Change to smtp.verizon.com from outgoing.verizon.com - sendmail configuration

[nigelhorne]

What is the configuration needed for sendmail?  I'm running under Ubuntu 13.04.  Setting up the smart_host stuff and authorization is easy, but I can't remember how to force sendmail to connect to port 465.

Look at this page http://verizon.com/emailsettings

As far as where these settings go in email under Ubuntu, I have no idea.

Thanks, but those tell you the values to set which I know.  What I can't firgure out is how to get sendmail to work.

I've added this to sendmail.mc:

define(`SMART_HOST', `smtp.verizon.net')dnl
define(`RELAY_MAILER_ARGS', `TCP $h 465')dnl
define(`ESMTP_MAILER_ARGS', `TCP $h 465')dnl

But when I try to drain the queue I get this:

Running /var/spool/mqueue/r82D31IG002661 (sequence 1 of 18)
{edited for privacy}@verizon.net... Connecting to smtp.verizon.net. port 465 via relay...
{edited for privacy}@verizon.net... Deferred: Connection reset by smtp.verizon.net.

Nigel, Disclaimer: I was rated 1/10 on a scale for Linux skills, but I did find this http://www.moundalexis.com/tm/2010/10/28/getting-past-verizons-residential-smtp-block-with-sendmail/

Thanks for the pointer.  In fact I'd found that before I posted on here.  However it relates to the old outgoing.verizon.net, not the new smtp.verizon.net.  In particular it doesn't solve the port 465 problem where I can't connect to it even using telnet.

I believe that I have it fixed and can now use Sendmail to send mail out again.

The pointer is at http://www.dawoodfall.net/index.php/relaying-sendmail-a-ssl which shows where Virgin Media in the UK pulled the same stunt as Verizon.  It doesn't quite work as mentioned, you need to put the relay domain in square brackets to avoid MX resolution, however apart from that it's sweet.  I didn't set up relay-domain as mentioned.

Briefly, to enable using sendmail to deliver mail on FIOS:

1) install stunnel

2) Create /etc/stunnel/smtp.verizon.net.conf with:

sslVersion = SSLv3

[ req ]
client = yes
accept = 2525
connect = smtp.verizon.net:465

3) /etc/init.d/stunnel restart

4) Add sendmail.mc:

define(`SMART_HOST', `[localhost]')dnl
define(`RELAY_MAILER_ARGS', `TCP $h 2525')dnl
define(`ESMTP_MAILER_ARGS', `TCP $h 2525')dnl

5) Add to authinfo:

AuthInfo:fqdn.of.your.localhost "U:name" "P:password" "M:PLAIN"

AuthInfo:fqdn.of.your.localhost:2525 "U:name" "P:password" "M:PLAIN"

6) cd /etc/mail && make && /etc/init.d/sendmail reload

And it's done.  Easy when you know how!
