The administrator of the mail server has the authority to set email

Postfix, Dbmail, and PostgreSQL, setting the quota to 0 allows a user
to have an unlimited amount of space on the mail server for emails.
Otherwise, quotas on each user account is set to some reasonable
amount of server disk space.
Once a user hits his quota limit, the user is required to clean up
his emails in order to continue using his email account on the mail
server.
You might talk to your administrator to see if he/she would remove
quotas on your email account(s) by setting them to zero, or raise the
quota limit on the account(s) over quota.
I have administrative access to set quotas; I can use CPanel to do
that for my domain. I do set quotas on most accounts as we have
limited space, for each megabyte of which we have to pay. It is better
to cause one mailbox to overflow than to potentially flood the entire
domain space allocation and bring all email access to a screaming halt.
I know when an account goes over quota, when a user informs me his
account isn't working, and I check his quota status, and see its over
limit. I then ask the user to clean up his emails to free up disk
space, or in some situations, I up that users quota. Some accounts are
set to unlimited emails.
Do you know exactly the account(s) causing the problem?
Several accounts are departmental; intended for access by all
department members. Therefore they have to be set to retain email on
the server for some number of days to ensure that all users can
download them. Other accounts are used by the same person on multiple
clients at multiple locations; all but one of those locations must
retain email for some number of days.
OK. That sounds fine.
In that particular scenario (single user, multiple locations), webmail
could be used, but I have yet to see a webmail interface that isn't
slow, clunky, and somewhat error-ridden, even when used on a
high-bandwidth service. Fat-client email applications are just faster,
more flexible, and more reliable.
Yes, a html email client like Squirrelmail or gmail is usually slower
than a gui like Thunderbird running on the desktop, as the html email
client refreshed over the internet, but that's not your problem.
Nothing slows down an email server faster than a system without quotas
that receives heavy traffic, much of which is span, and allows accounts
with millions of emails. LOL.
