I get:
socketlib.eu:120 in function SockRead()
A machine-level exception occurred during execution of this statement
... called from smtp-lib.e:18 in function smtpRead()
... called from smtp-lib.e:34 in function smtpReadCode()
... called from smtp-lib.e:94 in function PostMail()
... called from smtp-lib.exu:14
--> see ex.err

Irv,
Thanks for being willing to test this out! You're getting the exact
same error I was. Peter thought it might be something in socketlib.eu
or his misunderstanding of how the library works.
At a glance, would you know why this error is happening? I traced it
down to a routine where single characters were being read from a socket
(don't have the source with me right now).

3. RE: J. Brown, Pete Eberlein or Irv Mullins - socketlib.eu
This looks like common problem that some programs have linking to the
errno variable on RedHat 9. The problem is that reading errno as
variable is unsafe in threaded programs, so they took it out altogether,
and have a function to read errno instead. It is interesting that the
comments indicate that the author was aware (poke, poke... jbrown? 
of this and coded the errno interface to the function incorrectly. To
fix it, comment out line 71, and add these lines immediately after it.
errno_var = define_c_var(lib,"errno"),
errno_location = define_c_func(lib,"__errno_location",{},C_INT)
function errno ()
if errno_var != -1 then
return peek4s(errno_var)
else
return c_func(errno_location, {})
end if
end function
And then at what used to be line 120
if peek4s(errno) != EAGAIN then
change the whole if statement to:
if errno() != EAGAIN then
if DEBUG then
puts(DEBUG,"READ: errno is "&sprint(errno())&'\n')
end if
end if
I haven't really tested this though. If it doesn't work, let me know.

Thanks, your fix works fine.
