Exchange 2007 mobile phone email no longer can relay mail.
Posted on 2009-07-09
Mail can be received to phone however sending generates MAILER-DAEMON failure.
Barracuda SPAM firewall generates the following:
#< #5.0.0 X-Spam-&-Virus-Firewall; host xxx.xxx.xxx.xxx[xxx.xxx.xxx.xxx] said: 522.214.171.124 Unable to relay (in reply to RCPT TO command)> #SMTP#
I'm wondering if there may have been a certificate failure or my send connectors are not configured properly.
The phone was able to send a while ago. Nothing other than Windows updates were applied to the server.
Used an iPhone to test the account with the same results either POP3 or IMAP4.
In an attempt to resolve this issue I've installed SP1 to the Exchange 2007 last week.
