So I now know it is no encryption, as you said above, and can test the options for Authentication Method, one by one, which are five in number. Is it worthwhile?
I think I see what you're trying to do. Here is a telnet conversation I had with my ISP:
Code:
telnet> open -l eyo -a pop.sonic.net 110
Trying 69.12.218.40...
Connected to pop.sonic.net.
Escape character is '^]'.
+OK Dovecot ready.

There I am just testing unencrypted authentication, that my username and password actually work. http://www.ibiblio.org/ais/siberia.htm
So combining what you and Alien Bob already posted, I'd try telnet with:
Code:
open -l estefan34@telecentro.com.ar -a pop.telecentro.com.ar 110
I'm not sure if the @ symbol needs escaping, but it's easy to try. Maybe you don't need the whole string in the username. I was remembering a similar issue when Earthlink bought Mindspring, and all logins were changed to include the domain. That was fun .

This is what I get for what it's worth.
Everything seems OK. Just give it a try with Thunderbird as Rob suggested. Either you type your username wrong or Seamonkey mangles it.
Outgoing settings: smtp.telecentro.com.ar does not use encription [sic]. What do you think? What I personally think is it would be great to have a simple setup procedure and the syntax to use sendmail, as I intended to do in post #1.
Anyway, I kept trying with Thunderbird, correcting the parameters found by him, but it behaves exactly like Seamonkey did.
Unless that's a typo, you're entering the wrong Username:ESTEFAN34. Try the one that worked with telnet "estefan34@telecentro.com.ar"

Okay, I'm out with that comment because I don't know sendmail or any ISP that will allow unauthorized connections on port 25 anymore, explained here: https://wiki.sonic.net/wiki/Port_25
If you want to try Tbird's manual configuration use mail.telecentro.com.ar on port 587 with correct username and password. Good luck!
You're right, a typo it was. The typo corrected, the situation remains the same as with Seamonkey, which really uses the same routines from Thunderbird, as I could see, for the setup.

This is busybox sendmail output (help). I think I adjusted to this syntax in the command above. Do you find a fault. If you don't, could I use telnet too?
I hope Eric won't take offense at my departure from GUI methods! [smile]I remain open to suggestions, be it GUI or CLI. I found this too: http://etutorials.org/Linux+systems/...sing+sendmail/ but is Redhat focused.
Then I opened my yahoo.com mail box and found the three lines, rather unbelievable! As sendmail is used to deliver mail, according to the manual, I haven't the faintest idea how I can read mail sent to me using an analog mechanism.
sendmail succeeds in transmitting but no files in var/pool/mail after reply.
Hi: I've been successful in sending mail to yahoo.com with sendmail. So, the second part of my job is being able to see answers back in /var/pool/mail. What I did: in yahoo I replyed with some text. Then I look in said dir and see a file with zero length and the same time as that I replyed at.
One question is: why zero length.
On the other hand, if I use the mail command to have a nicely formated file to send I receive nothing at yahoo and usuing 'mail' at the prompt gets 'No mail for user_name', where user_name is my username. So lets forget about 'mail' for the time being and restric our attention to sendmail. Having seen that it succeeds in sending from text typed at the console to yahoo, how could I do to get something, in a systematic way, in /var/pool/mail?
If you ask for the format of the sendmail command used I can send it, as well as the setup used.
I, from my yahoo mail box, reply to the sender, I do not not see the reply in /var/spool/mail, save for this:
Code:
estefan34@telecentro:~/Desktop$ ls -l /var/spool/mail
total 20
-rw-rw---- 1 bill mail 0 2014-06-05 03:14 bill
-rw-rw---- 1 estefan34 mail 0 2014-10-25 00:24 bull
-rw-rw---- 1 estefan34 mail 0 2014-10-25 00:41 estefan34
-rw-rw---- 1 pepito mail 0 2014-06-11 13:56 pepito
-rw-rw---- 1 root root 18617 2014-10-25 01:01 root
estefan34@telecentro:~/Desktop$
Why have these files zero length?
Why wouldn't you use fetchmail which is designed specifically for this (receiving mail from an upstream POP3/IMAP server)? For easy IMAP there is also offlineimap. sendmail is one of the most complex pieces of software included with Slackware and if you're not actually running a mail server, fetchmail is a much better solution.
sendmail is complex because it is used by MUAs and MTAs for SMTP transport. Now look at the manual: not over 500 lines. Look at fetchmail manual: almost 3000 lines. For the user sendmail is easier, because, besides, slackware does all of the configuration work for him.
If you know sendmail, why don't you give me a syntax equivalent to that of busybox sendmail, which is this?:
Code:
BusyBox v1.21.1 (2013-07-08 10:44:30 CDT) multi-call binary.
Usage: sendmail [OPTIONS] [RECIPIENT_EMAIL]...
Read email from stdin and send it
Standard options:
-t Read additional recipients from message body
-f SENDER Sender (required)
-o OPTIONS Various options. -oi implied, others are ignored
-i -oi synonym. implied and ignored
Busybox specific options:
-v Verbose
-w SECS Network timeout
-H 'PROG ARGS' Run connection helper
Examples:
-H 'exec openssl s_client -quiet -tls1 -starttls smtp

-H 'exec openssl s_client -quiet -tls1
-connect smtp.gmail.com:465' <email.txt
