Im guessing you have the SMTP proxy enabled? I don't use it myself. On the SMTP page, theres an Advanced tab with many options like reject non-FQDN sender, and reject non-FQDN recipient. Do you think those settings are interfering?
Also in Advanced settings, theres an IMAP server for SMTP authentication. Is that what you enabled? IMAP works differently... I recently switched a customer from SBS 2000 to SBS 2003, and external clients had to enable Secure password authentication (SPA) to get it working for them. This is controlled by options on the SMTP virtual server in Exchange. Before that, passwords were sent in clear text. I have port 2525 forwarded to port 25 on the server for external users, only because I have a linux box filtering spam and viruses for the Exchange server. 2525 is needed to bypass the spam box, because port 25 is forwarded to it, which then sends processed mail to port 25 on the exchange box. I other words, the spam box sits in front of the Exchange box. Otherwise, I'd only need to forward port 25 to the server, because everything happens on that port. -----Original Message----- From: Ifan Jones [mailto:i...@anheddau.co.uk] Sent: Monday, December 15, 2008 5:53 AM To: efw-user@lists.sourceforge.net Subject: [Efw-user] Relaying email from outside source Hi All My setup INTERNET - EFW/MODEM - GREEN - LANSWITCH I would like external users to relay email through - authentication has been enabled on th einternal mailserver. I have tried this two ways Method 1. Proxy - SMTP - Advanced settings Enabled this feature and inserted my internal mailserver's IP address, whilst trying to send from outside, you can see the login ok on the internal mailserver, but when it gets to EFW - I get SASL Authentication failed Method 2. Reading up on what others have done - I chose a random port, let's say 12525, and forwarded it to the internal mailserver, now on the external clients - I setup this port for the SMTP server and switched on authentication - delivering email to internal addresses works juts fine, but on outbound, I get a relay access denied on EFW - any tips?
