I don't know about "successfuly" (and IANASA--I am not a sysadmin--so I don't have deep insight into that side of the process here), but we are in the middle of rolling out Exchange alongside a traditional e-mail service. > > Some of the requirements would be: > > 1) It would not matter which system managed your mail, your email > address would be the same.

Exchange is serious nanny-ware--apparently, it insists that it be the master mail server for its domain, and it has no facility to auto-forward or to set the sender to another domain. Here's our hack, AIUI: (1) Our main mail server is (I think) sendmail plus an IMAP server. (2) We have an automatic alias-table manager. There's a Web page that users can visit to set whether they get mail in Exchange, IMAP, or both, or elsewhere. Mail is forwarded from the main server to wherever the user wants to read it. I don't know where we got that feature--it may be home grown. (3) Exchange users have a separate e-mail address. (4) Exchange users cheeky enough to want to set their return addresses rather than reply-to set up a send-only account that sends mail out via our SMTP server. They need to watch out for the address they use for outgoing mail, though. Occasionally, mistakes are made.

We are using the Exchange global contact server for this.

Lotsa luck! Actually, our Windows users are mostly moving to Outlook, whatever they choose for reading e-mail. It's not a big change to switch mail reading styles if you use the same client. Most of the other features of interest are enhancements. > > Any thoughts would be greatly appreciated > > -Paul -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list
