Problem sending email

[#1]

For Greenby the Username needs to be the email address of the mailbox : <name>@<account>.plus.com

Greenby usually does not use the old Username format : <account>+<name> & I would avoid an alias too.


The out bound email server aka the SMTP server in the configuration as this thread started contained relay.plus.net

Try replacing relay.plus.net with mail.enmail.co

Just reading the plusnet faq about the email changes and migration

https://www.plus.net/help/email-account-changes/

The What do I need to do? section is the key bit.

To send email we recommend that you enable authentication for outbound email.
For customers with a Plusnet, Force9 or Free-Online email address you should use your main mailbox username and password in the outbound settings.
For Callnetuk, Care4free, Dialstart, Freenetname, Globalnet, IC24, ICScotland, Madasafish, Totalserve or Totalise and Metronet you should use your email address

So, does that mean for Plusnet, Force9 or Free-Online to send from an email client all mailboxes and aliases should all use main mailbox username and password for the outbound settings?

E.g. for email addresss beginning name1@username and name2@username instead of username+name1 or username+name2 as outbound settings both would now use just username and its password as the outbound settings?

[#3]

@njay Enabling authentication is done at the base level of your account. i.e on your outgoing server settings tab on your mail program. Do you use a client program, or just webmail?

@jab1

I use both

In plusnet webmail i can login to each mailbox independantly with username+name1, username+name2, etc each with their own password

On client i can do the same, as whilst incoming and outgoing settings can be independantly set, currently they are set the same alebit with different ports/encryption

What i was referring to is that the details provided on plusnet migration faq changes that to all mailboxes using just main username and password as outgoing settings

The credentials for outgoing can be any valid set i.e a mailbox set or the main account set, they dont have to match the incoming ones. That's always been the case. 

[#6]

I read 'authentication' as setting the ability to send when not on the PN network, obviously we are not 'on the same page'.

@MisterW

I thought that may be the case for plusnet

On greenby its suggesting it can only be the main account set for outgoing and in prep for that the plusnet migration faq is saying to set it that way.

Might explain why people with plusnet, force9 who have migrated are finding they cant send emails from mailboxes other than the main one as their outgoing is still configured as username+name?

The details also list a difference as only thise 3 brands require outgoing with username whereas all the other brands state using actual email address.

I am puzzled as to why email configuration presents so much confusion and why folks go to such convolutions.
What you can do with SMTP and what you should so have become very blurred in some posts.

For example, it is not a good idea to use a different set of credentials for the SMTP server, because
when the owner of the other email a/c changes their password, your email sending will stop working
and worse each time your laptop or mobile re-retries it will be racking up the failed login count.

Greenby have improved the security of the SMTP service, their next step may well be to impose sending for a given email address requires authentication using the credentials of that email address.This is an effective way to reduce sending of faked emails.


We do this ...

We have 7x Plusnet email in the format : <name>@<account>.plus.com

In each case the POP3 or IMAP Username is the email address of the mail box ( not <account>+<name> & not an alias )

For the SMTP server the same credentials are used, in MS Outlook just tick use same credentials, on mobile apps etc you may have to enter the details again for the out going mail server.

All 7 email accounts migrated from Plusnet to Greenby and  worked without adjustments.

it is only the recent months that we have had persistent false spam rejections from relay.plus.net causing lock outs and cascades of password changed, if faced with this relay.plus.net can be replaced with mail.enmail.co or relay.force9.net this specifically for *.plus.com email accounts that have  migrated to Greenby.


Use encryption ...

Using an encrypted connection is a very prudent idea & often enforced by Microsoft & Gmail.
All Plusnet and Greenby email servers use the industry standard ports.

POP3S via Port 995 with SSL / SSL/TLS encryption
IMAPS via Port 993 with SSL / SSL/TLS encryption

STARTTLS via Port 587 with TLS / STARTTLS encryption
SMTPS via Port 465 with SSL/TLS encryption

I agree with you and i am not confused at all

I currently use username+name and password where name and password is unique for each mailbox as that was perfectly valid for plusnet for well over a decade. However a unique email address for outgoing per mailbox (note a mailbox is not a one to one mapping to an email address especially for those who use aliases) for settings is fine with me too

However, please read what the plusnet migration text says. It specifically says for plusnet, force9 and freeonline to use username of main account for all outgoing email settings not the unique email address you would expect

The rest of the brands state to use email address so why these 3 are singled out is the thing i am intrigued (not confused ) about as clearly it works if you use the email address with these ones too.

I've been busy this morning so only just been able to get back to getting a solution to the problem I started this topic for. Is it my imagination or has the topic moved away from that. 

Here is an update to my problem:-

My wife's laptop can receive emails but cannot send them. My own pc had a similar problem a few weeks back. If my unreliable memory serves me well, my pc problem was solved by MisterW, who got me to go into my Thunderbird, select "Tools/Account Settings", click on Outgoing Server (SMTP), and then Edit where I had to change “relay.plus.net” to “mail.plusnet.enmail.co”. I then had to use my Thunderbird(?) password to be able to send emails. There was a minor problem that the next time I entered Thunderbird and tried to send an email, I had to use my password again. To get round that he suggested I checked "Use Password Manager To Store Password". From that point on my emails have rarely been a problem.

The trouble with my wife’s laptop is she uses Windows Live Mail, and she doesn’t know her password. Apart from that, Windows Live Mail doesn’t seem to show up on her laptop like Thunderbird does on my pc, so I have not been able to go into it in the same way as I did with Thunderbird. Are any of you knowledgeable on Windows Live Mail? If so perhaps you could tell me what I have to do to get this thing working again.

Thanks very much. Regards to all

those 3 brands are the only ones to use subdomains and allow multiple mailboxes e.g mailbox@<accountname>.plus.com. the others use mailbox@emaildomin e.g  mailbox@madasafish.com

I am aware of the suggestions to use <account> and <account password> for the SMTP server, if memory serves we only had this format as a bit of a kludge in the early 2000s when mobile phones started to have data and email apps.  We had POP3 credentials but lacked the SMTP credentials for 3G phones when out of the house.

But 20+ years on email boxes all have both inbound  and out bound credentials so I prefer to use them. If you are using an alias, it still has an underlying mailbox to provide the credentials.

Another SMTP nugget, for migrated account holders.  If a new email box is created in the Greenby portal it only gets SMTP credentials for mail.enmail.co and relay.plus.net both of these have good security certificates for sending via STARTTLS or SMTPS.

How do I get into Windows Live Mail so that I can change the SMTP setting?

[#14]

Use the desktop icon or task bar icon or from the Start Menu.

How was Windows Live Mail started to enable the capture of the error message in the 1st post ?

[#15]

Like me, my wife uses Mailwasher, so her laptop is set up that when she has gone into Mailwasher, and clicks on the "Process Mail" button it puts her into Windows Live Mail. I haven't found an icon for Windows Live Mail - at least not yet. As a last desperate attempt to get her email working both ways, I suppose I could install Thunderbird on her pc, then adjust Mailwasher as necessary. Quite what would happen to all the emails she has received up until now, I dont know. Are they safely on her pc? If they aren't, she may not appreciate losing them.
