We are using a CDONTS object for automatically generating an
HTML file and send it as an attachment in the mail to our customers.
Server : WIN ADV Server, IIS 5.0

The HTML file atachment goes across properly when the size of the file is below 100KB. Whenever the file size is over 100KB we are getting error as below.

Error Type:
(0x80004005)
Unspecified error
/stat_ln_mail.asp, line 636

line 636 is mailobj.send

We have checked the CDONTS script by adding the same mailing script into a VB code and mailing the files. the file gets across without any problem on the same IIS/SMTP server.

Could someone please help in this..

change over to use CDOSYS instead. The size limit is then set by the mail server you are sending through.
