Connection could not be established with host mail.domain.com [Connection timed out #110]

I am on 8.2.3 on a Hostinger VPS and also having trouble fetching.
This is an old FS that I had stopped and just now turned on again. Previous settings worked (group shared mailbox) -- in that it fetched the IMAP folders and said the connection was working, and the email arrives in snappymail. Tried humptydumpty settings, also "worked", still not fetching.
Sending works fine from FS, from Snappy, etc.

openssl s_client -connect <mailsever>:993 -crlf
Since I'm using the localhost settings that HD said, I used this (note host name and alt port):
openssl s_client -connect mail:9393 -crlfGot this response:

@nebulon I've been using it as 9393, and that's how Girish has it also in the screenshots he sent me during our troubleshooting. Sending and fetching are working with 9393.
Edit: I'll try reverting to the original settings soon to test with v8.2.3.

9393 is the internal IMAP port that does not offer TLS. But my original question was to connect to the external endpoint which is the correct way to configure FreeScout.
openssl s_client -connect <mailsever>:993 -crlfwheremailserveris my.domain.com (whatever the mail server domain is)There are updated screenshots at https://docs.cloudron.io/apps/freescout/#cloudron-mailbox on how to connect.

@girish I forgot to ask, are these still the best settings to use or can we set an encryption now?
Your screenshot is still using the internal connection. The internal connection doesn't need any encryption since they don't leave the server. I don't expect the values to change but those values are still internal/cloudron implementation detail. I suggest using the settings as in the docs at https://docs.cloudron.io/apps/freescout/#cloudron-mailbox . Those use STARTTLS (SMTP) and SSL (IMAP)
-
@girish I'm referring to the app mail settings, not the mailbox. You can find that under:
Manage > Settings > Mail SettingsWhat if my FS and mailserver aren't on the same server. What app mail settings should I use? The docs don't cover the above settings page; only shows the mailbox set up.
As for the mailboxes, I set up them up as shown in the docs, using SSL and STARTTLS and they're working fine with v8.2.3.
P.S. I noticed my emails from InvoiceNinja went to the spam folder because something was off, but it looks like v8.2.3 fixed that too.

@humptydumpty ah, I am blind
sorry, the settings are correct then. Those are autoconfigured by the package. There is no security issue since the connection is entirely internal.To answer the rest, think of it like this:
-
Manage > Settings > Mail Settings- This is auto-configured by the app . I think FS sends this for password reset, invite , system email etc. All this goes internally from app to the internal mail server conection. Cloudron mail server will then deliver the email based on your Mail -> Domain -> Outbound settings (in Cloudron dashboard). This is how the email of all apps is auto-configured. the packaging logic will overwrite/change these values automatically as needed (like if we change how internal stuff works). -
Mailbox - FS can be configured to fetch emails from anywhere (gmail, outlook, etc). In that context, using Cloudron mail is just a special case. This is why we encourage to use the normal Cloudron mail credentials here. The packaging logic does not (and in a general way cannot) touch these values. These credentials won't change since this is how everyone is accessing Cloudron Email.
