Not sure about Mail in original MacOS 9.1.x or 9.2.2, as they both are considered
Obsoleted and unsupported; however you may be able to use Gmail in a browser
such as one offered for pre-X systems from the maker of TenFourFox.

Settings to negotiate web based email in a browser or in mail client applications
need to accommodate the provider's method of hand-shake with their servers.

Some older browsers offer the email feature built-in, such as early SeaMonkey.
These were an alternative to Explorer for Mac and associated applications.
In a box somewhere I still have copies of or originals of Classic applications.
Most of my software from that era was included with the computers I repaired
and donated; so they each had system software and apps to run.
{A side note, you could see about buying an official Mac OS9.2.2 install/boot disc from
a reseller, to have it on hand, http://store.fastmac.com/index.php?cPath=10_5_6
this from lowendmac.com site where they have some vintage/obsolete information}
Your early White iBook (dualUSB) 12-inch G3 (snow) was first in series that later
shifted to PPC G4 processor, and could dual-boot early to early OS X. That system
is not necessarily recommended (my DualUSB white May 2001 iBook G3 had 9.2.2
and OS X 10.3.9) due to lack of RAM upgrade and need for larger capacity HDD.
I was able to install from gray-label, the OS X 10.3 from an eMac G4 into my G3
white dualUSB 12-inch first edition snow built in May 2001; as a test. the actual
software packet was cast-away and the original owner trashed the computer...
So while it is possible to adapt different OS versions to run in these, they may not.
And the need for RAM in chip, and larger internal storage drive, as far as they go
are essential to better expand whatever is left of their flexibility.
These cannot accept a very large HDD due to hardware limit or power demands. A
newer OWC Mercury Legacy Pro (IDE/ATA) SSD may be adapted, to run in these.
In some instances, and older computers, partitions may be required to run the OS.
The obsolete nature of email client software may run into a brickwall in some attempt
to run it; however there are some users who have adapted and some have found a
build for older Mac of linux or other OS an alternative. Or a diversion from later OS.
Hopefully DB Aqua or other vintage experience users may see your post & offer
better ideas; I've not had an iBook G3 DualUSB 12-inch running MacOS 9.2.2 &
OS X 10.3.9 for quite awhile. After having it restored by wegenermedia, I sold it
to an 85 y/o guy, it was his first computer and he wrote letters to editor & other bits
online using dialup modem. (I used it with AirPort Extreme base with 56k modem b.i.)
Good luck & happy computing! 🙂
