Greenby emails not working - Receive YES - Send NO

[#1]

Since migrating to Greenby I can no longer send emails - receiving is ok.

This has affected both my email client on my system using Windows 7 Pro and my mobile phone.

I was successfully using Outlook Express email client for many years with Plusnet - up until the migration.just before Christmas this year.

My mobile: Galaxy J3 (2017) was also working fine for sending and receiving - now receive ONLY.

Also, since migrating I have received about 500 Spam Emails!!! Why is Greenby so leaky in this repect?

Plusnet should take us all back and Charge us for their email service! That would solve all the problems since migrating.

@Sam8 Exactly what are all the settings you are using for the outgoing SMTP servers? They should include server name, port number, security and authentication settings. It is possible they could be non-standard that worked with PN but not greenby.

Can you also try sending an email from webmail?

Here's my complete setup for OE client and mobile phone with Plusnet - both worked before Christmas this year 2025 until Greenby migration - and both setups given to me when I joined Plusnet years ago. I have been back and forth with Greenby support for past five days to no avail. YES, sending and receiving in Greenby Webmail is ok.

The message received from just looking at the foregoing on the mobile without changing anything said: "Unable to connect to email server to verify your account information. No response from server"

Thank you for offering to help, Sam

Forgot to say - with OE I am in an authentication loop, as when I try to send an email I get a diolog box which says: -

'Please enter your username and password'

I enter the correct information, but it just goes round and round in a loop asking the same questions - 10 times, 20 times, for ever!

Tried again on my mobile and this time got a message: -

"The username or password is incorrect or POP3/IMAP access isn't turned on for this account, Check your email account settings on the web, then try again"

@Sam8 the problem with most email clients is that they are not good at returning information as to the 'real' error, rather they just assume a username/password error.

Can you try the emil diagnostics , particularly the smtp test from here https://community.plus.net/t5/Email/Diagnosing-email-server-connectivity-issues-the-guide/m-p/200795...

That should report the real reason for the non-sending

Incredible stuff MisterW, but I didn't understand a word of it.

I am a senior over 75 and everything worked PERFECTLY before the migration, really smooth for many years, then Plusnet dumped us for emails - why? I would have been happy to have paid for Plusnet email - how did it all work in Plusnet, but not in Greenby? What have Greenby done that is so different to Plusnet? Plusnet told me the migration would be seemless, but for so many it hasn't been seemless at all?

@Sam8 Looking at your mobile settings for SMTP, I think that

Security Type: None
Port: 587

are wrong. Port 587 is correct, but is for encrypted emails, so Security should be set to StartTLS ... but it may appear as just TLS on your phone - different email programs use different terms, which makes it confusing!

The fact that webmail can send emails shows that there is nothing intrinsically wrong with your Greenby account - the problems are with your email programs.
