isp blocked all outbound port 25. so i unable to send mail using my private linux mail server. is there any workaround . from what i know, sendmail server always use port 25 to communicate with other smtp server. is it possible to change the port to other port?
my laptop --- port25---> my private linux smtp server --- ? ---> outside world smtp server
p/s: can the "?" change to other port ?
i know there any service like mailhop offered by no.ip ..etc.. there is no other workaround ? what if i install other smtp server other than sendmail ?
