Tell me if there is something wrong with email routine

Please call Add methods in a loop, once for each address.
Please check sample projects.

The most important thing is to check what happens. And you can do this only with log files.

Same code works elsewhere… I’m betting your string literals are (invisibily) different.
I’ve seen some very odd situations with invisible garbage characters getting introduced by the IDE.
Required retyping the lines with literals to make work properly.

If you roll back to the old version before the “fix” does it go back to working?

@Christian Schmitz

Getting error 67, where can I find error codes?

https://curl.haxx.se/libcurl/c/libcurl-errors.html ?

CURLE_LOGIN_DENIED (67)

The remote server denied curl to login (Added in 7.13.1)

Thanks!

Be sure to check DebugData property for the log of the transfer.

OK Everyone Problem solved!

@Guy Kuo Came closest.

This app had the password in a constant, the other apps pull the PW from a database. The password was changed and didn’t remember that this one was still using the constant!

@Christian Schmitz I’m going to switch every email routine with your curlMBS. It seems so much more intuitive and I’m betting more solid.

Thanks!

Welcome & Thanks for the compliment.
