[Typo3] E-mail service on typo3

[Arjuna]

Hi,
I have succesfully installed typo3 on my server and all seems to work
fine apart from mail service. I explain the situation:

- typo3 installed on one server (new.domain.tld)
- the old typo3 server is domain.tld (a different server)
- the mail server is on another server
- the mails sent to info at domain.tld from typo3 of new.domain.tld did not arrived

the mail service of typo3 works fine only for external domains (i.e. a
mail sent to user at gmail.com delivers correctly).
Any idea on how to resolve?
Thanks
Arjuna Del Toso
