SMTP: Socket error 10051
We currently provide a POP3 service for a client using IMail v 6.0.02.362 running on IIS4. We now also wish him to be able to use SMTP.
However, when our client tries to send mail via the SMTP address we have provided, he gets socket error 10051. We are not blocking access to port 25, which I believe is a common cause for this problem.
Does anyone know how we can get our client to use our SMTP server?
(Please let me know if there is any other information needed to help with a diagnosis!)
