access email from a diffirent provider

Hello guys,
just want to know why some of the user of my coova network is having a problem with sending email.
can somebody drop a little info.
thanks

You can specify any SMTP

You can specify any SMTP server and the iptables rule will be created for you.

HS_SMTP=yoursmtpserver

I would use the SMTP server of your ISP as any other server is likely to require authentication. If it doesn't, then it is likely that it will be blacklisted for spamming.

thanks

thanks for the response....
i will check this one out...
anyway about the smtp server.. i have a email server which is functional..
how can i give my coova gateway to use my smtp server with access. and if so, how can i define or assign username and password for my coova gateway to connect with my smtp server.

thanks

work around solution....

let's everyone on your network be able to send mail, no matter what SMTP server their mail program is set up to use
with this iptables rule
