We have some remote users, who need access email from their emailboxes, and also they are needed sent emails to internet recipients, and to groupwise system recipients.

There is no problem with receive email with pop3/imap.

But Ive no clear understanding how to remote users can send email with smtp. I can enable smtp relaying and restrict ip addresses for relaying, but in this case Ill not have sent items stored in groupwise emailbox.

Is it any ideas how remote users can sent email by smtp, and they will be stored in sent items it user emailbox.
