My domain alias seems to have stopped working

[#1]

Last week martin@domain.co.uk worked. This week it does not seem to. I am awaiting a email re' undelivered goods. I have sent an email from my hotmail A/C to above it did not arrive. If I send to mjtuohy@domain.co.uk (my original domain choice) It arrives. What has changed ? or am I just being thick.

Hi there,
There are a number of emails waiting to be collected in the martin mailbox. Remember that when you are collecting from a specific mailbox the login details you need to use are username+mailboxname along with the specific password for that mailbox.

I don't understand. Last week when I opened Thunderbird all my emails downloaded automatically. Are you saying this does'not happen anymore ?

If you haven't made any changes then you should still be receiving emails to the same mailboxes as before. It would be worthwhile checking the settings in Thunderbird and making sure you have it set up to collect from username+martin

Thank's so much that last idea worked got lots of replys now. I have been getting more and more angry with this company about my order and all the replies were on the server. Time to eat humble pie me thinks
