color:#1F497D'>I can’t really comment on the sendmail specifics as we use
Postfix, but in general the idea should be to have your external MX record
continue to point to the MailScanner/MTA box and have your internal Exchange
server use the box as a smarthost for outbound mail.<o:p></o:p></span></p>

<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>What I do is to have as many SMTP level checks as possible done
by Postfix <b><i>before </i></b>accepting the message (i.e. RBL/Greylisting/RFC
& Format violations), and then what’s left gets put through MailScanner and
is then relayed on to the Exchange box.<o:p></o:p></span></p>

<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>Outbound mail from our specific IPs is always accepted by the Postfix
box, and we have some checks done by MailScanner i.e. Virus checks but others
are skipped i.e. Spam checks.<o:p></o:p></span></p>

<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>Postfix can pull a list of valid recipients from Active
Directory so you only need accept mail to valid addresses, not sure if Sendmail
can do this but I would be surprised if not?<o:p></o:p></span></p>

color:#1F497D'>As for Exchange, so long as you buy good, solid proven hardware
and configure it to best practices and ensure you back it up using an Exchange
Aware backup program you should have few problems – the main things to check are
that you are doing an “online” backup, that Circular logging is disabled, and
that you have a sensible deleted item retention period setup.<o:p></o:p></span></p>

<p class=MsoNormal>Hi Everyone.<o:p></o:p></p>
<p class=MsoNormal>I know this is way off topic, but having used mailscanner
for many years I have come to value your options and insight.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Anyway, I found out last Friday that management has deemed
it necessary to convert from our CentOS sendmail/pop server to Exchange on
Winblows.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I have about 250 mail boxes that I will need to convert and
I would still like to you mailscanner to pre-process all internet mail inbound
going to Exchange.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I know that some of you have gone through this conversion,
and since I am on my own to learn Exchange and windows at the same time. I was
hoping I could get some.<o:p></o:p></p>
<p class=MsoNormal>“This is the best way to do it” documents.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Any help on the following topics would be greatly
appreciated:<o:p></o:p></p>
<p class=MsoNormal style='margin-left:36.0pt;text-indent:-18.0pt'>1)<span
style='font-size:7.0pt'> </span>How to set up
Mailscanner for pre-process inbound mail to Exchange.<o:p></o:p></p>

style='font-size:7.0pt'> </span>Any add on tools
for exchange to make it run better like, reporting tools, database repair
tools.<o:p></o:p></p>

style='font-size:7.0pt'> </span>Anything on how
to set up a exchange server “Best Practices”<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>They want me to order hardware this week. Lol. I told them
I have a little reading to do first. So any help I can get from you guys would
be really helpful<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Thanks in advance.<o:p></o:p></p>
<p class=MsoNormal>Phil<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal><span lang=EN-US>PS Currently I think I spent maybe $3k on
the server I am running now, Exchange has priced out over $50K so far. LOL</span><o:p></o:p></p>
