Question about usage and meaing of options with zmtlsctl

[concept]

zmtlsctl --help
ERROR: account.INVALID_ATTR_VALUE (zimbramailmode must be one of: http,https,both,mixed)

What exactly does zmtlsctl do and what do all the options do?

Thank you

zmtlsctl <mixed|http|https>

Sets the mode the web server runs in.

mixed = https login, redirect to original port (eg, if you hit http://, it redirects to https for login then returns to http for session. If you hit https:// originally, the login is in https, and the session is in https).
http|https = http/https for everything.

Stop/start tomcat after running.

Okay. Now I now this sounds weird, but it seems as though when I select "http" or "both" (and restart tomcat) that it breaks SMTP authentication. Does this command modify anything that could break SMTP authentication (me sending mail through my server from an email program that supplies my username and password for authentication purposes)?

Thank you.

yes, this can break smtp authentication. If you change the mode, due to a bug, you'll basically need to reset the smtp auth host to the same value it currently has. (I know, but it works)

zmprov gs <servername> | grep zimbraMtaAuthHost
zmprov ms <servername> zimbraMtaAuthHost <authHostName>
