[SOLVED]Re: Outlook 2010 problem

[Jayanta Ghosh]

Dear List, Our problem has been solved by doing the following :- a. The package cyrus-sasl-ntlm-2.1.22-4 was installed in our server. As a result of which NTLM authentication was enabled in our server. You can test this by executing telnet IP ADD of server 25. You will be able to see the following lines upon giving EHLO  250-AUTH CRAM-MD5 PLAIN LOGIN NTLM GSSAPI DIGEST-MD5 250-AUTH=CRAM-MD5 PLAIN LOGIN NTLM GSSAPI DIGEST-MD5 b. To disable NTLM auth we have added one line "mech_list: PLAIN LOGIN" in the file  /usr/lib/sasl2/smtpd.conf. After this the above Auth mechanism will be changed to 250-AUTH LOGIN PLAIN 250-AUTH=LOGIN PLAIN After this just enable the setting "My outgoing Server (SMTP) requires authentication" and followed by the login credentials would enable you to send emails to the outside domain from Outlook 2010. I would like to thank you all for giving us your valuable suggestions. Bye...

Depending on your client_access file maybe even before this one. Maybe try this one. I think you should also post client_access and sender_access file. Is authentication for sending enabled in the clients MUA? Regards, Claus --
