I recently applied the Sun patches to my RaQ4 and some customers are reporting an inability to send email. This is a typical message from the maillog file:
May 24 15:19:27 www sendmail: h4OKJR326181: ruleset=check_rcpt, arg1=<Brad.Robinson@mcsinet.com>, relay=adsl-67-116-7-48.dsl.snfc21.pacbell.net [67.116.7
.48], reject=550 5.7.1 <Brad.Robinson@mcsinet.com>... Relaying denied
I know that this is not a case of POP-before-SMTP, but rather it has something to do with the "ruleset=check_rcpt".
I am able to email the same recipient from my email account on the same server, but different domain. Any ideas?
