KMail 1,000,000,000th Second Bug Looms

If you did not heed our warning from six months ago and are still using KMail < (from KDE 1.x), you are advised to please upgrade to KDE 2.2 (or KDE 2.1.x) immediately. In about a week the bizarre KMail 1,000,000,000th second bug will strike, which can cause corruption of your mail folders. Details about the bug are available here.

The KMail developers recommend that users update to KDE 2.2, which includes a newer KMail with many other bugs fixed and many new features. According to KMail developer Daniel Naber,

The new version of KMail will use old mail files without problems.
However, once the new version is installed one should not switch back to
the old version because of changes in the index files and configuration
file. Just to be sure, we recommend that users make a backup of their mail
folder (~/Mail) and compress all folders before switching to the new

icannot send emails. comes up as an error.

By carol e smith at Thu, 2007/07/12 - 5:00am

I am having the same problem. What did you do?

i had a hard time receiving email too, by following their instructions.
But it turns out that told us to check required SSL in the advanced tab for port 995 to receive, 465 to send.

all have to be done is use their outgoing mail server: correspond to your account with them. and use port 465 without the check for outgoing port. and it works fine for me.

I have the current version of Eudora Pro, have been unable to restore my paid mode status (once advised that Eudora no longer provides TS nor accepts paid users), have Windows XPSP2, have used Eudora Pro for 12 years and will fight before I use crap webmail or crap Outlook, and I have AT&T-Yahoo DSL service with webhosting and forwarding by Yahoo (probably with premium service). I recently encountered increasingly more frequent but intermittant error messages with outgoing E-mails that inevitably require 2-4 tries to successfully leave my computer; your error messages give no reason. I have received differing advice from AT&T TS staff who have had me change my incoming and outgoing server info in Eudora from SBCGlobal to ATT but otherwise have made no substantial change. I've been advised that there are new servers and changes but that "AT&T does not support Eudora" as if Eudora were the problem. My suspicion is that AT&T unlawfully obstructs my Eudora E-mailing and if the problem isn't somehow fixed I want to confront AT&T in Court and/or before the PUC.

I have been working for two weeks trying to get my E-Mail to work, I have changed the numbers that you sent me, I can receive but it will not send I get a 500 error I am useing Incredemail can you help me I really need it. Thanks

By Hubert Young at Sun, 2008/09/28 - 5:00am

I need help sending out my e-mail.

By james bilderback at Mon, 2008/10/13 - 5:00am

I had this problem after updating for SSL security with AT&T Yahoo. After a lot of poking around, I finally figured out that the "automatic" updater from AT&T had created a new account which contained all the new information - the info. The old account, which had the information still remained. For some reason, all the outgoing mail was being sent under this account. Finally, I tried deleting the old account and now I can send email again.

What I did was go into TOOLS from the Outlook Express menu. Go down to ACCOUNTS. It is there that I saw "Fiona" (the new account AT&T setup using their automatic Outlook updater) and one that said This second one is what I deleted. (I figured this out by watching VERY closely the messges that flashed by after I hit the "send/receive" button)

As soon as I did this, I was able to send messages again. I hope this works for you.

By Fiona at Sat, 2009/01/03 - 6:00am

How do I remedy this problem? I can't send out email from Outlook Express since I changed over to sbc hookup. The Outlook is incredibly faster than the sbc yahoo mail. I have dial up.

By Sue at Wed, 2005/08/17 - 5:00am

Toggle the "My server requires authentification" when setting up your account (in the server tab). The same happened to me following installation of PALM OS, do not ask me why...

By jc at Wed, 2005/10/19 - 5:00am

Thanks for your advice. I have spent hours trying to figure this out and your simple solution worked!

By Ed Hanson at Mon, 2006/02/27 - 6:00am

I am using Olypia Comedia Master program and although I have signed up to process e-mail, all I get is the message that indicates that pop 530authentication is required. What is this and how do I get past this halting problem. I need to send out pictures and are unable to get past this.
Help please.

By James H. McLaughlin at Fri, 2006/06/30 - 5:00am

Yep - that was the right answer for me too. Thanks a bunch - simple.

By ak at Wed, 2006/08/02 - 5:00am

i am trying to get incredimail and they say go to this site help

By Kathi Bevan at Sat, 2006/07/15 - 5:00am

You need to make sure it sends with secure authentication in outlook or outlook express. Don't log in with secure authentication but send. It does work give it a try.

By Andrew Kopp at Wed, 2006/08/02 - 5:00am

Sorry, i was looking for how to fix the problem, figured it out myself. I dont know if somebody already answered the question lol skipped to the bottom, but anyways, on outlook express, go to tools > accounts > properties of the yahoo account needing fixing > servers tab > and all you have to do is check the box that says "my server requires authentication". Then just send all messages normally, all works. =D nice to help for once lmfao

Could you explain to me what to do for the 530 authentication to be able to send out e-mail

By Beth Snyder at Wed, 2005/08/24 - 5:00am

Go into incrediMail and under tools go to accounts. Highlight your connection and go to properties, Then go to Servers and under that put a check in my server requires authentication this wil clear up the 530 authentication error message. ken
