Does Dtac Have An Smtp Server For Outbound Messages?

[smallbear]

I have been a DTAC customer for some years and successfully send SMTP mail to various servers anywhere using port 25 or 587, but since purchasing another Internet package last week (and an Android phone to go with it also), I haven't been able to send any SMTP. It just remains in the outbox, and yet I can successfully use 'verify server' to ensure that I get an authenticated login to it.

I know that TOT (for example) blocks other SMTP servers and one has to use its own, but until this new package, I have never experienced the problem with DTAC.

I called customer services at DTAC today and the chap asked me to go all the way to Siam Parragon to the smart phone specialist shop (200km away 555). Totally unrealistic, just to find out if DTAC has an SMTP server I can use.

Note: My smartphone sends SMTP mail when I'm connected to my home Wireless-LAN, so therefore I know that it is the DTAC mobile data that is stopping it from working.

Any ideas?

I'm not sure if this is the answer to your question, but I use my iPhone's personal hotspot to send mail from my computer and I use smtp1.dtacnetwork.co.th, "no authentication, default ports 25, 465, 587".

Many thanks Fredlk, this has helped me to make further progress. I was inspired by your idea of using the phone as a means of connection for a computer (although in my case I used USB) and as a result of that, I successfully proved that the DTAC connection itself does not prevent the SMTP from being used, because it allowed my PC to send using two other e-mail clients.

It is therefore the software in the Android phone that is preventing the mail from being sent. I found that DTAC allows other SMTP services to be used quite happily, although the SMTP1.DTACNETWORK.CO.TH works equally well. I was unable to use SSL port 465, or the alternative port 587. But port 25 was fine.

I'll have to concentrate on solving the problem with the phone, but at least I now know where the problem lies. Many thanks.

Just to follow-up on this. I have fixed the problem. It was caused because the e-mail client in Android requires that the security certificate be viewed and accepted, even though there isn't a certificate on my server.
