I am using Outlook Express. I am facing problem in sending e-mails since yesterday. till yesterday i was able to send e-mail with my domain smtp address and port 26 but from yesterday i am unable to send e-mails. when i disable rich text (HTML) format and use plain text then i am able to send e-mails
when i connect to free link.net (WOLS)dialup connection then i am able to send e-mails even in both rich text (HTML) and plain text format very smoothly. so the problem is at the end of PTCL. is there anybody having/facing same problem.
here is the error.
