Re: Anyone else getting a lot of "502 Bad Gateway" errors accessing the forums?

Interestingly, right now with Safari on MacOS Sonoma I get continuois 502 Bad Gateway errors, but if I open the forums in Firefox I can log in and send this reply no problem.

Re: Zimbra demo license request

You can get a Trial License from this page:

https://www.zimbra.com/product/download/

at this link specifically: https://www.zimbra.com/connect/forms/?f ... al-license

The issuance is automated; typically you'll receive the trial license in just a few minutes.

Hope that helps,
Mark

I also opened a Support Case last week. Support confirmed the behavior and assigned the ticket with a high priority.

[SOLVED] Zimbra 10 - Can't Upload Microsoft Office Documents

Zimbra has always been able to block files with certain extensions, like *.scr, *.ocx etc. but now the new attribute 'zimbraFileUploadBlockedFileTypes' can also be used to block by File Type -- regardless of the extension. This is a good thing, but I don't seem to be able to find any documentation a...

ghen,

Thanks for the heads up, looks like the option is silent-discard not silent_discard.

Re: SMTP Smuggling - Spoofing E-Mails Worldwide

I'm not sure that's correct. Weitse's most recent document says that that attribute is supported in all versions of Postfix. I meant to say: which Zimbra's default config doesn't have enabled (unlike "smtpd_data_restrictions = reject_unauth_pipelining"). Aaahh! Ok then! Hopefully we'll ge...

Re: Test Sender_PCRE

That format looks correct.

You may also want to add at the top of that file:

Code: Select all

/@.*@/       reject
To prevent nested spoofed From emails.
