[sombatos]

Starting February 15, 2021, G Suite accounts will only allow access to apps using OAuth

Ouch :\

Hi I am are using your library to get emails from gmail. I want to switch to googles new oauth system quite soon. Is there any progress on this issue for ddeboer/imap?

[Slamdunk]

No one is working on it, as far as I know

[croensch]

I believe ddboer/imap can do nothing unless something is done to the PHP extension: https://wiki.php.net/todo/ext/imap
TL;DR ddeboer/imap only gives the basic auth to the extension and the extension gives it to an old C library not written by the PHP community

[Slamdunk]

This gives me hope: https://wiki.php.net/todo/ext/imap/xoauth2

There are also some workarounds for G Suite: https://medium.com/@freescout/oauth-2-0-g-suite-microsoft-365-and-php-7da16ca74314

Huh, nice, I've always used App password indeed.

I consider this topic closed.

Hi! @Slamdunk @freescout-helpdesk @croensch @LinusBrockmeyer @sombatos

The strategy to overcome the problem is replacing all the imap_* functions with the equivalent imap2_*

• imap_open(...) become imap2_open(...)
• imap_getmailboxes(...) become imap2_getmailboxes(...)

etc...

The idea behind the imap2 library is to replace the core php imap extension with a new one written in PHP.
Why? The problem is related to the UW-IMAP https://github.com/uw-imap/imap it seem outdate from 2019. There are many security concerns about it

I'm waiting from your feedback! I hope that imap2 is a good replacement for imap

[Slamdunk]

Hi @francescobianco, I guess you are referring to your library https://github.com/javanile/php-imap2

I have to say App passwords are now well spread and supported, so I'm not intended to change this library auth methods.

[francescobianco]

Hi @Orgoth , please, get you a chance to PHP-IMAP2 (https://github.com/javanile/php-imap2)
This is a FULL implementation of standard PHP IMAP functions like (imap_open, imap_getmailboxes, imap_*, etc...)

This was full tested, every input to imap2_* functions get back the same output of imap_* equivalent

• https://github.com/javanile/php-imap2/blob/main/tests/CompatibilityTest.php

The IMAP2 works well with OAUTH

• https://github.com/javanile/php-imap2/blob/main/tests/XoauthTest.php

This libray can be installed with composer

composer require javanile/php-imap2

This libray introduce a easy way to replace the old PHP-IMAP with new one:

JUST replace all imap_(...) functions with imap2_(...)

NO OTHER AMENDS are required.

Please give me the opportunity to make my sacrifices useful to the community.
