OUTGONG SMPT for emails on wifi disabled

For the past few months I cannot send emails from my cell phone on my home wifi, I can only receive. All other apps etc work on wifi. VODACOM - WHAT HAVE YOU DONE? <br> I am not alone in this! Vodashop employees shrug their shoulders. They know all about this and the complaints are starting to build up! Telling me I should change my outgoing smpt each time I switch from wifi to data is NOT a solution! That is madness! For 4 years everything worked via my home wifi. Then not. This is nothing to do with my cell phone or my wifi service provider - this is a VODACOM thing.<br> I have only experienced this problem when overseas logged into hotel wifi where some restrictions may have been installed. <br> VODACOM you have shut down a port or something to force use of data for outgoing emails. This is not user friendly and whatever you have done - this is incredibly frustrating and unfair. Please undo it!
