Today, a friend of mine called me and questioned me why she can’t send emails using her mail client which is Incredimail which is one cool mail client because of the effects and animation.  It really bothered me a lot because I can’t solve the problem without being there in the situation and it is hard to explain things using a phone. So I went over to her place and to find out that PLDT changed their SMTP port to 587 which is not the usual port of SMTP.  But this is not only the solution, outgoing mail server should also be changed to smtpdsl4.pldtdsl.net instead of using your own outgoing mail server(mail.icpep.org).

This has become an issue but still PLDT has no action for this.  This is really one problem especially to those people who are not that techie.  Hope PLDT will change it back to the usual port and find other ways on how to solve the spamming issues.

To summarize it, you can configure your mail clients using the following information:

Outgoing mail server SMTP: smtpdsl4.pldtdsl.net

UNCHECK – My outgoing server (SMTP) requires authentication

USE Port: 587

Hope this helps in solving your problem.
