Hi Ron,
If you're using sendmail, you probably want to use the smarthost feature
to have it send all mail via your email provider. So if your smarthost
provider is smtp.comcast.net, you would modify sendmail.mc and before
the MAILER definition you would add something like:
define(`SMART_HOST', `smtp:smtp.comcast.net')
Then run "make" which should convert the sendmail.mc into sendmail.cf.
If that's successful, restart sendmail, then try sending some messages
to see what happens in mail.log.
I use Debian at home too (Debian 10 actually), but I use postfix there.
In that case, you would edit main.cf and set the default_transport line
to be:
default_transport = smtp:smtp.comcast.net
Note that some of your providers may (probably will) require you to use
SMTP authentication and STARTTLS to be able to send mail ... That will
require additional configuration.
For Sendmail,
http://www.sendmail.org/~ca/email/auth.html
and look for "Using sendmail as a client with auth"
For Postfix: http://www.postfix.org/SASL_README.html#client_sasl
Hope this is helpful.

Hi folks,
Tell me if posting question like this is out of bounds. I’m still
relatively new to Linux—but I’m managing my own servers. I’m running
Debian 9 and working in PHP. The application I’m working on needs to
be able to send emails. PHP requires an MTA to be installed for its
/mail()/ function to work. I’ve installed SendMail, but I’m getting
lost in what documentation I have found for configuration.
I’m wondering what people are using for an MTA and how you are solving
the problem of mail servers junking your emails (because they don’t
trust the source). My thought here is to use one of my email
providers (Comcast, GoDaddy, or Gmail) for the SMTP service. But that
means configuring the MTA to do that.
Any advice would be appreciated.
Thanks in advance,
