I just joined Experts-Exchange mail list. It is good to be here with you.
I will start off with my Problem:
I have an Exchange 2000 Server running on Windows 2000 AD. What has happend quite often is the server goes down for any reason (Virus/Partition full of logs etc) and users can't send/receive or access their mail, because all messages are inside the Exchange 2000 database.
I cannot dump exchange, because users want the features it has(Calendar/Meeting request etc) My Exchange server is having lots of hardware problems and I was told I cannot buy another server. I am in pretty crazy situation.
All clients are purelly using SMTP for delivery and receiving emails.
I need to build some redundancy; and I thought would be possible to do the following:
1 - Have an ordinary PC running Linux and integrated into the Windows 2000 AD using SAMBA 3.0/Winbind, kerberos and LDAP.
2 - Have a Linux mail server integrated into the AD, receive all mail deliver them to Exchange and keep a copy and in case the Exchange goees down all users would sendand receive emails through the Linux mail Server.
1 - Exchange database is a file and all mailboxes are withing this file (Information Store)
2 - Outlook clients are linked to this exchange mail server and all mailboxes are within exchange.
How possible would be to, place the Linux Mail server in front of the Exchange 2000, and then; deliver the messages to the Exchange box, and if the Exchange box goes down, allow clients to send and receive through the Linux server.
I have already setup the linux box and integrated into the 2000 AD. It is a Debean distribution, samba 3/winbind, and I am thinking of using Exim for the mail server.
Another problem I came across: Once the mails are in the QUEUE on the Linux mail server, I cannot deiler them to a local mail box, because the mailboxes are within Exchange 2000.
Please if someone have or had simillar problem or thought, I would really appreciate any help or ideas.
Thak you very much in advance
