Mailbox has more messages (.......) exist than maximum (....)

[ivanghisleni]

From manual page: https://php.net/function.imap-fetch-overview

I'm facing this error and I don't know how to solve it..

PHP Notice: Unknown: Mailbox has more messages (1057204) exist than maximum (1000000) (errflg=2) in Unknown on line 0

PHP version: 7.4.32

Code:

<?php

$mbox = imap_open("{******:993/imap/ssl/novalidate-cert}INBOX", "*****", "*****")
     or die("can't connect: " . imap_last_error());

var_dump("Listing");

$MC = imap_check($mbox);

$range = 20;

var_dump($MC->Nmsgs);


// Fetch an overview for all messages in INBOX
$result = imap_fetch_overview($mbox,"1:{$range}",1);
/*foreach ($result as $overview) {
    echo "#{$overview->msgno} ({$overview->date}) - From: {$overview->from}
    {$overview->subject}\n";
}*/
imap_close($mbox);

Some quick Googling says that the library PHP uses for imap support isn't able to handle more than 1M messages in a single folder, and that you're probably running into performance issues because of how many there are.

1M messages is too many for a human being to deal with. You probably should set up some inbox filtering and processing rules to distribute your messages into folder categories.
