I am testing ver 5.01 and found a strange problem.
If I enable "Require AUTH" I can not anymore sne messages to user@mms.domain.com, it needs SMTP AUTH which doesn't make sens for global internet use. If I disable this feature then anyone can send +number@sms.domain.com without SMTP authentication which is very insecure, pluse doesn't allow any kind of billing. I believe the AUTH setup should not be global and should always be required for buld SMS sending and should be optional for SMTP->MMS sending.
Please advise

Hi Wojtek,

I'm sorry, but I don't understand your question.

Correct. This setting is performing as it is supposed to. It is for use in environments where only properly configured clients connecting with SMTP AUTH can submit messages.

That is not normal behaviour. Did you edit MMSC.INI to add an "SmtpIPAddressList=" parameter? That is the only explanation that I could see for this type of behaviour. (See http://support.nowsms.com/discus/messages/1/460.html for a description of that parameter.)

Let me explain how the SMTP AUTH logic should work.

1.) If "SMTPIPAddressList" setting is present, any messages from the specified IP addresses will be accepted without requiring any AUTH.

2.) If "Require AUTH" is checked, then excepting #1 above, no messages will be accepted unless the client authenticates with SMTP AUTH.

3.) If "Require AUTH" is not checked, then messages will be accepted for alias@mms/sms.domain.name or phonenumber@mms/sms.domain.name, where the "alias" or "phonenumber" is defined in the "MMSC Users" list.

4.) Excepting any of the above conditions, any messages addressed to phonenumber@mms/sms.domain.name, where phonenumber is not associated with a user defined in the "MMSC Users" list will not be accepted without SMTP AUTH.

I understand now.
SO, in summary; Under normal circumstances one would not use SMTP AUTH if want to provide MMS-SMTP gateway, but if smtp->sms is required then IP range should be limited.
Am I correct?
Thanks,

Hi Wotjek,

It depends on what you're trying to accomplish. The limited IP range does seem to work best for most users.
