I'm not aware of email services using sync regularly.
In my experience

the critical factor (for > 600 messages/sec

matter :-)
Performance of the disks for the mail messages
themselves is not as
critical.
I'm not using database. I'm using qmail only. Sync don't matter?
I've not implemented qmail, but it appears to be just an MTA.
These do store-and-forward, so it is unlikely that they need to
use sync calls. It will create a lot of files, but that is usually
done async.
