[nos-bbs] New 2.0j.3 Winlink smtp feature

[Michael E. Fox - N6MEF]

Gus, 

I think I understand the point you're trying to make.  But, if so, it is simply false.

1)  Winlink has no ability to place address format "requirements" on JNOS or any other SMTP MTA.  SMTP address formats are defined by IETF RFC, not the Winlink organization.
2)  Sending a message from an SMTP MTA addressed to "callsign at winlink.org" works just fine.
3)  Sending a message from an SMTP MTA addressed to "smtp:callsign at winlink.org" fails because "smtp:callsign at winlink.org" is not a valid SMTP address.

So saying we "have to use it" (i.e. that JNOS has to add "smtp:" before Winlink addresses) is simply false.  And because Winlink is not the IETF, it will always be false.

The "smtp:" prefix *may* be used by Winlink clients to designate that the email goes out to the SMTP world.  But, again, that's is for messges from Winlink *TO* SMTP, as the prefix suggests.  JNOS is the REVERSE direction:  from SMTP, *TO* Winlink.  So even if JNOS needs some way to initiate a different set of handling rules when sending to Winlink, the prefix "smtp:" would not be right.

But even Winlink doesn't "require" the use of the "smtp:" prefix.  I sent messages using Outpost connected to the CMS with telnet and they worked with and without the "smtp:" prefix.  So, it's evidently not even a requirement for Winlink clients!

Winlink DOES impose a subject line restriction (must start with "//WL2K") but that has nothing to do with the address.

Perhaps to move this forward, I'll ask this question:
What EXACTLY does JNOS do differently if I address a message as "smtp:user at domain" vs. just "user at domain"?

my intention was far to be offending or for any other odd purposes.

However, the 'SMTP:' prefix *is not* an invention for JNOS2 but it is a strict *requirement* of the WinLink 2000 project, so, since (thanks to Maiko) the JNOS2 become, with version 2.0j.3, *fully
compliant* to WL2K we *have to use it* with no exception.

To summarize: the actual JNOS2 features on the WL2K environment are:

sending and receiving emails (inbound and outbound) 'to' and 'from'
<callsign at winlink.org>  (i.e. i0ojj at winlink.org)

or 

sending and receiving emails (inbound and outbound) 'to' and 'from'
any commercial email addresses; i.e. to send an email to me, just type on the address:

SMTP:g.ponza at tin.it

on the the contrary: if you send an email from your commercial address to my WL2K address just type on your mailer:

i0ojj at winlink.org

and, on the subject put the prefix '//WL2K' as:

//WL2K this is my email subject...


that's all
