Re: copy to Sent items when sending from Pyhton

Mails sent via SMTP don't get saved in the Sent folder. You need to use IMAP or POP to save them. Or the SOAP API as already mentioned.
Some MTA's can be configured to save to IMAP the same time as they send the mail via SMTP.

Re: Incoming Mail DMARC check

It should be enabled by default in amavis (antivirus/antispam). SPF and DKIM are used when calculating the spam score. Example: amavis[21247]: (21247-02) spam-tag, <sender> -> <recipient>, No, score=-1.902 required=4 tests=[BAYES_00=-1.9, DKIM_SIGNED=0.1, DKIM_VALID=-0.1, HTML_MESSAGE=0.001, RCVD_IN...

Re: SpamAssassin Security Vulnerability

They seem to have updated just the "zimbra-mta-components zimbra-mta-patch zimbra-perl-mail-spamassassin zimbra-spamassassin-rules" packages (Ubuntu 16.04LTS) without releasing a new zimbra-patch. (zimbra-perl-mail-spamassassin is at 3.4.5-1zimbra8.8b3.16.04 now). I thought the practice wa...

A patch to allow Zimbra to work with rsyslog's precision timestamp format

I had an issue with some things not working after I changed rsyslog's timestamp format to precision. I commented out the line that sets traditional format in rsyslog.conf after installing fail2ban as it was having problems parsing the log timestamps. It showed as statistics and service status in the...

Re: 8.8.15 Patch 15 - How to enable TLS v 1.3 support?

I followed the only the last step in https://wiki.zimbra.com/wiki/Nginx_PackageUpgrade#How_to_configure_TLS_1.3 only partially: zmprov mcf zimbraReverseProxySSLProtocols 'TLSv1 TLSv1.1 TLSv1.2 TLSv1.3' This enabled TLSv1.3 on nginx (so any services you have going through it). I tested my installatio...

Re: Sending mails without username

If the client is in mynetworks it bypasses all the From address restrictions. Check what you have in zimbraMtaMyNetworks, you should only have your trusted networks there (e.g. private RFC1918 subnets). If it's not that, you possibly misconfigured something when you set the sender restrictions, or o...

Re: Sent emails missing in sent folder, zimbra client

That option controls only mails sent via the Zimbra web client. Mails sent via SMTP from mail clients (either authenticated from anywhere or unauthenticated in mynetworks) isn't saved in any folder. The responsibility to save a sent message is in the sending client itself, they have settings to cont...

Re: main.cf modification - zimbra way

In general you can find the mapping between Zimbra's keys (stored in ldap via zmprov or via zmlocalconfig) in /opt/zimbra/conf/zmconfigd.cf, where the POSTCONF lines represent postfix main.cf config lines, other config files are generated from their respective .in templates as set by the REWRITE lin...

Issues after enabling IPv6

I've had Zimbra 8.8.15 working fine for a long time in IPv4 mode. Since it seemed straightforward, I decided to enable IPv6. To prepare I added a public v6 IP and let it through the firewall, added the IPs to /etc/hosts, added v6 DNS and reverse DNS PTR at my ISP. Then I changed zimbraIPMode to both...

I tried to enable TLSv1.3 in 8.8.15p17, but nginx complained: [warn] 9488#0: invalid value "TLSv1.3" in /opt/zimbra/conf/nginx/includes/nginx.conf.web.https.default:41 Apparently TLSv1.3 is only available via a beta repository you need to manually add: https://wiki.zimbra.com/wiki/Nginx_Pa...
