Hi all,
I have setup dovecot 1.1.4 and sendmail 8.14.3 with dovecot LDA on linux (RHEL5 on x86_64).
I have deliberately set a very low quota (4MB) on a test account, while the actual disk usage is 5MB at the moment, in order to test overquota behaviour..
When I send an email to this account, sendmail accepts the email and tries to deliver it. Deliver fails to save in INBOX and returns an error, but the email stays in sendmail's queue..
Any suggestions on how to avoid this and produce a 5xx error for overquota users before accepting the email would be greatly appreciated..
TIA, Sotiris.
