Well i yet have not yet seen a single log that makes sense or
describes what you say.  The only full log i have seen was

 s-nail: >>> AUTH GSSAPI
 ...
 s-nail: >>> SERVER: 334
 ...
 s-nail: GSSAPI error: gss_init_sec_context / An invalid name was
 supplied
 s-nail: GSSAPI error: gss_init_sec_context / Success

That is what I get from the problem server with verbose=2 set. I have never seen a success from that server with verbose=2 set, so I can't show you a log of it succeeding. I do sometimes succeed _without_ verbose=2, but then there is no log. That was why I referred to the uncertainty principle - trying to observe the phenomenon appears to change it.

and that is a totally different error than what we now seem to
have to deal with, no?

No. You say that having two SERVER: 334 lines violates rfcs, but I only see them in cases where the message goes through. So even if they are a technical violation, they don't appear to be a problem for s-nail.

|Correct.  Alpine does not fail.  I have just tried it in debug mode with
|the 8.15.2 server and I see the same thing as with s-nail on the
|(successful) 8.14.7 server:
|
|IMAP DEBUG 19:31:15 8/17: 334 <lots of characters>
|IMAP DEBUG 19:31:15 8/17:
|IMAP DEBUG 19:31:15 8/17: 334 <some more characters>

Just like that

 s-nail: >>> SERVER: 334 <lots of characters>
 s-nail: >>>
 s-nail: >>> SERVER: 334 <some more characters>

Yes. the Alpine log for the problem server is the same as the s-nail log for the good server.

you have shown last, which is different to the initial thing.

Sorry, I don't know what you mean here.  Which initial thing?

You show the error in the first, but not in the
second, and the second is different to the first.  No???

Again, I am getting lost. I started this thread saying that I could sometimes, but not always, send through the problem server. You made the sensible request that I send you a log from a success and a log from a failure so that you could try to figure out what was going wrong. I tried to do that, but I couldn't, because there is never a success with that server when logging is turned on.

I did manage a success from a different server with logging turned on and showed you the log, but you don't like it because it has two 334 lines. Nevertheless, it is what got printed during a successful send from s-nail.

I can't think of anything else to say about the problem, so I suggest we drop it unless/until one of us has a new idea. I am sure other list subscribers will be glad.
