If your email program is not listed above or is a different / older version you 'may' still be able to use AuthSMTP - please contact us for more information.
Note 1: Entourage 2001 for Mac is compatible (needs to be version 9.0.4 or later).
Note 2:
- Exchange 2007 has been tested and can be used with AuthSMTP but you need to be aware that you need to consider the issue regarding SSL/TLS in Exchange 2007 as it requires action in any case
- Exchange 2003 has been tested and can be used with AuthSMTP
- Exchange 2000 should also be compatible - however, we have not fully tested it in-house
Note 3: Pocket Outlook is compatible - it requires your AuthSMTP user name and password to be changed to the same as your POP3 username and password - see Can I change my user name and password? for further details.
