GNUs email multiple outgoing accounts from the same server without imap

I use GNUs and multiple email addresses, including changing the outgoing SMTP based on the FROM on the message. SO far so good. Now, though, I have multiple accounts on the same server, so the usual .authinfo doesn't work for me. It seems like the answer should be similar to http://www.cataclysmicmutation.com/2010/11/multiple-gmail-accounts-in-gnus/ but I am NOT using gmail, and I am NOT using imap. I am using SMTP and SSL. How can I extend that solution? (Also: I am using gnus-posting-styles to help send mail with the appropriate address, for what that's worth)

Below are the relevant parts of my .gnus. Note that I am trying to get the webdev@[ME].com working, which is in addition to [ME]@[ME].com (both the same server). What do I need in here, and in my authinfo, to make this work?

    ((header "cc" "[ME]@gmail.com")
         (address "[ME]@gmail.com"))))

SOLUTION

The answer I was looking for came below. For completeness, I'm posting what my end-result solution looked like using my /etc/host file, .authinfo, and .gnus.

;; excerpt from .gnus
(defvar smtp-accounts
  '(
    (ssl "[email protected]" "mail.onedomain.com"
     26 "[email protected]" secret)
    (ssl "[email protected]" "mail.onedomain2.com" ;; <-- This is the new alias in my /etc/hosts
         26 "[email protected]" secret) ;; <-- Added these two lines
    ))

;; excerpt from .authinfo
machine mail.onedomain.com login [email protected] port 26 password MyPASS
machine mail.onedomain2.com login [email protected] port 26 password "MyOtherPASS"

;; excerpt from /etc/hosts. The IP was obtained by pinging my mail.onedomain.com
69.89.31.60 mail.onedomain2.com onedomain2

The X-Message-SMTP-Method header field for message-mode might help as well.

Example:

X-Message-SMTP-Method: smtp smtp.fsf.org 587 other-user

I have a similar set-up, where I use posting-styles in gnus to choose between several email accounts. I used to do it as mentioned, defining different aliases for the same host, having authinfo entries. It looked like this:

Contents of ~/.authinfo.gpg:
machine imap.gmail-alias1.com login [email protected] password pass port 993
machine imap.gmail-alias2.com login [email protected] password pass port 993
machine smtp.gmail1.com login [email protected] port 587 password
machine smtp.gmail2.com login [email protected] port 587 password

Partial contents of /etc/hosts:
# So I can use multiple gmail accounts in authinfo
# should be same address as imap.gmail.com
173.194.70.108 imap.gmail-alias1.com
173.194.70.108 imap.gmail-alias2.com

74.125.136.108 smtp.gmail1.com
74.125.136.108 smtp.gmail2.com

BUT I switched to using postfix to send the mail. What you can do is set postfix up so that it can (for example) receive mail for [email protected], [email protected], [email protected] and send all messages to smtp.gmail.com, while using appropriate account credentials in each case. This requires you to install the Postfix program, and set up the files */etc/postfix/sasl_passwd* and */etc/postfix/sender_relay*.
