Not your usual project but here goes.
I use a laptop for one of my businesses. I am unable to send emails from the laptop. There is no problem with hosting, ip or my server. The issue is with the laptop and port 25 i believe.
I know this is not your standard project but if anyone is able to offer assistance it should be a quick fix.
I am available on msn messenger and will leave gaf feedback as soon as it is completed.
I can work with you for an hour to troubleshoot the problem. I am based in the USA, have over 15 years experience and can help via IM, Live Chat and/or Telephone.
