Is there a way of having B9 activated when the mail server has no domain name? A <ip address>.b9 syntax doesn't work.

Yeah, I'd like to know what's up with that, too!

When I installed Benign, one of my accounts pointed to the IP address of a local machine on my LAN, which is my host for YahooPops.

The address was:
192.168.100.1


The import function converted the address in my Eudora.INI to:
b9.192.168.100.1.b9


and put the following into my HOSTS file:
127.98.9.3 b9.192.168.100.1.b9


However, it doesn't seem to fly.

I haven't tinkered with it to get it to work yet, 'cause YahooPops is kinda not ready for prime time yet - and it was just a toy, anyway ... but what is the proper form for ip addresses?

I suppose I should have posted the resolution I found. Actually it looks like you were close Roger. Yes the host file can be used to assign an alphanumeric hostname to an IP address but don't tag the .B9 extension in the host file. Rather put something like
Code:
192.168.100.1                     YahooPops
in your hosts file. If you use the host name I suggested and if the syntax required is in the form <host name>.B9, put
YahooPops.b9
in your Eudora.INI file.

Why do you need it? If the mail server has a domain name you can use that and tag it with B9 as follows:
Code:
<mail_server_domain_name>.B9

Use this as the entry for the incoming mail server at your email client if you want to activate B9 parsing.

That said, if you really do need the IP address for any reason, just perform an nslookup of the machine's domain name.

There may be a little hitch for clients that do not allow a different smtp name than pop. In a single direction proxy, this presents a problem with these clients that only use the pop address as it will attempt to use the same address for the smtp.

For example in the case of mailserver.com.b9, smtp would fail when trying to be accessed with the account of mailserver.com.b9 instead of simply mailserver.com.

I don't follow that. As I understand it, B9 would intercept the mailserver.com.B9 address and request the messages at mailserver.com. I.e. it shouldn't matter if the incoming server address = the outgoing server address.

It depends on how the mail client. In the case of your pop address being mymail.com Benign will add the .b9 to it. This allows its association via the Windows host file to find the Benign proxy. In Outlook you would have mymail.com.b9 listed for your Pop server, and mymail.com listed for your SMTP server. All is good in Outlook at this point.

However there are other clients that will simply pass the name for the Pop server to the SMTP side of the tracks, and what they will pass in this case is mymail.com.b9 which will not be recognized by the SMTP server, you can receive all the mail you want, you just can't send any out.

This is a common proxy setup problem. Most of these client do have ways around this, either in the registry or their equivalent ini types of files, unfortunately the user doesn't realize what the problem is and then how to cure it.

In a two way proxy, where the proxy will handle both incoming and outgoing mail this problem tends to go away since the proxy itself usually has separate settings for both the Pop and SMTP servers. This also accomodates those systems that have different Pop and SMTP authentication.

Here is an article of a fix if you do in Endura.

http://www.eudora.com/techsupport/kb/2107hq.html

Basically the problem most likely will come into play if you have a provider that requires authentication for the SMTP session.

What occurs is that the mail client uses the Pop3 Modified name that a proxy such as Benign adds on for the authenticated SMTP login name.

In the case of Pop, B9 will strip the B9 off of the account and pass it through to login to the Pop Server, your password from your email client will follow on as well. This is possible because B9 added an entry in your host file that allowed your email client via its Pop account setup to find the B9 Pop proxy. Mail will flow from your ISP to B9 to your email client.

In the case of mail flow to the ISP SMTP server, the SMTP server will require an authentication name and password. Some mail clients without a separate SMTP configuration will just pass through the name provided in the Pop setup as well as the password. The password is not a problem for the most part since most ISP that require authentication will have the same password for both the Pop and SMTP servers. However the name can become a problem since it now has the extention added to it.

I don't believe B9 currently does anything on SMTP port #25

Well make up your mind Perry. First you refer to a problem when using the same address for the incoming and outgoing email, now it's if outgoing authentication is required. Confused

"such as ..." Yeah sure, in general, whatever. What about B9 specifically? In point of fact, B9 only parses incoming messages.

Right. That's now consistent with what I've been saying.

Sure but B9 has nothing to do with email in this direction. So the point is.... ? Confused

Once B9 changes the name of the login in clients that don't have separate SMTP entries, it certainly can affect mail in this direction.

Arrow Remember who stated it strips the B9 off for SMTP.

It strips it off for Pop only, which is what I stated. B9 adds .B9 to the address, the client does not.

Say again? The email client maintains the login name required by the server. Just how does B9 "change the name of the login in clients" ?

My apologies for playing fast and loose with the SNMP term. Yes SNMP is more properly limited to outgoing email traffic whereas POP deals with incoming traffic (to the client). B9 only deals with POP traffic, not SNMP traffic, granted. But....

I set up my client to find <popserver_address>.B9 ... which was assigned an IP address in the hosts file. That address reaches the B9 proxy. The proxy accepts the client's request for email at <popserver_address>.B9 and puts out a request for messages at <popserver_address>. So just how is B9 adding the .B9 extension? Question

But, if the address is changed for the Pop and SMTP uses the same address in the SMTP side of the tracks, then you can have a problem as B9 will not change it back for SMTP.

In a client that uses the same for both Pop and SMTP, the new B9 added to the Pop address will not be stripped for SMTP. This can be a problem.
