"Invalid Email Address" error - Zimbra Desktop - IMAP configuration

[dream_liner2k2]

Hi,

I've just installed Zimbra Desktop on Xubuntu 11.10 and configured 2 accounts :

1st Account- POP Account - a POP account (non-Exchange server), and

2nd Account - an IMAP account(Exchange server account configured as IMAP).

No issues with receiving the mails for both accounts.

No issues for sendng mails from POP account. (1st Account)

But when I sent mails from IMAP account (2nd Account), I get NDR with "invalid email addresses" error. However, there is no such problem of sending mails when I send from Outlook Web Access, or Outlook (configured as Exchange Account and also Outlook Anywhere (RPC/HTTP).

Please throw light on where I might've gone wrong.

Well, I figured it out.

Its got to do with Permission Groups on the server for the SMTP receive connector and not just with SMTP send connector.

That resolved my problem.
