Is there an option to either:

1. Use the Mail application as an IMAP client to an external server?
2. Add a 3rd party mail client into the EGroupware UI (e.g. RainLoop, RoundCube)

Our current desktop email clients (Thunderbird, Outlook) fetch mail from multiple source domains, so use the “combined Inbox” model. I was wondering if we can use the Mail app in this mode – as an IMAP client to an external server rather than the one installed with EGW. If not with multiple external IMAP sources, then maybe with just one, such that we can specify, per user, an external IMAP server, login, password, and SMTP details?

The motivation for this setup is to take advantage of the local Calendar, AddressBook, Notes, Tasks data-tables, and sync via ActiveSync to the other platforms (androd-native calendar/contacts/notes/tasks & standalone Thunderbird+Lightning), all while having the use entire eGroupware platform.

I realize that I could try move entirely off our other email servers (say move mailboxes with ImapSync, et al); but that would be difficult with large sorted mail folders. Just asking if there’s an option to not use the bundled Dovecot/Postfix server. Thanks.

Stefan,
I am glad to hear that the mail app in EGroupware is an IMAP client. would you please explain where I can specify my IMAP server’s hostname, login name, password, and security mode (TLS/SSL, port#). So far all I have found is from the sysop > admin > mail > hostaname:port#, and user’s account page email address. This is missing the user’s IMAP login, password, and doesn’t let each user specify their own server. Does EGroupware/mail restricted to one IMAP server for all accounts, and assume the user’s Egroupware login is the same (matches) the user’s their email-address & same password?

There it is – that’s exactly what I was hoping for. (It’s a bit hard to find since we don’t often see the context menu utilized in browser interfaces… But you’re employing the context menu is one of my reasons for liking EGroupware so much! )

Ok, next question… Is there a way to disable the requirement for IMAP METADATA extension? (RFC 5464)
The IMAP mail server I’m using doesn’t support METADATA extension. EGroupware mail app gives me an error: “An error happened! The server does not support the METADATA extension.” It now shows me all of my IMAP folders but none of the contents (emails).

Indeed I had, thinking that field had something to do with configuring an IMAP server globally (for all user accounts). Clearing Push-Notifications field solves it.
Thanks!!!
