Can't send any emails since Friday

B1ngham — Mon, 14 Jul 2025 16:00:01 GMT

Hi everyone,

I've used a force 9 email address since the late 90s without a problem, but since Friday I can'r send emails except via webmail. I can receive emails without any problems. Whenever I try and send an email I get the message "Cannot connect the the account xxxx, enter the password for user xxxx" on Outlook Express, and on Gmail "credentials needed, please enter credentials for xxxx". However my username and password work fine on webmail and I have altered no email settings.

Any ideas what I should do next bearing in mind I'm relatively computer illiterate?

I have exactly the same problem. Have you managed to resolve it yet? I would appreciate any advise that you can give.

Unfortunately not. Also doesn't send emails on Mac mail as well. My settings are unchanged and my log in and password works fine on force 9 webmail.

Can you each please run the email server connectivity diagnostics - see the link below.

Of particular note...

Are you on or off the Plusnet network#
What credentials are you using as the UserID
Is the mailbox encountering the issue of the form a.b@ (rather than ab@)

MylesT — Tue, 15 Jul 2025 09:47:26 GMT

yes I am off the plusnet network (i.e. isp is not plusnet).

I am using both info@ and joe.blogs@

I am receiving email, but can not send.

Sorry for being think but I could not find where the email serve diagnostics is?

Last link in my signature ... but I am confused ... you are using it on the other thread discussing POP3 connectivity issues!!

Off network, I expect info@ to work, but suspect @joe.blogs will not - I did a sanity check this morning, but have not yet raised to the business as I need 3 examples to dive attention.

Re: Can't send any emails since Friday

MylesT — Tue, 15 Jul 2025 09:55:31 GMT

No other threads

No info@ does not send any emais and joe.blogs@ does not send any. Both receive.

This thread here - https://community.plus.net/t5/Email/eMail-mailbox-cannot-send-force9/m-p/2013666#M50861 - also to do with SENDING but reporting connectivity issues on the inbound POP3, having used the diagnostics.

It does not help posting on the same issue on multiple threads ... or is someone else using your forum ID as well as you?

I will ask the mods to check and merge your posts into a single topic.

Can you each please run the email server connectivity diagnostics - see the link below. - run, had this from kernel

"A002 BAD Mate, try LOGIN <username> <passwd>

* Closing connection

* TLSv1.2 (OUT), TLS alert, close notify (256):

curl: (67) Login denied

Enter host password for user"

Of particular note...

Are you on or off the Plusnet network# - off the network,
What credentials are you using as the UserID - I've tried using both my user id and email in the format xx@userid.f9.co.uk to log in
Is the mailbox encountering the issue of the form a.b@ (rather than ab@) - I'm not sure what this means

Re: Can't send any emails since Friday

MylesT — Tue, 15 Jul 2025 17:32:50 GMT

Sorry, I am not able to run the email server connectivity diagnostics, as the Microsoft OS Windows I am using is old (WIndows 7 Pro) and does not have a terminal window facility.

That’s unfortunate!

B1ngham — Tue, 15 Jul 2025 21:21:16 GMT

My terminal outcome as posted above or MylesT's inability to run terminal?

@B1ngham

Sorry about that - I missed your post!

That looks like a fundamental issue running cURL. Looks like a non-standard environment ... might need some help from @Dan_the_Van

a.b

email addresses can have have any of a-z. 0-9 ".", "-", "_" in them, such as...

joebloggs@
joe-bloggs@
joe_blogs@
joe.blogs@

There is a specific issue under investigation for the last email address variant when connecting to the SMTP server from an off Plusnet network connection for a Force9 user.

Email address authentication will work for the DEFAULT email mailbox, but currently not for a secondary mailbox, that must use account+mailbox

@B1ngham @MylesT

Can you please confirm the operating systems you are using?

Re: Can't send any emails since Friday

B1ngham — Wed, 16 Jul 2025 07:23:36 GMT

Mac Os15.5. Android 14 on my phone. Current os on iPad. None of them will send emails.

Thanks,

for the cURL test you drop the .exe from the text string and just use curl -v

Is this what you are doing?

You have confirmed the setting to be the following in the email clients?

IMAP: imap.force9.net port: 993 TLS/SSL
POP3: mail.force9.net port: 995 TLS/SSL
SMTP: relay.force9.net port: 587 STARTTL

Yes It has a dos/cmd window but curl is not installed so it does not run the commands

Which is what selecting OTHER for the PLATOFRM does for user.

The key question not answered relates to the mailbox name, specifically is it a.b and is the connection coming off network?

If both are true than as of the status yesterday, one is not going to get a SMTP connection using the secondary mailbox credentials. One is going to need the default mailbox credential for the SMTP server. Not an ideal work around whilst the issue is resolved.

@MylesT

If windows 7 pro then I do not believe curl would be part of the software build.

Seems to be added with Window 10

EDIT: curl can be downloaded from here https://curl.se/windows/
