ok, i did a sentech install for a client of ours yesterday, and i noticed something seriously stuffed up...

It wont allow them to use there external smtp servers...

ie: if there email is [email protected], it wont allow them to use smtp.doggiestyle.com

OK, granted I got it to work with smtp.sentechsa.com But this thing is painfully slow, and I would prefer to use external smtp servers.

How on earth do I get this right, of does sentech not allow external smtp servers to be used?

Actually most external ISP's will probably not allow your MySmokeSignal IP's to send mail via SMTP directly. We're classified as dial-up users and as such SPAM generators ;-)

The only method is to use sentech's SMTP (as you have) or have your own SMTP server that you use.

Direct delivery worked in the EARLY days of the service before we got added to the DUN user groups ;-)

Try secure authentication.

MySmokeSignal, hahaha

i'm the gingerbread man!
 
I have installed on both smtp.absamail.co.za and smtp.intekom.co.za. Both worked, although absa has recently forced the use of secure authentication. pop3.absamail.co.za and pop3.intekom.co.za work flawlessly, and this is whether using dial-up from either of those two networks, or via MySmokeSignal.

It works if the smtp address is related to the account.

Example: [email protected] will work with pop.billybob.co.za but wont work with mail.hostingcompany.co.za or smtp.hostingcompany.co.za

Briantw: We talking smtp's not pop's pop's will work flawlessly since its incoming mail (POP), but with outgoing mail(SMTP), if the email address isnt related to the smtp server address, sentech wont allow u to email out.

SMTP servers use an IP range in order to determine if it should relay an email or not. An open relay is normally blacklisted by anti spam lists such as spamhaus if the offending isp does nothing about it. All South African 1st tier isps have closed thier smtp servers for this very reason. Some 2nd tier isps offer smtp servers that use authentication to try allow cross network smtp traffic, but this means that their local bandwidth gets chewed up and they normally close them once there is a large traffic volume.
 
Which brings us back to the fact that we are forced to use smtp.sentechsa.com which is slow, its quicker to print the email, drive from Pretoria to Cape Town and delivery it yourself.

No you are not. Access control based on IP is one method available (it is the most common).
Many ISP/Host's (mostly second tier) offer other methods such as SMTPAUTH, and POP-Before-SMTP.
It just depends on how your mail admin configured the server
