Default USE flags

Why is PostgreSQL recommended? In most mail I have seen there is no SQL involved whatsoever. —a3li 20:07, 23 November 2011 (UTC)

The useflag? Well in this basic postfix setup, you don't really need any database backend, this much is true. I actually wrote/relocated this page as a sub-page from Complete Virtual Mail Server (which will link to the postfix installation).
The reason for a database backend? Be it ldap, postgres, mysql etc? Easy, to have mailboxes independant of local 'passwd' users. I do think I stated that it was recommended, if wanting to do more with postfix then just a simple local only mailserver. The flag won't hurt btw, but yes, if only a local postfix install for a few users is required, on a single domain, then strip this flag.

USE flags and bits

Talk status
This discussion is done as of May 3, 2017.

Couple of points/questions:

  • hardened USE flag is not recommended. It is just a hack to get around a hardened-gcc-3.4.6 bug. You only need it if you are on hardened profile and using hardened-gcc-3.4.6. You should not need to turn it on manually.
  • vda USE flag is certainly not recommended. VDA patch does not play nicely at edge cases.
  • soft_bounce should only be turned on during testing. Perhaps a note to comment it out during production would be prudent.
  • -v verbose flag in master.cf should not be in general turned on. It does not provide any useful info -unless you are debugging postfix- and makes it rather slow.
  • address extensions is mainly used to deliver email to the correct folder (rather than all email to INBOX). Perhaps it should be more clear.
  • What does "When Postfix completes merging and the mailbox USE flag is set" mean? There is no mailbox USE flag.

OK to edit? Eras

Yes, if this still applies, make the changes. Thanks! --Maffblaster (talk) 00:08, 4 May 2017 (UTC)

Security issues

Talk status
This discussion is done as of May 3, 2017.

telnet from another box does not explicitly warn that telnet sends passwords in plain text, and is a BAD IDEA to preform these tests.

also a section should be added noting that http://toolbar.netcraft.com/site_report will tell you if your domain/ip has been blacklisted for spam, and if so contains links to un-blacklist. (i went through with these problems for centos sendmail, though they are applicable to gentoo postfix, and other mtas.) 666threesixes666 (talk) 04:35, 22 December 2013 (UTC)

Then add it. --Maffblaster (talk) 00:08, 4 May 2017 (UTC)

rc.config for postfix

Talk status
This discussion is still ongoing.

I can't find any instructions re rc.config.

As in "# rc-config add postfix boot"  ?

coz I found after a reboot, postfix wasn't working so I had to add it for it to be started automatically.

I think you mean rc-update. If you think it can enhance the article, go ahead and add it. --Grknight (talk) 14:09, 16 January 2020 (UTC)
