Topic: Using POP3 for External users

[bas60]

I have a problem getting EXTERNAL users to use POP3

MX record set for domain

so for both incoming and outgoing the mail server settings in pop3 is set mail.mydomain.com

Incoming works fine but with outgoing I'm getting a message
System Administrator message "550 Relaying denied for user@domain.com"


-------------------------
I have also tried (non secure pop3)
db configuration setprop pop3 access public
signal-event email-update
-------------------------

Any help appreciated

The problem suggest a problem with your SMTP..

Do you have two domains that have the same name?, that is one on your SMESERVER and one in the internet world?

[bas60]

emm....I have just one domain setup in domains

mydomain.local and mydomain.co.uk

maydomain.local resolves locally and mydomain.co.uk Internet

I can delete the mydomain.co.uk but NOT the mydomain.local

[shawnbishop]

I think that may be your problem, remove it and see if it works

[bas60]

I thought I needed the mydomain.co.uk otherwise if the 1st bit of the domain is enough - am I not at the risk potentially flooding with emails to mydomain.com, mydomain.co.uk, mydomain.eu and the rest!

Unfortunatly the system has just gone live since last thursday - everything works except external users with pop.

If I remove the mydomain.co.uk - would that not stop incoming emails??

At the external location you need to set your local ISP's outgoing mail server in your email client.
By default, relaying is not supported when connecting to your sme smtp server via another ISP's connection.


If you want to send via the sme server smtp server, enable secure smtp in server manager and configure the appropriate ports in your email client.

ISP (BT) won't allow use of their mail server if not connected to them!
and its not practical when users are travelling.

Using 7.4 - there is an option SSMTP - this seems to be ENABLED by default

Can I use the default port 25 or do I have to open 465 on the router?

I assume existing LAN users can carry on using 25

you have to forward port 465 TCP to your SME to permit ssmtp for external users

yes
