Hi

I am not sure whwther anyone else is having this problem but it is starting to get on my T...!
When I try and send mail using outlook I get the following error message:
A time-out occurred while communicating with the server. Subject 'Late', Account: 'Mail', Server: 'smtp.iburst.co.za', Protocol: SMTP, Port: 25, Secure(SSL): No, Error Number: 0x800CCC19

I recently upgraded my PC and since then I have been unable to send or recieve any mails, and as usual no repsonse from the iburps website ( I am going to call the today!)

Settings:
POP3.iburst.co.za
smtp.iburst.co.za

seems the smtp server is screwed or something??:confused:

Yes, Webmail is working. Not sure about the smtp, cos I'm not using it

Have you tried smtp.wbs.co.za ?
 
Try this....

Mail servers:
*********
mail-01.cpt.wbs.co.za = 196.46.70.2 - Cape Town
mail-02.jhb.wbs.co.za = 208.67.219.40 - San Francisco (OpenDNS)
smtp.iburst.co.za = 208.67.219.40 - San Francisco (OpenDNS)
smtp.wbs.co.za = 208.67.219.40 - San Francisco (OpenDNS)
mail.iburst.co.za = 196.30.31.207 - Joburg
smtp.uunet.co.za = 196.7.142.136 - Joburg

DNS servers:
*********
IBurst:
196.46.70.1 - Cape Town
196.30.31.193 - Joburg

Verison:
196.7.0.138 - Cape Town
196.7.142.132 - Joburg

Open DNS:
208.67.220.220 - San Francisco
208.67.222.222 - San Francisco

Can't send mail through our office authenticated SMTP... = Send an email to the helpdesk to unblock your SMTP address, include IP address - If you are still having issues after they have unblocked your SMTP server, change the outgoing SMTP port number to 587 and enable encryption (SSL), this might not work in all cases but was my only alternative.

As per iBurst site:
Remember: if you're on a network only 4 mails can be sent out concurrently.
Server should be in “host forwarding mode” (NOT “DNS delivery mode”).
Server response setting set to 180 seconds.
Maximum mail size must be less than 10 MB.
Maximum number of recipients per message = 30

Settings have changed - see this post http://mybroadband.co.za/vb/showthread.php?p=803855

Hi Gents

Thanks for the Advice, I phone the iburst helpline last night and spoke with a very helpful gent by the Name oj Johnson Ramoshaba who was able to help me getting my mail partially working!:D
I can now receive mails but can't send any Now the error received is 0x800CCC0f which it seems is an error generated by the virus scanner on the smtp server, thus it appears that I am unwittingly and unknowingly trying to propgate some or other "nasty"!:sick:



Johnson has however said that he will log a call with his supervisor to further investigate and let me know what the problem ( and hopefully resolution will be to my problem!)



Then again maybe I need to resize my mtu to 1352, it is currently set at 1492!!!
the roported error can apparently be caused by an incorrect MESSAGE TRANSMIT UNIT (mtu) size!
Aslo turning off my Zonelabs firewall - (although Outlook express has external access for mail sends)

Information regarding this error can be found here:

Just an interesting question - why do we need to change the MTU size? What is iBurst's reasoning for using a different non-standard MTU setting?

Why can't they stay with the default setting of 1492 as used by almost all OS'es?
 
Default MTU for Ethernet is in fact 1500 - the MTU of 1492 is the default MTU of PPPoE connections. A PPPoE connection (in very simple terms) is one type of connection packaged inside another - a very basic type of VPN if you will. Now some of the 1500 bytes of the Ethernet packet is consumed for PPPoE overheads. PPPoE is used for ADSL as well - but most of the MTU issues are handled internally by the modern router-modem combos.

Reason for using PPPoE and not straight Ethernet (particularly in ZA) is that the ISPs want a connection inside a controlled pipe so that they can watch you with their big "i'm gonna cap you" camera :p

iBurst obviously also uses PPPoE for their connections - difference being their physical transmission layer being air. Now experience has shown that sending a full 1492 packet + PPPoE overheads has produced a large number of packets that have 1 or 2 erroneous bits if data and are thus dumped. This dumping results in the considerable speed degredation. The MTU that is suggested by iBurst is the best compromise between error prevention and transport efficiency.

As far as i know... :D
 
Hey ALL,

I've had this problem on my laptop with suddenly not being able to send and receive my email from my ISP (not iBurst), as well as accessing secure banking sites etc.

This started happening more than a month ago. I contacted the Iburst Help(less) desk, and got nothing out of them. Then two weeks later I contacted them again, gave them the whole story AGAIN - and still NO resolution.

I eventually re-installed my OS and Office (ALL from scratch, reformat, reload...). Once done, the first thing I tested was sending and receiving email, as well as trying to access a banking site - NOTHING, NADDA, F*kk*L change.

Went through this forum - changed my MTU, and WHALLA!!! she's ALIVE!!!

Thanks to this forum. Now maybe the iBurst Help(less) desk can learn something from this. They did NOT even think to mention the MTU issue.

Cheers :-)
