219 - Please try again later

[George Brackett]

I'm writing a school application that uses a mySQl database via the  
lib.Bmm.Database library, which has worked smoothly as a substack.  I  
just added as an additional substack the library libSmtp253 so I can  
email reports to students.  The new stack works just fine in the  
Revolution development environment, but any standalone I've built  
since I added the SMTP capability generates a dialog on entry that  
reports "219 Please try again later."  This dialog appears at the  
point of the first database access.

The message is coming from the engine, if my search is correct.  I've  
located some discussion of similar problems on the Use Revolution  
list in 2004, which mentioned a workaround for splash screen startup  
stacks (which I'm not using) and a possible engine problem with  
database access when there are more than two substacks.  (Heeding  
this, I eliminated a simple substack I was using in addition.)  I've  
tried various ways of creating the standalone by specifying  
inclusions or letting RunRev decide.  I removed and carefully re- 
installed the two libraries following instructions from Eric Chatonet  
in Scripter's Scrapbook.  All to no avail.

Has anyone else encountered a similar problem?  Am I doing something  
wrong, or is there some workaround I haven't found?  I would  
appreciate ANY advice, since my faculty needs this app and I'm stuck.

Thanks,
George
