Port 587 seems to be open on smtp.eclipse.co.uk

Are you setting your mail clients up as IMAP rather than POP?

Thinking about it I'm sure the problems I used to experience  went away long before I changed to hosted email. I used plus nets email servers from around 2003 to early last year, and when I first got a tablet had problems. It may have been when I changed to IMAP that the issue went away, sorry but can't remember the details.

Well the last time I asked my ISP Eclipse (Business) they said it would not work away from home but I have not tried it recently.
mail.eclipse.co.uk port 110 for receiving mail.
smtp.eclipse.co.uk port 25 for sending it.
You really shouldn't be using insecure ports for email these days. Try using ports 995 for receiving POP3 (or 993 if you prefer IMAP) and 465 for SMTP both with SSL/TLS encryption ticked. You may find that those ports also require authentication and will work away from home.

Hi

I am sorry, standard ports 25 and 110 can be insecure or secure using StartTLS (see below for standard SMTP test using port 25)

If anyone is using our platforms, you will be on haveworx.co.uk and to avoid any SSL error on email, we always advise to use mail.haveworx.co.uk for incoming/outgoing servers for all services, and leave as default ports in client software (port 465 is usually not used any longer and SMTP ports are 25 and 587 - some may still allow 465 though)  We use SMTP 25 and 587 only on this platform.

If anyone is wondering why I have left/quoted full domain/IP, it is a live platform and has been scrapped many times, so no need to hide.

@tickmike, I would email your ISP support for full clarification, as most allow connections from any networks as we do and you would be advised not to use any mail relay services.

Many thanks

John

Hi

I am sorry, standard ports 25 and 110 can be insecure or secure using StartTLS (see below for standard SMTP test using port 25)



Yes, can be, but not all servers support StartTLS whereas if ports 465 and 995 are accessible they will be secure as far as I'm aware.

Hi

Yes your correct

However, for client software/servers not to support StartTLS means they would be old (years old)

However, as you correctly state, ports 465 (if still in use), 587, 993 and 995 would be set to SSL/TLS only (note SSL is still shown but should not be available and only TLS is used - this no doubt would be updated to reflect TLS only in time as software is updated)

I think I read a few years ago that mail ports were trying to just use 2 standard ports, but I do not believe that would happen

Many thanks

John

The OP is asking about SMTP (i.e. outgoing mail). IMAP/POP3 is therefore irrelevant as that is only how mail is collected!

Warning - while you were typing 2 new replies have been posted. You may wish to review your post.

Thanks for trying to help. :)

While waiting for the post man to come I have set up on an old spare laptop that has never had mail set up before.
ThunderBird is the email client.

setting mail.eclipse.co.uk port 995 SSL/TLS  Normal password, This works ok and downloaded mail.
But.
using  smtp.eclipse.co.uk  port 25 works ok, port 587 SSL/TLS  Normal password Does Not work (times out)
and the same with port 465 .

I have opened ports on my hardware firewall for the above.

Edit... Pop
Ok I will check out that screen shot later.

Hi

@Tickmike - to be honest, I would not bother looking/checking the picture.

I have just tested using smtp.eclipse.co.uk and smtp.karoo.co.uk on port 25, and both confirm 554 not allowed - you can quickly test this yourself from a command prompt

telnet smtp.eclispe.co.uk 25

if a 220 response shown type

rset

quit

You should receive a 220 response whereas not been on Kcom network, our response was 554 not allowed disconnected

Interestingly, running a test on eclipse.co.uk shows the following (note no secure ports) see below

So I am thinking you are correct and it is locked to Kcom network only but sorry if I am wrong, and I would email Kcom support for full clarification

Many thanks

John

How bizarre, presumably they don't expect their customers to want to access email from their mobiles other than via webmail!

PS @tickmike There is no need to open any ports on your firewall, you are originating the connection.

I thank you for trying to help  :), I did change my incoming server from 110 to 995 ..

I have sent Eclipse an email to ask them about the subject.

I had a reply from Eclipse .

Legacy E-mail
Incoming POP3 server:   mail.eclipse.co.uk  Port:110
Incoming IMAP server:   mail.eclipse.co.uk  Port:143
Outgoing SMTP server:   smtp.eclipse.co.uk Port:   25
Incoming SSL: No
Outgoing SSL: No
Login or Username: Your full ECLIPSE email address
Password: Your ECLIPSE password
Webmail:   http://webmail.eclipse.net.uk   

If you're using a different connection, change SMT outgoing server into what the ISP you're using has.

Not very helpful  :'(
