I just changed the SMTP server I've been using from the one provided with my Windows 2003 Server machine to the one at my ISP (Covad). Since I've been using my ISP's server, I notice that emails sometimes don't go through and get an error when SMTP.Send is called that says "Unterminated line sent by server." Does anyone know what may be causing this?

Hello Phil,

The problem you describe would occur if the server responded to a command without adding a crlf to the end of the response. It seems to be specific to the server you are connecting to. Therefore I would request you to please create a Trace log of the communication, and then post the last few lines of the log (just before the error occurs).
You may use the Trace event to create a Trace log. For more details, please refer the help file.

A similar issue was discussed here; make sure it's not the same at your end.

This seems to be a random error. Would it be possible to have the SMTP control automatically retry a certain number of times to send the email without returning an error after only one try?

Hello Phil,

Unfortunately there is no direct property in the SMTP component using which we can try resending the mail to a certain number of times.
However by handling it at the layer level by writing some custom code, we can achieve the desired.

Have a great day.

Arjun
