[Dovecot] quota-warning.sh not working (lda problem?)

[Thomas Krause]

For testing I replaced

/usr/local/libexec/dovecot/dovecot-lda -d $USER with
/usr/sbin/sendmail $USER in the quota-warning.sh script. Now
the mail is delivered when 80% or 95% of quota is reached.
Any idea, why dovecot-lda doesn't deliver the warning mail?

Regards,
Thomas.
