Exim doesn't "update the quota field". You've told Exim to ask your
database what the quota on the mailbox should be.
I think you're really asking "How does Exim know how big the mailbox is,
if it's a maildir?"
If that's your question, here's an example:
local_delivery:
[...maildir-based appendfile options...]
quota = [...your mysql lookup...]
maildir_tag = ,S=$message_size
quota_size_regex = \N,S=(\d+)\b\N
This causes Exim to
1) Append ,S=nnnnn to the filename of every message, where nnnn is the
file size in bytes.
2) Check these appended "tags" to calculate the size of each message
file, instead of using the more expensive stat() call.
See "Operational details for delivery to a new file" in the
documentation.
