Unable to setup SM IMAP account in MacMail & Outlook for Mac

I have an issue getting Mac clients set up with IMAP in MacMail and Outlook for Mac.

We're using build 8451 on our server.

The IMAP ports are set for:

Incoming 993 with SSL

Outgoing 587 with SSL

We're using the same name for both incoming and outgoing servers.

Thinking that it may be the SM version causing the issue, I tried setting up MacMail using our test account on the SM Linux Beta server I have setup with build 8930. I had the same exact issue.

The MacMail client will connect to the incoming server, but not to the outgoing server. The Mac mail connection doctor shows "Connection and login to server succeeded" for the incoming IMAP server.

The Mac mail connection doctor shows "Trying to log in to this SMTP account failed. Verify that the username and password are correct". They are correct, I've double and triple checked.

I believe this an issue with Somoma 14.5, but I'm unsure what has changed with that version in regards to IMAP.

The client did reach out to Apple and they replied with this.

"A server setting is not compatible with Sonoma 14.5. Check your firewall and antivirus."

A Google search did not give any insight. I didn't find any thing in this forum regarding this issue either.

Any help would be appreciated.

You could be facing a mismatch between the versions of TLS/SSL the Mac supports and the TLS/SSL versions supported by the Windows server that hosts SmarterMail potentially. Do you know if they have a common cipher suite available?

Hi Kyle,

I checked and both our server and MacOS Sonoma support TLS 1.2, TLS1.3 and the same cipher suites.

Any other thoughts?

Have you guys tried to set up an IMAP account with MacOS Sonoma?
