Are you living in Singapore, using M1 and wants to set up an email client into your mobile phone? I’ve looked thru the M1 website, and they never did mention their M1 SMTP server. If you’re seeing this page, then you must have been Googling, like me.. lol..
I gave M1 a call and here it is: smtp.miworld.com.sg
If you are using custom services, for example, you got a domain package from Global Domains International where you have your own domain like http://nazayakob.com and custom email addresses like email@example.com, you must use this M1 SMTP Server to set up because GDI don’t provide outgoing SMTP server.
