named or numerical IP addresses better for Exchange?

sent this out before and help still needed......

Have set up EntourageX with Exchange5.5.
Problems I have encountered are:
1. I have found that the process will only work with the use of
numerical IP addresses (eg. 172.221.20....) for IMAP, LDAP and SMTP
but not for named addresses (eg. SSHMAIL03). Using named addresses
gives "connection failure". Changing back over to numerical addresses
gives access, although then only to SMTP/sending mail. (see problem
2). Why??

2. I can send email but can't read email. An error message of "invalid
Account ID or password" comes back. This can't be correct because when
I then shut down EntourageX and revert to Outlook 2001 with the same
ID and password it logs on without any problems.

Any thoughts/solutions please?
