Hello, I think it is more of an SMTPAuth problem. Either SMTPAuth is not enabled or the authentication method is not set to PLAIN.
Check the option in advanced settings for: "Log onto incoming mail server before sending mail" (make sure it is checked) Best regards, Dirk blackpoint GmbH Friedberger Straße 106b 61118 Bad Vilbel -----Ursprüngliche Nachricht----- Von: Blueonyx <blueonyx-boun...@mail.blueonyx.it> Im Auftrag von Kasey Matejcek Gesendet: Montag, 25.

Anything older than 2010 is pretty much useless these days, and you really have to dumb down a server for 2011 (Mac) to work. >Subject: [BlueOnyx:23895] Mail sending Issue POP IMAP >I have 5209 server and in the last days client can't send mail outlook reports error Task 'x...@lkm.bz - Sending' reported error (0x800CCC80) : 'None of the authentication methods >supported by this client are supported by your server.' >on the server logs show >May 25 08:36:02 web sendmail[19036]: STARTTLS=server, relay=localhost.localdomain [127.0.0.1], version=TLSv1/SSLv3, verify=NO, cipher=ECDHE-RSA-AES256-GCM-SHA384, bits=256/256 >May 25 08:36:02 web sendmail[18885]: STARTTLS=client, relay=[127.0.0.1], version=TLSv1/SSLv3, verify=FAIL, cipher=ECDHE-RSA-AES256-GCM-SHA384, >bits=256/256 >and looking at updates the server did do update May 23 06:00:57 Updated: base-email-locale-en_US-1.6.0-0BX55.el7.noarch >witch is about the time the problem started >server is still receiving mail just can't send The Round cube client >can still send mail _______________________________________________ >Blueonyx mailing list >Blueonyx@mail.blueonyx.it >http://mail.blueonyx.it/mailman/listinfo/blueonyx _______________________________________________ Blueonyx mailing list Blueonyx@mail.blueonyx.it http://mail.blueonyx.it/mailman/listinfo/blueonyx _______________________________________________ Blueonyx mailing list Blueonyx@mail.blueonyx.it http://mail.blueonyx.it/mailman/listinfo/blueonyx
