Outlook SSL and Authentication issue

[bhwong]

Hi,

I have no problem with using Outlook Express "Use same settings as my incoming mail server" to send email. But on Outlook, the only way to send email successfully is to use "Log on using...(enter user name and password)" Why is this so? Is this Outlook or Zimbra problem?

Also, I have type this command to allow both http and https web access: zmtlsctl both.

Does this affect whether POP has to use SSL too? Cause I notice that in the network edition, I have to use SSL to check email and it is very slow. How do I disable SSL at Zimbra Admin?

Thanks,
Boon Hong.

For POP/IMAP TLS is managed by zimbraPop3SSLServerEnabled and zimbraImapSSLServerEnabled.

You mean running command line: zmprov -l modifyServer SERVER zimbraPop3SSLServerEnabled FALSE?

So Admin page can't do this? I don't really want to disabled SSL, but give user the option whether they want SSL or not. Currently, users are forced to use SSL just to be able to download email, yet don't need and cannot use authentication to send email in Outlook.

Ideally, I want to let users to download email using SSL merely as an option, but want to enforce authentication so that other outside domain users cannot abuse our email system to blast junk.

Please advise.

Zimbra talks on non-secure as well till you have below 2 config variables configured to TRUE.

zimbraImapCleartextLoginEnabled: TRUE
zimbraPop3CleartextLoginEnabled: TRUE

So to talk both you need to set these as well as SSL ones to true.

possible outlook corrupt?
I had same problem with unknown problem, and now I'm using thunderbird for all computers in my office..

Outlook* > /dev/null

Can't be outlook corruption cause not a single copy of outlook in my office of over 50 PCs can send email without using "login on using" option.

btw, I realize that to enable non-SSL download of email, simply check "Enable clear text login" at the POP Tab in the Admin GUI. haha... never expect this to associated with SSL. Very misleading.

In my case, I've outlook express problem, in other sites [branch] outlook work great, so I just replaced outlook [problem] with other mail clients [thunderbird].
