Version: 1.11.2 (using 4.2.2 (KDE 4.2.2) "release 110", KDE:KDE4:Factory:Desktop / openSUSE_11.1) Compiler: gcc OS: Linux (i686) release 2.6.27.23-0.1-default When a message is replied to,I get stuck with the error message which is fully described in the attached screenshot. The message purported to be from server is misleading,because this message was sent from 'outlook' and I added no address.I just 'Reply to all'.My colleagues using 'outlook' face no such problem.They obviously share the SMTP server with me. I moved to kmail because I suffered this constant problem with Evolution and Thunderbird.But,kmail is not free from this bug either.
Created attachment 34706 [details] Kmail-'Too many Recipients' error mesage I always face this bug whenever I 'reply to all' with lot of addresses in the CC list of incoming message.
The message you are seeing is an error message from the SMTP server, it doesn't accept that many recipients. Nothing KMail can do about this.
Consider this,I work in an Office where I am the only one to use Linux/KDE.My Colleagues and me all receive a message.My colleagues 'reply to all' from their outlook,they do not get this error.I 'reply to all' from Kmail,I receive this problem.This could be a server problem,but if 'outlook' can negotiate it without any error,why kmail cannot do that? This is the one most annoying problem using kmail.I urge you look into this behaviour,as you are in a position to understand this,being developer.This problem is faced by only opensource users (of kmail,evolution,thunderbird).
There are, at least, two ways of send a "reply to all" to an SMTP server: * Send SMTP cc: comands (opensource mail programs way) (less work for the SMTP server) * Put mime cc: headers (privative mail programs way) (more work for the SMTP server) I guess your SMTP server is also privative and it is not able to handle the standard in its full extension.
