I have been using the Mozilla Thunderbird email client for about two weeks (at least until the time when I was writing this article) from a previously using Eudora email client. Along with this, I was moving in terms of media usage than the old Internet connection (using IM2) to become using the Smart Telecom Indonesia.
Everything goes smoothly, starting from the process of importing all emails in the old email client to the new email client: Mozilla Thunderbird. Similarly, for checking or receiving emails; everything goes smoothly. Until once upon a time, I found something that quite annoying my activities: cannot send email out using that mail client! I totally can not send mail using the SMTP mail server setting that belongs to any email accounts I already had, except for by using Gmail account. Hey, what’s wrong with this situation?
I don’t know what the cause, but clearly, this has happened since I moved to the media of and Internet connection using EVDO modem Smart. After asking Google, finally I found the solutions to overcome this, is by changing original SMTP, from using the SMTP setting of each mail server that belongs to the email account that I use, to become now just use one SMTP settings, namely:
The SMTP Port is still the standard used: 25 (for general SMTP), whereas for the send authentication, this setting does not need it at all (No authentication). In addition, I also don’t need to set explicitly the Username (not specified), nor the Connection Security (None).
I am not sure whether this solution also passed on the Smart Telecom belongs to the countries other than Indonesia. So, please try it by yourself, if you are currently using the Smart Telecom Internet connection and are facing the same problem as I described above.
