#231045 — debian exim4 smarthost and relay

I hope this is the correct group for debian exim4 questions.  I'm sure
someone will point me elsewhere if not

 - Setup: New install of debian 10, in VBox vm attempting to get exim4
   working.
 - Internet host with no recognized or dns resolvable name, or domain
 - Receives dhcp address, but made mostly permanent by router
   capabilities

When editing a smarthost line in udpate-exim4.conf.conf
How does one enter a server that requires ssl 465.

Is adding 465 port all that is necessary? ..like

     dc_smarthost='smtp.server.com:465'

I've also seen two colons used while googling on this:

    dc_smarthost='smtp.server.com::465'

Which if any is correct?

-------       -------       ---=---       -------       -------

If one uses the port number in update-exim4.conf.conf is it also
required in passwd.client?

   smtp.server.com:465:user@some.domain:SECRETpw

And again .. one or two colons? Or is this not required?

-------       -------       ---=---       -------       -------
My googling has also caused some confusion to me about
editing something for smtp transport:

Will it also be necessary to edit something into smtp transport
regarding the use of ssl 465?  If so, can anyone show an example of
how that is done?

Two colons—dpkg-reconfigure exim4-config should tell you that, thus:

 ┌───────────────────────┤ Mail Server configuration ├───────────────────────┐  
 │ Please enter the IP address or the host name of a mail server that this   │  
 │ system should use as outgoing smarthost. If the smarthost only accepts    │  
 │ your mail on a port different from TCP/25, append two colons and the      │  
 │ port number (for example smarthost.example::587 or                        │  
 │ 192.168.254.254::2525). Colons in IPv6 addresses need to be doubled.      │

Not required. I presume a password applies per site rather than per port.

I'm not sure what specific location you mean by smtp transport.
I've used various ports at times, 25, 465, 587, and aliases for 25,
but all made in those two files mentioned.

Cheers,
David.

	Hi.

dc_smarthost="your-smarthost::465"

See update-exim4.conf(8).

No, because passwd.client is interpreted as colon-separated triplet.
String above will be interpreted as "465" as username and
"user@some.domain:SECRETpw" as a password.

No, not in Debian. Debian's exim should use TLS for mail exchange
without any configuration providing that your smarthost advertises it.

Advertising TLS on your MTA - that does require some configuration
indeed - exim4_exim_crt(5), but that's redundant in your setup.

Thanks to all for the succinct and helpful answers

Sometimes googling excessively can confuse me a bit.

For 99% of installations:

  dpkg-reconfigure exim4-comfig

as root.
