RAQ550 : Relaying Denied
My Raq550 suddenly started not sending mails from some domains, it says : 550 5.7.1 <user1@aol.com>... Relaying denied. IP name lookup failed [68.16.80.34]
RCPT TO: user11@aol.com
451 4.3.0 Temporary failure
RCPT TO: me@another.net
450 4.7.1 me@another.net... Relaying temporarily denied. Cannot resolve PTR record for 61.11.23.131
The weire thing is that some domains are affected by this while others are working just fine, dunno whats causing this.
Any suggestion will be appreciated.
Thank you,
