Hi, I recently installed a new SBS 2011 Server migrated from an SBS 2003 etc.
Everything is fine apart from their Line of Business Database program isn't sending out their emails but email sends out fine as normal for Outlook etc.
I don't have much information on the database apart from the fact it points to the internal IP Address of the SBS server and uses port 25 and runs on their workstations with the data actually running live across their network but is actually held on the SBS Server.
I've advised the customer bulk email sending isn't really recommended via Exchange server these days because of spamming / potential blacklisting etc as I believe the database uses their internal Exchange Server to send out several thousand emails but it always worked before on their old SBS 2003.
I've tried setting up a new “New Receive Connector” within Exchange Console under Server Configuration and Hub Transport.
Gone to "Receive mail from from remote servers that have these IP Addresses.
and put in their internal DHCP scope range that their client PC's use i.e. 192.168.x.10 - 192.168.x.200
Gone to authentication and ticked "TLS" and "basic authentication"
then permission groups and ticked "anonymous access"
Got them to try from a client PC sending again but all the database says is "socket error"
it's quite an old and outdated bit of software and isn't very configurable in terms of it's SMTP settings.
Would appreciate if anyone has any ideas on this or if there is something I might be missing??
Many Thanks in advance.
