Need some help getting s-nail to work with comcast [solved]

I am trying to get s-nail to work with my ISP which is comcast but when I try to send a test message from the shell, I get

% mailx -s test myname@comcast.net < /dev/null
mail: Variable is read-only: #
mail: Variable is read-only: #
mail: SMTP: Resource temporarily unavailable
mail: Unexpected EOF on SMTP connection
/home/mike/mail/dead.mbox 9/209
mail: ... message not sent

Following the wiki example, I made this as ~/.mailrc where the first bit comes from the package /etc/ version and the last part I took from the wiki.  My actual password is hidden with xxxx below.

set autocollapse
set append
set ask
set crt
set editheaders
set emptystart
set fullnames
set history-gabby history-gabby-persist
set hold
set indentprefix="> "
set markanswered
set mime-counter-evidence=0b1111
set keep
set keepsave
set quote
set recipients-in-cc
set sendcharsets=utf-8,iso-8859-1
set showto
retain from_ date from to cc subject message-id mail-followup-to reply-to


set v15-compat
set ssl-protocol=-ALL,+TLSv1.2
set ssl-verify=strict
set reply-in-same-charset
set fullnames
set sendwait
set mimetypes-load-control
set folder=mail
set MBOX=+mbox.mbox record=+sent.mbox DEAD=+dead.mbox
set inbox=+system.mbox
shortcut mymbo %:+mbox.mbox \
         myrec +sent.mbox
set from="myname@comcast.net"
set mta=smtp://myname%40comcast.net:xxxx@smtp.comcast.net:465 \
    smtp-use-starttls

It looks like you're not reaching the server at all, or it's rejecting your connection. Are you sure smtp.comcast.net:465 is the right server & port combination you're supposed to use? Is that host accepting smtps request for TLSv1.2 only? Check your ISP documentation and make sure you are using the protocol they support.

465 is smtps, but also try smtp and port 587 (it's open and the interwebz™ says it's the preferred protocol for comcast)

Thanks go to you seth. It is working now using port 587.

set ssl-protocol=-ALL,+TLSv1.2
set ssl-verify=strict

I believe that s-nail 14.9.16 deprecated these options.  See the man page of mailx for some examples, but this should work for you:

set tls-config-pairs'\
 CipherString=TLSv1.2:!aNULL:!eNULL:@STRENGTH,\
 Curves=P-521:P-384:P-256,\
 Protocol=-ALL\,+TLSv1.1 \, +TLSv1.2\, +TLSv1.3'

Re: Need some help getting s-nail to work with comcast [solved]

It seems smtp.comcast.net supports SMTPS at port 465.  It does not seem to support TLSv1.3 yet, but the following should work (and smtp-use-starttls can be removed at :465, not at :587):

  set tls-config-pairs=MinProtocol=TLSv1.2
  set mta=smtps://myname%40comcast.net:xxxx@smtp.comcast.net:465

No 1.3 yet (xv is a function which locally sets verbose, as shown under COMMANDS in the manual):
