Actually, I find the V to E on the 5000 to be very easy... not 3300 easy, but pretty easy... If you go to the email settings and press F1 for help, everything you really need is there, same with the settings on the mailbox. I haven't seen a more clear document on how to set it up, although it does take a little playing with it (and sometimes looking at the logs for a bit) to get everything quite right.
But I can tell you, your settings as they are should NOT work... In EMail Gateway settings, the EMail SMTP Server settings must be a DNS-resolvable domain name, IP addresses are not allowed. You probably have more info in that area than is really needed too.
Also, for Enhanced Integration (not basic Forward or Copy&Forward) you are missing some fields in the mailbox, you must have a DNS-resolvable domain name of the mail server (ie. mail.mycompany.com), the username and password of the individual on that system, remember this is basically using an IMAP mail connection for that specific mailbox and is not like a BlackBerry Enterprise Manager connection. Basic Fwd or Copy&Fwd doesn't require any of those fields on the user level except email address, and will just pass the voicemail message to the SMTP server set in the Email Gateway settings.
When issues arise in configuring this, best to check the logs via the web portal, look ad the avdaplog.txt logs to make sure the voicemail is being converted to an email and the attempt is made, then check the maillog (or mainmail or mail.mainlog file depending on the system version)
So, that being said, try to get the basic (FWD or Fwd&Copy) working first... Generally all that is needed is:
IP Settings:
Base Server Hostame: Mitel5000 (used with the next option)
Domain Name: rednecks.com (added with above and presented as "HELO Mitel5000.rednecks.com" to the SMTP when sending emails)
DNS Server Primary Address: A.B.C.D (Must be a DNS server capable of resolving the Email SMTP Server name listed below)
Email Gateway settings:
Administrator Email Address: This is the "RCPT FROM:" email address in SMTP
Email Real Name: Voicemail (or other user friendly name, optional but recommended)
EMail SMTP Server Port: 25 (if other ports are required can be changed, but authentication is not supported other than PLAIN, LOGIN, or CRAM-MD5)
Email SMTP Server: mail.rednecks.com (MUST be a DNS-resolvable domain name, IP addresses are not allowed)
Email System: SMTP
Email Username: username (Optional, only if the SMTP server requires PLAIN, LOGIN, or CRAM-MD5 authentication, the preferred method with Exchange is to allow anonymous relay from the Mitel 5000's IP address and use no Username/Password)
Gateway Password: password (if required, see above)
Then in a user's mailbox (1000 for example) Email Synchronization settings:
Email Synchronization Level: Forward & Copy (always try this until you know everything is working)
Email address for Voice Messages: billybob@rednecks.com (or any valid email address, preferably one residing on the email gateway initially, this will be presented in the MAIL TO: SMTP field)
Email Client Message Format: WAV (Don't use MP3 unless absolutely necessary, it really eats up processing power and conversion time, especially on long record a call sessions)
This should produce some kind of results and be duplicatable with success on multiple mailboxes or consistent failure, if failure then the various mail.xxx files in the logs should be useful to see where and what failed. If you can't get anything to work, try it manually via telnet from a PC on the same subnet as the 5000, this site can be useful for that:
