Version: 1.9.9 (using KDE 3.5.9) OS: Linux Installed from: Ubuntu Packages Sending Email by some Email account does work with Thunderbird, but -not- so with Kmail, although of proper account configuration. (Some old Kmail under Mepis-5.0 works fine ...) The SMTP server is capable of PLAIN, at least with old Kmail this worked, but now, Kmail-1.9.9 complains that the server would not support PLAIN ... In follow, Kontact/Kmail responds with "5.7.0 Authentication rejected ...". Either this is a deep see/level (gcc?!) or whatsoever library(/malloc) bug, or, someone had changed something on Kmail's SMPT sending module, or ... Hopefully this will be fixed FAST. Or someone knows the particular special thing, what is going wrong with previously proper Email account setting (T-Online ...)!?! How fixing this fast on Ubuntu && Mepis where Kmail comes typ. in binary form? A long tail ...
Somebit heavy and strange: Old Kmails work, newer ones not on SMPT sending. Such thing should not occur (normally) ... Mepis-7.0 and Ubuntu-8.04 Kmails are not capable of to send Email.
Kmail works now ... The T-online provider does not want a full login-in, only the main registered symbolic one suffices. No forum or Kmail docu helped and detailed on this. The provider is also more than terse on such things. Anyway, Kmail and other KDE-PIM parts should be added a trace/debug mode for to find inner discrepancies. (Hopefully this info may help others!)
