A queue runner will try it again in a while, after a period defined by the *retry* configuration section of your Exim config file. See the chapter on *Retry configuration* in the Specification: http://www.exim.org/exim-html-current/doc/html/spec_html/ch-retry_configuration.html If a queue runner starts and checks the message but the period the message has to wait before a retry is attempted hasn't yet passed then the queue runner skips that message. Likewise if you try doing a manual queue run using the "-q", "-R" or "-S" options to Exim. See the chapter on *The Exim command line* in the Specification: http://www.exim.org/exim-html-current/doc/html/spec_html/ch-the_exim_command_line.html (It can also be helpful to search the net for the error you're seeing, such as exim "retry time not reached for any host" which can quickly lead you to a posts from others who have seen and solved the problem.)

The reason text given seems to suggest that either your end or theirs is requiring the SMTP connection be encrypted using TLS, but that the other server didn't offer TLS. (I suspect it's your server complaining about the mobiletomaildomain server: you might have your Exim configured to require a TLS encrypted connection to the far server but it's not offering STARTTLS to you.) As Jeremy says, it's difficult to say for sure as you've obfuscated and mangled the log line so much; doing so really doesn't help us to help you!
