2003 pop3 connector |
|
|
I need to configure a pop3 connector in Exchange 2003.
Does 2003 come with one and is it recommended? if so how to install?
I have read about 3rd party connectors.
What are your recommendations?
Thanks Aaron

There's no native POP connector in Exchange. SBS includes one, but it isn't
really part of Exchange per se.
POP connectors aren't recommended - but if you want to use one, there are
many - go forth & google! |

Why are they not recommended?

Because POP is designed for a mail client to go request mail downloads from
a mail server. It isn't meant for servers to talk to each other. Your
Exchange server can receive mail sent to it via SMTP, which is how mail
servers talk to each other.
POP connectors often cause problems - slow delivery, lost mail, loss of BCC
info, etc. I suggest you look into hosting your own mail. See
http://www.msexchange.org/tutorials/MF002.html for help - written for E2k,
but still applies. |

Thanks for that info. This server is running on a small business |
network. The reason we have chosen the run the pop connector is also for
redundancy. if the server or Internet link drops, they cant afford to
loose the mail. So it will be waiting in the pop box when all comes
online again. Also Static IP's are a little expensive here.
Does this sound relevant? |

Right. So you have someone configured as your backup - they hold mail for
your domain & repeatedly retry delivery to your server. Their server is
listed as a lower-priority/higher-cost MX record in your public DNS. A lot
of ISPs will do this, but I usually use www.dyndns.org - MailHop BackupMX.
It's very inexpensive.

You don't need a static IP. See www.dyndns.org again. Create
mydomain.dyndns.org or whatever you wish, and use that in your public DNS as
your primary MX record. Download & use one of the update service apps like
DirectUpdate, and install it on your server - it will update dyndns.org with
your current public IP automatically. This works quite well.
Since you are probably already having problems sending mail to certain
domains, since you're sending out of Exchange with your dynamic public IP,
you can set up an SMTP connector that forwards some or all outbound Internet
mail to your ISP's SMTP server as a smarthost. That way, your outbound mail
won't get blocked because it comes from a dynamic IP range - this is
becoming a common problem.

Yep - but I think I've fairly well trampled all over your current reasons
for wanting to use POP. :) |

Might I interject an alternative opinion?
A good pop3 email program like VPOP3, MDaemon
or Merak is usually an excellent add-on to Exchange
Server. Email handling in Exchange Server had
always been much less flexible and robust than the
better competing products. The only problems with
mail distribution from a single pop domain mailbox
I have seen is with mailing lists, although that can
be corrected easily with the mapping options that
all good mail servers include. I've never seen mail lost
otherwise. A big bonus is that you add another layer
of security to your email system -- you move your
incoming SMTP vulnerability to the mail hosting
system, many of which now offer extensive filtering,
which nowadays is not such a bad deal. Also, if
your really keen on maximizing security, the good
POP3 email server come with many more and
much cheaper options for email security and
filtering than Exchange. Most of them offer fully
functioning trial versions for your testing pleasure.
One good place to start to see a list of them
compared is here: http://www.serverwatch.com
