. One way to do so
could be to stop a milter service - i.e. if you have clamav-milter
running - and let Sendmail then report a temporary failure to the sender
MTA.

Alexander

ummmmm, I like that too! thx again Alexander  ...and yes, I do run
clamav-milter

k thx u2 for the help
