Strange fix? Can't send mail externally but can send locally using Outlook 2003
Folks, We have a user who can't send mail externally but can send mail locally (to people within our domain) when using Outlook 2003. But with Thunderbird the user can send & receive both externally & internally from the same machine. Naturally if they use any other machine they can send/receive externally using Outlook 2003. So it's just this one machine and it's Outlook 2003 that has the issue. I know it must be a configuration issue but all the settings are correct. I have tried reinstalling Outllook 2003 even cleaning up the registry before re-install. I am pretty confident I haven't missed anything to check but you never know. Has anyone else ever come across a similar issue? I realise this isn't a PostFix issue, or at least I suspect it isn't, but you folks must deal with client side e-mail issues as well as mail server issues so thought I'd poll the list to get some input. I doubt there is anything unique about our set-up. We have a barracuda spam filter in place and mail clients are set to use port 587 to send mail using our mail server. Linux mail.xx.com 2.6.27.25-78.2.56.fc9.i686 #1 SMP Thu Jun 18 12:47:50 EDT 2009 i686 i686 i386 GNU/Linux Postfix is mail_version = 2.5.1 Again if this isn't something I should ask the list please let me know and accept my apologies for the oversight on my part. Regards, William

Please don't post in HTML. And without logs, or at the very least an error message, anything would be at best a guess. May want to ask in an Exchange group as yes, this has nothing to do with postfix.

May want to ask in an Exchange group as yes, this has nothing to do with postfix. - Sorry about the HTML it won't happen again. The error message was: Relay Access Denied (smtp code 554) Or... mail just got stuck in the outbox and produced no error We don't use Exchange just PostFix. However, like a lot of Windows based companies we do use Outlook as our mail client. I have already asked the Outlook group about this without much success hence my shout out to this list and the use of Thunderbird. I should mention that I couldn't find anything in the logs to suggest the client even attempted to send external mail let alone was rejected by PostFix. But I don't know PostFix well enough to determine if I correctly checked all the relevant logs. Again any assistance would be greatly appreciated.

So > it's just this one machine and it's Outlook 2003 that has the issue. Right. It's not authenticating, as your logs show (you DID look in logs, did you not?) It sees no SASL mechanisms it understands, so rather than DTRT and fail with an error message, it attempts to continue without authenticating. > Has anyone else ever come across a similar issue? Dozens of times, if not hundreds, on this very list. Outlook is trash. Your search keywords are "postfix-users outlook auth mechanism". I believe I last answered this question in August (if it has come up since then, I might not have bothered to reply.) This is assuming, of course, that your user is trying to AUTH at a Postfix. If the Barracuda is the submission server, you should be asking Barracuda for support. Or better, as I suggested in August, refuse to support broken mail clients! -- Offlist mail to this address is discarded unless "/dev/rob0" or "not-spam" is in Subject: header

Thanks /dev/rob0 I am searching through the archives now. What is odd is that this is not reproducible nor is it affecting any other user with Outlook 2003. Any way for now Thunderbird will suffice for this user. Though I doubt I will be able to force a conversion away from Outlook if this issue gets worse. Most likely we would lose PostFix first, which I do not think would be in our best interests at all. Regards, William

If I remember correctly, in the config section of Outlook, when setting up an account, there is is test button. ; ; view or change existing e-mail accounts POP3 or IMAP depending on your system After insuring that the entries are correct, use the "Test Account Settings". What does the output show? Assuming that the mail is sent, the problem is probably not with MS Outlook. -- Jerry postfix.u...@yahoo.com TO REPORT A PROBLEM see http://www.postfix.org/DEBUG_README.html#mail TO (UN)SUBSCRIBE see http://www.postfix.org/lists.html Those who talk don't know.
