Question:

SendEmail fails on longer text emails

Mar 26 '15 at 09:19

below is the last error dump, but basically if I send an email that is above 2000 bytes, I get a smtpcrlf error. If I take the exact email and chop out a few bytes in the middle to make it smaller, it sends with no issues. I know that there are no issues with the CRLFs in the body. These are automatically generated emails, and they only fail when they go above about 2000 bytes. Does sendEmail send it in chunks or something like that that would cause the server to complain? This is hitting a Netsol smtp server.

Thanks for any suggestions.

My bad. It was a CRLF issue, a system function was putting a CR on a string. The email server was just selective/random about complaining. Fixed now, disregard the question.

First thing I'd do is try with the latest version (9.5.0.48) just in case it's a bug that's been fixed.
