User is over quota qmail

The infamous "over quota" error in qmail!

When qmail reports that a user is "over quota", it means that the user's mailbox has exceeded the maximum allowed size, as specified in the qmail configuration file (qmail.conf or qmail-smtpd.conf).

Here are some common solutions to resolve the "over quota" issue:

1. Increase the quota: Edit the qmail.conf or qmail-smtpd.conf file and increase the quota value. For example, you can set quota = 102400 to allow users to store up to 100MB of email.
2. Delete old emails: Encourage the user to delete old emails to free up space in their mailbox. You can also use the qmail command-line tool to delete old emails programmatically.
3. Use a larger mailbox: If the user needs more storage space, consider increasing the mailbox size. You can do this by editing the qmail.conf or qmail-smtpd.conf file and increasing the mailbox_size value.
4. Use a quota management tool: Consider using a quota management tool like quota or qmail-quota to manage user quotas and notify users when they're approaching their limits.
5. Check for spam or viruses: If the user's mailbox is being filled with spam or viruses, consider using a spam filtering solution like SpamAssassin or ClamAV to help clean up the mailbox.

Remember to restart the qmail service after making any changes to the configuration files.
