New phone problems

Please help a tech dunce 
I've got a new Samsung Galaxy A3 and have just set it up so I can receive my emails from my webmail account. The emails come in no problem but I can't send anything - the outgoing emails are just sitting in the outbox. I've rejigged the sync settings to the most frequent, but nothing is happening.
No similar problems with texts.
An ideas folks?

Failing that you need to check the settings for the outgoing server. smtp.somethingorother.co...

Check the webmail provider and see if they list the info somewhere. Then, check you phone/tablet for the account you have added to see if there is an option to define the send element (should be in the same kind of area that you set the receive bit).
It will either be the outgoing port or something you have ticked that shouldn't be or vice versa. You might find checking what is ticked somewhere else where it is working the fastest way forwards. Once you have it keep a record of what works.
Also, I found with one of the galaxies that the order settings are changed made a difference - with one of them reverting to a previous value unless it was the last value changed.
Someone explain to me how progress means making things harder.
I am on three and have a plusnet email and previously had to use the plusnet incoming SMTP server but the three outgoing SMTP server. There is now another plusnet outgoing server that seems to work or they changed their settings.
Its probably a case of using another outgoing SMTP server.

it would have exactly the same issue, as does os x mail
pop, imap, smtp etc. are old protocols from days before the internet was invaded by criminal gangs, spammers, script kiddies and other sadfucks
so they've had various bags strapped to them to try and improve security, but there are many options and not all client/server implementations support them all, service providers must also choose parameters, some choose different ones
with so many clients/platforms and their developers 'enhancing the user experience' by hiding or attempting to automate set-up parameters, the user is left wondering if the latest software update/device model is faulty or if it's simply wrong set-up because the 'improvemed' version now requires different configuration to the old version, this is exacerbated by email service providers failing to keep their instructions up to date for the new releases
as a result it can sometimes be painful
