I say this because I dont' fully understand it, but it seems to lose track of the TLS setting. This could potentially be very bad. While it is actually to strong in my case, I wonder if in other cases it might be too weak. Here is how it is reproduced for me: Launch kmail and use it only with identities that use TLS (for SMTP, POP3). Then try to send an email from an identity that doesn't use TLS. In my case, this is because this server doesn't support TLS or SSL. However KMail insists on using TLS, even though the configuration for the identity does not have TLS checked. The result is a message box that says that TLS is not supported on the remote server. If I shut down KMail, restart, then try resending before doing anything that uses TLS, it sends without any problems. I have reproduced this problem several times now. However I haven't done it in such smooth fashion as I descibe above, simply because I haven't investigated so far yet. I just know that is what happened so far on several occasions. 102989 1 kloecker 2002-10-31 01:07:11 +0000 Subject: Re: New: KMail loses/confuses TLS settings As I already wrote in a reply to George's message to kde-core-devel and kmail I think the bug is in the SMTP kioslave and not in KMail. Regards, Ingo 122457 2 staikos 2003-03-10 06:03:01 +0000 Ok I have diagnosed this. Here's how it works: 1) Send an email with an SMTP account that has TLS enabled. 2) Send an email with an outbound account of smtp://host (note nothing else there), to a host that doesn't support TLS. It will fail saying that TLS is not supported. Here is what the second SMTP (non-TLS) server says: 220 tomts24.bellnexxia.net ESMTP server (InterMail vM.5.01.04.19 201-253-122-122-119-20020516) ready Mon, 10 Mar 2003 00:00:11 -0500 EHLO 0 250-tomts24-srv.bellnexxia.net 250-HELP 250-PIPELINING 250-DSN 250-8BITMIME 250 SIZE 10485760 EHLP 500 Command unknown: 'EHLP' HELP 214-This SMTP server is a part of the InterMail E-mail system.

Is it possible that there is a variable not getting reinitialised in kio_smtp? 122462 3 staikos 2003-03-10 07:16:44 +0000 Subject: kdepim/kmail CVS commit by staikos: So I fix my own bug reports I guess.
