I know we've had some mail problems recently which i thought had been resolved but this morning im getting SMTP timeouts when trying to send
Im receiving mail ok and dont know whether its related to the recent troubles so is anyone else seeing this at all ?

Hi Bill,
I've managed to successfully telnet to our outgoing mail server.
Can you try rebooting your computer abd trying again?  I take it that incoming mail is fine?

Hi James
Thanks mate your help is always much appreciated
Ive just found out what the problem is and its not on your side, my outgoing mail goes through a proxy this is where the trouble is 
thanks again and sorry to take up your time
cheers
Bill.
