Pegasus Mail & Mercury

Hi,

 

Since installing Service Packs 1 for Vista, I have a problem with sending email. Sometimes (but not always) the SMTP send fails with the following error:

 

Delivery has failed on the enclosed message for the following
reasons reported either by the mail delivery system on the mail
relay host or by the local TCP/IP transport module:

   *** TCP/IP error while processing job ***
   A network error has occurred while WinPMail attempted to send
   your message. This error could be caused by many conditions,
   including the following:
     * The remote host may have gone down.
     * Your network may have been broken or gone down.
     * You may have a configuration problem in your WINSOCK.DLL.
     * If running on a SLIP line, you may have experienced a
       timeout (increase the value in WinPMail's Network Config.
       Dialog), or the phone line may have gone down or suffered
       from excessive line noise.
   WinPMail will requeue your message and try again later.

 

Basically it seem to time-out? When this happens, the only way to get the message sent is to disconnect the ADSL connection, dial-up to the ISP on a modem, and re-send. This always works. But some outgoing messages (even fairly small ones) will simply not go through on ADSL, only on dial-up.

 

I have this problem on 3 Vista PCs recently upgraded to SP1, on three different locations and with three different ISPs... but the Vista PCs which have not been upgraded to SP1 are still working fine.

 

Any ideas....?

 

Thanks!

 

 

 

It would seem to have happened to the PC my wife works on as well. The university changed to Vista, and it worked till Monday, and the she started having the same problem. There is no common denomenator in the errors escept that it sometimes just doesn't want to send.

 Any Micro$oft gurus with an idea will be gladly listened to - I assume that the SP1 is the problem, as described in the subject.

 Thanks

 

I assume in both cases Vista is blocking WinPMail access to the internet.  Check the firewall settings, you might even want to turn it off for a bit to see if this helps.

Thanks for that.... but it does not seem to be the case here. Please see some more info below:

 

a. I disabled the Vista firewall but it did not help.

b. It does sometimes (though not always) send-out the 'stuck' message after several retries, I would expect the firewall to behave more consistently if it was to blame?

c. It does send-out fine with no problem at all when using dial-up and nor broadband.

d. It is more likely to happen with larger messages, the send process will go up to around 95% and then hang. But sometimes very small messages with no attachment will not go through either.

e. I tried changing various MTU settings in the Registry using programs such as DrTCP (after looking it up on the Internet and reading some discussions on similar issues), but again no luck.

f. As said above, it is not related to the ISP or SMTP server in use, I have this problem with three different providers.

g. I am using McAfee VirusScan Enterprise 8.5i Patch 5, it can not be disabled completely (other than by un-installing it) but it does log any blocked activities, and there is nothing in the McAfee log...

 

Thanks again.

Do you know what anti-virus software is she using - mine is McAfee (see post above), and it would be good if we could eliminate this from the list of suspects...

 

 

Well, if I am right and this is a Vista SP1 issue, then I guess more people will get this problem in the weeks and months to come.... I will monitor this space to see if a solution comes up.

I guess the Vista did not really take off then, seems like very few people are actually running Vista sp1...?

For what it's worth, I've got Vista + SP1 on my Vista Laptop (which doubles as my test system) and I can't get this error.

Can you capture the trace text in the dialog that WinPMail puts up when the error occurs? The trace text contains more information about the exact failure and may help work out what's going on. Alternatively, if you're using an older version of WinPMail that doesn't include the trace text, can you try turning on session logging and capturing a session log showing the error?

Cheers!

G'Day -

I use WinPMail on both a laptop with Vista (shows v. 6.6001 SP1) and a desktop with XP Pro (v. 5.1.2600 SP2).  As of Fri the 11th, both quit sending mail.  Can retrieve, but not send.  Trace shows this -- 15: Peer connect failure (the host has refused the connection). --

 

Have tried prior POP3 authenticate and login POP3 (which was used before) and no fix.

 

Help????

I suspect that the host is down.  What Host?  Can you telnet into port 25 of this host? Can you send via another SMTP host like GMail?

Sorry that I didn't include that info.  Host is up and running, I can send through mail2web.   How do I "telnet into port 25 of this host"?

> Sorry that I didn't include that info.  Host is up and running, I can send through mail2web.  

 Still did not provide the host name for testing from here.

> How do I "telnet into port 25 of this host"?

Try the following:

Start | Run telnet svl78zxa97.lmms.lmco.com 25

You will see something like the following.  The ones with the numbers are from the server, the others I typed in.

The host is www.tlcranch.com. 

I tried the telnet that you provided on my XP Pro machine and it ran something then did nothing.  On my Vista laptop, it said it did not recognize telnet.

Thanks for your help so far.

 

TJ.

 The host is www.tlcranch.com.

 I used tlcranch.com as the host since the www.tlcranch.com is a CNAME.  This looks like a good server response to me.  I entered the text in bold.

Start | Run telnet tlcranch.com 25

Since you cannot telnet into port 25 on this server it's quite possible your ISP is doing port 25 blocking.

I believe it depends on the type of Internet connection you have. As said, when using modem dial-up I have no problems at all, the intermittent fault only comes-up when using the ADSL connection (both at home and at work).

I may be down to some configuration parameters on the ADSL router, which may be a common setup for the UK but not elsewhere. Also, as far as I know in the US Cable connection is far more common than ADSL, while in the UK it is the other way around, so possibly US users will not experience this. Actual error message transcript to follow...
