Why are my outgoing emails not being delivered?

[Anonymous]

Hi

I am having problems with email messages sent from my mobiler not being delivered to the recipient.

I use Kcom (formerly Eclpise) for my email.

My incoming mail works fine.

For my outgoing email I use the O2 server as advised (smpt.o2.co.uk)

Emails that I send to a btinternet.co.uk or to an hotmail account appear to send ok but never get delivered.

Is this a known problem and is there a solution (other than have to send using a different email account)

Thanks

Each of your email addresses needs to use the smtp server for the respective email provider.
You can no longer use o2's smtp server I'm afraid.

As o2 shut down there servers you need to use another server for your outgoing emails

Like this for Kcom:

Incoming IMAP mail server	imap.karoo.co.uk	Port 143
Outgoing mail server	smtp.karoo.co.uk	Port 25
Incoming SSL	No
Outgoing SSL	No
Login ID or Username	Your full KCOM email address
Password	Your KCOM password

Hi

When I try those settings i get the message

server does not support authentication.

As per the instructions above, Auth should be off, no or blank

Solved but not resolved.

KCom/Eclpise Customer support finally gave a proper reply instead of passing the buck to O2.

"I can appreciate the frustration - the issue you are facing is one that is well documented but is also integral to the security of the mailbox for legacy service options such as the mailbox associated with your connection.
Although we still support this service option it is not one that is available to new customers - In fact we do not offer any new residential service options anymore.

If you use any other email service you can always use their outgoing mail server instead."

They are only interested in business users not residential users.

In this case, use your BT smpt server settings and BT log in.
It doesn't matter which server you use to send via as long as your emails are coming in OK you will not see any difference.
