Microsoft Exchange Server predicament
Posted on 2006-06-10
Just contacted by a new client who had another consulting company setup their Windows 2003 SBS. They had configured each user's Outlook with 2 accounts: the POP3 account for external mail to their external email host as "default" and the Exchange server account for local mail as the 2nd account. They configured the internal domain with a ".local" top level. Mail is being returned at times with #5.7.1 - (meaning unable to relay) and also "unknown domain .local". The consultant claims the email was working both internally and externally for everyone before she left. I don't know how she was getting everything to work in this setup because if you make the external POP3 acct the default then all mail will get routed to the external email host and the local mail will get dropped as unroutable. If you make the Exchange acct the default then all mail will route locally and the external mail will never get out to the POP3 host. I don't think it was really all working for everyone. The next thought would be to only set up the Exchange acct in all users' Outlook, and configure a POP3 connector on the Exchange server. This would work, but the problem is when all external mail reached the POP3 email host they are unable to translate from the ".local" to the "com" domain for the client so external mail would get blocked by recipients. the reasons to use Exchange is ease of use with Internal email for clients, storage of all email on the Exchange server(without having to resort to .pst files locally) and more importantly shared calendars. For this reason alone I am trying to preserve Exchange. I'm pretty much left with nothing but teloing them to bring the email server inhouse and get a static IP unless someone can come up with other suggestions. Any thoughts are appreciated!!
