Cyber Net Email Issue

Post by x2oxen »

Cybernet email servers are not accepting email with attachment from several local isps. I have checked it on my isp (T&N Technologies), Blue Net and confirmed from Nexlinx and Comsats as well. Does anyone else suffering from the same issue?

I also having the same issue with tcm.com.pk and nexlinx.net.pk email servers while sendfing emails t cyber net. I can assure you cybernet guys are really pathetic they won't admit this problem and will surely say you the problem is at your site without putting one minute effort on it.

I had a technical issue with cybernet back in 2005 and had been consulting with mohsin alam (karachi office) he also deal me in same manner.

So dear X2oxen it is useless to consult with them just put a complaint on PTA' site................ :wink: they will start running :evil:

Few months back I had the similer issue with cybernet and some other ISPs and the problem was that a switch was installed at pie or flag (dont remember exactly) and its mta was set to below standard size and its droping the packets and every time connection was lost at data transfere stage but some times small messages with just subject or a single line body able to transmit succesfuly.

cybernet guys are real gays I always have problem with them. sometimes they block sql access, some time a hosted website, some time smtp server and so... and on other end they never admit a single problem.
