Thread: unable to send mails in yahoo,outlook

not able to send mails with attachemnts in yahoo,outlook, also uploding files via wsftp to the server fails for files greathan size of 1 KB, even post in this forum also.
at first I am not able to browse all the sites also then I changed to opendns the problem solved. but this problem is still there.

I can't get you. can you please clear your question that what problems are you facing so that i can help you as much as i can.

my problem is simple and typical. I am not able to send mails with attachments and also mails without attachments if the message size is more than 1 KB in size (10 lines message) in yahoo. I got good connection for browsing, its really high speed but this the loophole while sending mails.

I am from guntur, andhra pradesh, when I get the dataone connection I am not able to access all the sites then I searched forums and change dns to Opendns and my problem solved. But my mail problem is still troubling me.

I am a web developer so I need to send files over ftp. downloading from ftp is o.k but uploading files to ftp fails if the file size is larger than 1 KB.

I am describing my problems in new threads because in this forum also I am not able to post my problem in detail (if the content is large then it is showing pagenotfound error).

But I am able to send mails in gmail only. Outlook and yahoo and wsftp are not full functioning.

please tell anybody the solution to my problem, I have been watching forum since 3 days.

Look as you have said that you are having problem with yahoo and other then i think if you are using their beta version then you should choose the classic as i also faced similar problem and i did the same thing and i was out from this problem. Let me know if it works.

I am already using yahoo classic, as you said I shifted to bet version and again to classic version. but its not working. not only this but I am unable to upload files to wsftp for the files, whose file size is greater than 1 KB.

I am not sure about wsftp issue that you are having, but with regards to not able to attach through yahoomail, I would suggest you to try to zip your files and then try to upload and send it. Not sure, it could work, just try as an alternative method and see if working or not.

I tried in those manners also, not only that even I am not able to send text mails also if the message length greater than 10 lines / 1 KB size. I am so bored/sad of this problem, nobody able to solve this problem, even bsnl customer care also not caring about this. I doubt the problem is in router settings (sending data packet size limit etc.) but I dont have clear knowledge about it.

Sankar singh,

This is because of a MTU issue in your PC. MTU is not but the Maximum Transmission Unit. If this is high or inappropriate, some attachements could not be opened or mails could not be sent. To get rid of this, you need to use, a tool Tcp Optimizer

helo ezhilaksh,
thank you very very much. I solved my problem due to your suggestion.
Its right that there is inappropriate MTU Settings found in LAN Settings. I corrected them after downloading TCP Optimiser Software as you mentioned.
I want to Share the steps I followed with others :
1. Open TCP Optimiser
2. I set my connection speed to 2,000 kbps as I got 2 Mbps
3. In General Settings : click on custom settings at bottom
3. Go To MTU and put 1500 there for first time.
4. and MTU Discovery : yes, Black Hole Detect : Yes, Selective ACKs: yes, Max Duplicate Acs: 3
5. Next I went to the tab "Largest MTU" and I started the test with speedguide.net, I got the maximum MTU response of "1453" for my connection, after that it was showing "Request Timedout" message.
6. Again I went to General Seetings : MTU : and overwrited 1500 to 1453
1453 is the appropriate MTU Setting.
Next I applied them restarted the p.c and it works all fine now. thanks once again.

I feel so happy abt the thing that my suggestion has sorted out ur issue

Still no luck for me........anything else to try????
