You would have to select the outbound SMTP server for each account, but not for each message. If you have multiple IMAP accounts setup in OE, then the from line has a drop down box to allow you to select which account you are using to send the message.
I think IMAP is superior to POP3 because it more gracefully handles access from multiple locations. However, IMail has had long standing issues with IMAP, mainly a problem with "invisible mail." Ipswitch's techs swear to me that upgrading to 7.04 will fix this, so we just made the upgrade.
