Postfix is denying sending mail to a handful of users
I've got a strange problem here:
I connect via IMAP to my mailserver (which is also my rootserver). On
this server Postfix is delivering the mail.
If I send the mail to 5 users it works perfectly.
If I send the mail to 20 users (BCC), postfix does this with the mail
Jul 10 18:58:32 xxx postfix/smtpd: NOQUEUE: reject: RCPT from
xxx.t-ipconnect.de[xxx]: 554 <xxx>: Relay access denied; from=<xxx>
to=<xxx> proto=ESMTP helo=<xxx>
Has anyone an idea why this does happen?
I've already raised the limit:
~# postconf -d | grep smtpd_recipient_limit
smtpd_recipient_limit = 1000
but it seems that it does not work.
Has anyone of you an idea?
