I have just changed service my provider from Orange to 3.
My email provider is 1and1.

Both IMAP and SMTP worked ok with Orange.
SMTP fails with 3 (all i did was change service provider)

Solution 3 ban port 25
set your SMTP port to 587

I have the same problem with a 1&1 smtp server and 3 network. Did you use SSL or TLS for your smtp connection on port 587?

I can't get it to work on any combination.

Thanks

sorry for the dealay but with my email provider 1and1 security is set to none

not sure if this is the problem - but relaying SMTP (outgoing mail) through 1 and 1 on the 3g signal will not work.

you have to have the po settings for your incoming as teh 1 and 1 settings and the SMTP set to 3s own smtp settings.

pop comes in smtp goes out (sorry if you already know this)

You will however be able to send via wi-fi on 1 and ones smtp settings but not 3g.

Port 26 is another option for SMTP.

Just seen this post and thanks for the info on the ports! I have been having tremendous trouble with three trying to get my outbound email to work when I am away from home. My ISP has been telling me it needs to be three's smtp server and three keep telling me it needs to be my ISP's. They are completely and absolutely incompetent and clueless and none of them can speak fluent english or understand what you are telling them, either that or they just don't listen to their customers. I will give these other ports a try but I am not too confident that they will work.

hi another option

is to sign up for a free mailjet account

this will relay your emails via secure system and you dont need to change your mail id either

thats what i did as moved from o2 to 3 and hit the same issue

hope that helps
