V2012 Error in Cognos when mailing reports
SYMPTOMS
Some scheduled reports fail to send, the schedule log shows an error message.
ERROR
CNC-SDS-0335 Error returned from SMTP Server. The error message was: [552 5.3.4 Message size exceeds fixed maximum message size ]. The message could not be sent.
ANSWER
This means that the report to be mailed is too large. If the mail contains multiple formats (HTML, XLS, PDF), try to send these seperately to see which one fails. Sometime HTML reports can get very large when containing a lot of formatting. In that case it might be better to mail the report in Excel format, or try to simplify the layout and formatting of the report.
