Free-online migration: unable to send emails

[#1]

Hi, I'm being migrated to Greenby and now cannot send emails either on Free-online or on Greenby. I don't think my ISP likes their use of port 25 for outgoing mail, but now I can't even send by webmail. I get told I'm 'unidentified sender'. Any advice, please?

[#2]

First off (not that I think it will make a difference) port 25 has never been the correct port for email client message submission.  That should be done on port 587.

Port 25 is for MTA to MTA message relay.

Migration: being as in you’ve been scheduled or been as you’ve received a welcome to Greenby email?

What sending email address are you using?  That of a real mailbox or an alias?

Are you on the Plusnet network?

Is this just in a mail client or webmail too? 

Do you have outbound auth set if you're not on the PN network ?

I am reading this with interest as I too have recently been notified that I am about to be migrated to Greenby shortly and have my Outlook email account settings set to:

Incoming (POP3) = Port 110             Encryption tick box (SSL) = blank

Outgoing (SMTP) = Port 25               Encryption tick box (SSL) = blank

I am a legacy Freenetname user (if that is relevant) who was migrated via Brightview->Madasafish->Plusnet over the years and, as far as I can recall, have always used these settings.

If it is relevant, I use a myname@freenetname.co.uk style email address, and another which uses my Freenetname supplied domain name  myname@myowndomain.co.uk style address. I have never used myname@myaccount.plus.com directly and have never used webmail.

To limit possible causes of any potential email issues, I have been deliberately trying to avoid making system changes of any kind until the move to Greenby has been completed and proved to be working OK, but should I be changing any of these particular port settings prior to the migration?

That brand is not yet in the migration programme.

What brings you to tag onto this Free Online thread which IS in the migration programme?

If you have a specific issue, the mods can be requested to spilt your post off into its own thread.

It's the fact that I've already received an email from Plusnet advising me that my email service is to be migrated to Greenby on the 24th November, and I noticed that your earlier response here mentioned that Port 25 was not the one that should be used for outgoing messages - which is what mine has always been set to.

I was reading it that the Port 25 setting comment applied to email sending generally, rather than to a specific email brand (e.g. Free Online) and as I am highly dependent on my email service, I am concerned if this port setting could cause a problem when the migration occurs.

[#7]

In principle it should not be a problem.  It is though always better to adhere to the recognised standards.

In an ideal world no one should be using port 25 (or 465) for email message submission.

Am still having problems – now unable to receive or send emails whether using Apple Mail or Outlook. I give up. Will just have to use it as webmail.

You did not respond to key questions.  The sender details are of concern as indicated the error message you reported in the first post.

I'm using the sending email address the same as the incoming, which is my main email address: [user]@[domain].free-online.co.uk

Am on free-online.

I've always used a POP account, so am puzzled they told me to use imap.free-online.net as incoming address.

Outgoing is relay.free-online.net

Apols for not responding earlier. I can only post when I'm not at work, and also am getting v stressed about this: am autistic and getting on in years.

[#11]

It matters not, they point to the same server in Greenby land.

[#12]

Thanks, because that was puzzling me.

[#13]

I've tried some alternative port numbers from their support page, but they're not saving, and also I'm still being told username and password aren't verified. Whole thing has me stumped. Am waiting for another response to my ticket with them.

My parents are sill having problems with their migrated "free-online" email account.  The whole migration really hasn't gone very smoothly.

NOTE: They have never received the "Welcome to Greenby" email (as email failed completely) so we're kinda flying blind here.

After quite a lot of effort a plusnet support agent was able to get their greenby account working and them logged into it.  From there they are now able to see incoming emails on webmail (via greenby.com not webmail.greenby.com).  

However, they say they are unable to send emails through webmail - it bounces back saying unable to send.  

I've been on the phone to my parents a lot talking it through, and this seems to be that Gmail are refusing the emails sent to gmail.com addresses: "550-5.7.26 Your email has been blocked because the sender is unauthenticated."  

If mail sent from the Greenby webmail interface is failing authentication I assume this is a server-side problem (again I believe this is via greenby.com not webmail.greenby.com).  It's clearly not to do with how a local mail client is collecting the mail.

Anyone else seeing this?  Any of the mods or plusnet staff able to give Greenby a poke?

[#15]

You need to offer clearer descriptions of the issue.

Can email not be sent at all or is it just a matter that Gmail is not accepting delivery?

There is a massive difference between not being able to send (as per the title) and the belligerence of Gmail refusing to accept delivery if successfully sent email.

Sending via webmail will be authenticated.  Sending via your own email client might not have authentication set on the outbound server.

More details are required from Gmail’s belligerent refusal to accept delivery.  The NDR details should indicate their excuse for rejecting delivery.
