Re: Problem: mail_fetchtext() incomplete result

Thanks Mark.

I wasn't aware of the single buffer for all mail_fetch***() functions,
but I'm converting the results to std::strings directly afterwards so
it doesn't affect the app.

Turning on debugging telemetry showed that the message is transmitted
truncated by the server. This is the Gmail IMAP server. I guess I'll
have to download the messages in parts and then glue them back
together again.

Thanks for your help!
