Crash getting message sequence with error: Mailbox has more messages

ddeboer/imap version	1.12.4
PHP version	7.4.32
IMAP provider	pec.it

Summary

I'm facing a mailbox with 1523650948 messages and when I try to get the message sequence [1:2000] it crash, I tried to reproduce with openssl access and I'm able to get this message sequence.. Is there a way to fix or avoid this behaviour?

Current behavior

when I call $messages = $outerMailbox->getMessageSequence($uidRange);

I got this error:

Ddeboer\Imap\Exception\InvalidSearchCriteriaException:Invalid sequence [1:2000] imap_alerts (0): imap_errors (1):

• Mailbox has more messages (1056880) exist than maximum (1000000) at .../vendor/ddeboer/imap/src/Mailbox.php:157

I'M trying to debugging and the issue seems related to:

$result = imap_fetch_overview($mbox,"1:{$range}",0);

Since I don't have a mailbox with one and a half billion messages, I cannot reproduce the bug.

If you find a solution, please post it here so we can discuss on it
