I just install Zimbra and it is working great. Except for one thing that outgoing email through SMTP from Wordpress is not saved in the Sent folder. Here are the details:

- I just switched from Zoho mail to my own Zimbra server. I'm running Wordpress with SMTP plugins. Outgoing messages were saved in Sent folder.
- I test Zimbra SMTP with Android email app, and the message is saved in Sent folder.
- Outgoing email from website is also saved in Sent folder.

However, when Wordpress sent email using SMTP, the message is sending out fine, but it doesn't save a copy of the message to Sent folder. I hope someone can help me on this issue.

Thank you.
