taking the information from your other posting of this thread you were using the sendmail binary to send the message. This leads to using the submission mechanism (that's ok and standard).
The MSP accepted your message - thus the "queued mail for delivery" log note - and tried to send it out using the MTA daemon part of your sendmail installation.
Until this is successful the message is kept queued in /var/spool/clientmqueue, to be queried by
mailq -Ac
Thanks very much for your useful posting. The mail is arriving now without delay, so the problem must just have been that my remote ISP did not like me giving a local address.
