twisted mail server - SMTP AUTH extension not supported
by cartermark46＠ukmail.com Dec. 30, 2003

Dec. 30, 2003

I'm trying to create a mail server in Twisted. I either get SMTPSenderRefused or SMTPException: SMTP AUTH extension not supported by server. What do I need to do to get it to work? --- Here is the server: from twisted.internet import reactor from twisted import mail import twisted.mail.mail import twisted.mail.maildir service = mail.mail.MailService('ExampleMail') smtp = service.getSMTPFactory() pop3 = service.getPOP3Factory() domain = mail.maildir.MaildirDirdbmDomain(service, '/temp') domain.addUser('salvador', 'gala') service.addDomain('dali', domain) reactor.listenTCP(25, smtp , interface='dali') reactor.listenTCP(110, pop3 , interface='dali') reactor.run() --- Here is the client that tries to send an email: import smtplib from email.MIMEText import MIMEText addr = 'salvador@dali' msg = MIMEText('Body of message') msg['From'] = addr msg['Subject'] = 'Note to myself' msg['To'] = addr server = smtplib.SMTP('dali') server.login('salvador', 'gala') # see note 1 server.sendmail(addr, addr ,msg.as_string()) server.quit() --- Notes: 1. If I keep in the line: server.login('salvador', 'gala') # see note 1 the client complains: server.login('salvador', 'gala') File "C:\Python23\lib\smtplib.py", line 546, in login raise SMTPException("SMTP AUTH extension not supported by server.") SMTPException: SMTP AUTH extension not supported by server. If I comment it out, the client complains: SMTPSenderRefused: (451, 'Requested action aborted: error in processing', 'salvador@dali') and the server prints the message: Failure: twisted.cred.error.UnhandledCredentials: No checker for twisted.cred.credentials.IAnonymous, twisted.cred.credentials.ICredentials ... smtp.py:553: DeprecationWarning: Returning None from validateFrom is deprecated. Raise smtp.SMTPBadSender instead "Raise smtp.SMTPBadSender instead", DeprecationWarning"

NEWBIE: ishexdigit revisited
by engsolnom＠ipns.com Dec. 30, 2003

Dec. 30, 2003

After looking at the suggestions for a ishexdigit method, (thanks again), I decided on the following, partly because I don't have to import string, and I believe it's pretty readable by Python newbies, which we (including myself) have at work: def ishexdigit(sx): ix = 0 for cx in sx: ix += 1 if not cx in '0123456789abcdefABCDEF': return 0 if ix % 2 == 0: return 1 else: return 'Extra nibble' # Try it out: sx = '0123abcDEF' # 5 bytes print ishexdigit(sx) if ishexdigit(sx): print 'All hex' else: print 'Not hex' sx = 'S123abcDEF' # The 'S' is not hex print ishexdigit(sx) if ishexdigit(sx): print 'All hex' else: print 'Not hex' sx = '123abcDEF' # 4 bytes plus a nibble print ishexdigit(sx) if ishexdigit(sx): print 'All hex' else: print 'Not hex' Results: 1 All hex 0 Not hex Extra nibble All hex Notice that the user is warned (if he/she cares to be), that the string isn't on byte boundries.

I would suggest a moratorium on new projects for a few months to research better names, improve doc strings and documentation, add examples & tests, rclick, provide better API compatibility with existing applications to ease relearn & reuse problems and add external scripting ability to existing applications. usability 101. better names would imply higher score in searches and could cut the number of duplicate started projects. not that all the duplication of effort is wasted. part of what makes python so much fun is that you can whip up a solution from nothing sometimes faster than researching what is available. probably only 10% of the one off scripts posted to c.l.py have the simplest docstring describing what it does and where to get an update if it becomes available. great that people make this available so is just an observation. > What would your favorite be? a timer capable of alarms or starting programs with various ways of specifying the event, weekly monthly don't start untill, stop after date, user defined, etc. b sorting out the os.py mess under "msys" the bash shell for mingw32. is it posix is it win32, are they forwardslash, backslashes or mixed, will python itself ever compile clean in mingw, will readline or any of the 10 variants available ever work without incompatible patching and knashing of teeth. the path to hell is paved with claims of backward compatibility. it is a wonder that as much works as does work so well. but as a dream funded project, this would get my vote. e please forward all spam to "me"<u%63e(a)f%74c.go%76> ________________________________________________________________ The best thing to hit the internet in years - Juno SpeedBand!

When to put my modules
by Bob van der Poel Dec. 30, 2003

Dec. 30, 2003

I'm working on a moderately sized application and I'm planning on having a fair number of modules. The only question in my mind is: where do I put the modules ... and how do I let python know about them? I could put them with the rest of the python lib, but I'm not really presumtious to do that. I can keep them all in the current directory, but that forces the user to chd to a certain location all the time. Best, I think, is to put them in a program specific location. My program needs some other data files, etc. so I'm thinking that I can just put the python stuff in /usr/local/lib/MYPROGRAM/modules. Okay, but what about when I'm just working on them? In this case I'd like them to be in my current working dir. Is there a magic line I need to add to the top of the main module to set the path up? Apologies if this is covered in a document...but I can't see to find anything. Maybe this is a faq? -- Bob van der Poel ** Wynndel, British Columbia, CANADA ** EMAIL: bvdpoel(a)kootenay.com WWW: http://www.kootenay.com/~bvdpoel

strftime - %a is always Monday ?
by richardshea＠fastmail.fm Dec. 30, 2003

Dec. 30, 2003

Hi - I'm trying to use strftime to output the day of the week but I find that I always get told it's Monday. I have tried day, month, year etc and all come out correctly but as soon as I use %a I get 'Mon'. I'm running Python 2.3.2 on a Windows 98 machine. Can anyone suggest what the problem might be please ? This is a segment of the code which is manfests the behaviour ... >>> from time import localtime,strftime,time >>> lst1 = ['2003','12','27'] >>> strftime("%A,%d (%w %y %m)",[int(lst1[0]),int(lst1[1]),int(lst1[2]),0,0,0,0,0,0]) 'Monday,27 (1 03 12)' >>> ... whereas the 27th was a Saturday ? thanks richard shea.

Problem with frozen app: compatibility between Unixware and SCO Unix
by mkent＠webmd.net Dec. 30, 2003

Dec. 30, 2003

I need to deploy a Python app on both SCO Unixware and old SCO Unix boxes. We freeze the app under Unixware, and set the compatibility flag ('elfmark -t udk') on the resulting executable. We successfully did this using Python 1.5.2. Recently, we decided to upgrade the app to use Python 2.3.2. Unfortunately, we've just discovered a nasty surprise. Under 2.3.2, os.path.isdir() returns True on Unixware for an existing directory (/tmp, for example), but returns False under SCO Unix. Ouch. Note that this has been verified using a test program that is frozen under Unixware, then run on Unixware and SCO Unix. We don't currently have a python interpreter on the SCO Unix box. Because of the way a frozen app is involved, I'm thinking that this is a binary compatibility problem, and will investigate further. We do the same 'compile under Unixware, deploy under SCO Unix' thing for many other apps that are written in C, without encountering this problem. Does anyone have any suggestions on how I can best proceed? Have you heard of this kind of problem before? What additional information would you like to read? Thanks
