I do not receive notification mails

esmirQ
Hi,

I get the following smtp.logs:
R=dnslookup defer (-1): lowest numbered MX record points to local host
retry timeout exceeded
SMTP error from remote mail server after initial connection: host deadmail.fw-notify.net [93.189.156.232]: 421 Too many concurrent SMTP connections; please try again later. 
do-not-reply@fw-notify.net R=dnslookup T=remote_smtp defer (0): SMTP error from remote mail server after initial connection: host deadmail.fw-notify.net [93.189.156.232]: 421 Too many concurrent SMTP connections.

    Hi, esmirQ,

    When did this start happening?  Try making a new backup and then restoring a configuration backup from before the problem started.

    Did that work?  If not, restore from the new backup and let us know.

    Cheers - Bob

    Hi,

    This issue starts since my mailserver was up and running (dmz) which is also the receiver for the notifications. Eg. If I try to send notifications to different mailservers it works fine. I also double-checkt if my mailserver reject the notifications but he doesn't! Is it possible that my dmz configuration (snat, dnat, etc) is the reason for this issue?
