My Virgin broadband email account refuses to send.
My machine is an Apple Imac with the latest greatest operating system and all the updates. (mountain lion)
I have an Australian Virginbroadband account and the emails had been working totally trouble free for a number of months, then without any reason my system decided that it will not send an email.
I receive emails without a problem.
I can browse the internet without problem.
the apple email connection doctor can make connection to both the inward and outward email servers whenever I fire it off without any errors.
my apple system just will not send an email.
I have checked that all the account details are still correct (they worked for 6 months error free)
I have run a rebuild on each mailbox. (inbox, flagged,outbox, sent)
I have checked that my machine's time is correct.
I have had one test email in the outbox now for 2 months. it was generated as a reply to an email I received. it is a minimal thing with no attachments.
Checking with Virgin, my system is using the correct ports.
there are no account quotas that have been exceeded.
the configuration details are still in the valid format.
the servers are working properly and other users can send emails without problems.
from what I can see everything in my machine is correctly configured and there are no error messages that I can see.
all is correct except that it doesnt work.
when I have ceased internet use I disconnect from my provider. close all windows and then send the machine to sleep.
I have cold booted the machine from a power off.
when I check configurations I find nothing corrupted or missing.
the only thing I havent found in my system is the actual log trace of the outward mail attempt.
can anyone put their finger on what the **** the problem is.
