The mailing list for listmasters using Sympa

[Chris Kay <address@concealed>]

As a follow-up for those with Exchange Online in-house, how do you handle:

• Integration with GAL
• Using Sympa groups (especially ones with nested Exchange DLs) for Outlook calendar invites?

Hello all!

 

I’ve been tasked with setting up Sympa as a POC in my company. Here are some specifics:

• Proofpoint is our spam/malware gateway
• Office 365/Exchange Online is our mail service; we already have a bunch of DLs, M365 groups, etc.
• Okta is our IDP

 

Here’s what I’d like to accomplish:

• Login does not require being on VPN, but does prompt user for Okta credentials
• We’ll use subdomain like listserver.contoso.com and point MX to Proofpoint

 

Here are a few questions:

• How do I nest EXO/M365 groups in Sympa lists? Just use email address and make sure it is able to accept external email?
• How do I integrate Sympa lists into our Global Address List (GAL)?
• Anyone have experience using Okta, perhaps with CAS?
• I’m pretty sure the Proofpoint workflow will work but does anyone have experience with that setup?

 

That’s all for now.

 

Thanks!

Chris
