Problems associated sending email from Club sites

Pilgrim21

Has anyone experienced problems sending email using the Club wifi system?  I can receive email without a problem using Windows Mail but not send.  Investigation within the 'Help' area of the progrmme indicates that the problem is probably due to an incorrect
outgoing mail address, the smtp address.  If that is the case do I need to change to smtp.airangel.co.uk or something similar?  (I think airangel are the suppliers of the Club wifi system.)  I do not want to work online with my usual ISP's website as it means
duplicating my address book, etc and having effectively two address books will undoubtedly lead to errors.
