Possibility to change the check mail interval by default.

[carlosdmendez]

Is your request related to a problem? Please describe it.
I have not found an option to tell the system what the default check interval for new emails should be, and the default number "15" seems too high to me.

Describe the solution you would like
Enable an option to change the default check mail interval.

15 minutes is not too high.
In your account settings you can change it.

Keep in mind: more frequent is more server load

As I recall, many eMail client applications default to 5 minutes, and smartphones do the same, so I think 15 minutes is a pretty long time.

But many email clients have a direct (open logged in) connection with IMAP server (might use IDLE and/or NOTIFY).
SnappyMail does not. It requires: HTTP -> HTTP Server -> IMAP server -> LOGIN -> fetch

You can't compare 2 worlds. You should compare Roundcube with SnappyMail for this setting (and then they are still completely different).
Roundcube only has a few options:

And if you really can't wait for "new mail" to arrive, you can click the reload button as many times as need to.

I also consider that it should be 5 minutes.

I know I can change the interval time in the account settings, but that is not what I want.

What I am looking for is an option that allows me to set the default interval time for all accounts.

snappymail/snappymail/v/0.0.0/app/libraries/RainLoop/Actions/Accounts.php

Line 211 in e07749b

'CheckMailInterval' => 15

Can be overridden with a custom extension.

For example see the Demo extension
https://github.com/the-djmaze/snappymail/tree/master/plugins/demo-account
It has two ways for modifying:

1. json.after-accountsandidentities always overrides
2. Custom Storage engine that sets the defaults

   snappymail/plugins/demo-account/storage.php

   Lines 39 to 41 in e07749b

   	if (!\is_dir($sDataPath) && \mkdir($sDataPath, 0700, true)) {
   	\file_put_contents("{$sDataPath}/settings",'{"RemoveColors":true,"ListInlineAttachments":true,"listGrouped":true}');
   	\file_put_contents("{$sDataPath}/settings_local",'{"UseThreads":true}');
