Hi Noel, thanks for your reply. I know that unfortunately it's not a standard configuration of Postfix, but it's the only one that solve all my problem...

That's not really true. Or, at least, it is true if the only thing that matters about email is the content of each individual message, but it's a false dichotomy to call other functionality flashy GUI bullshit. The biggest weakness of Squirrelmail is that it doesn't support common desktop mail client functions such as drag-and-drop, threading, column sorting, indexed search, spam filtering and preview panes. That makes it considerably less user-friendly than a decent desktop client such as Thunderbird, particularly for high-volume mail users. As a lightweight webmail client, to be used as an infrequent alternative to a desktop client (eg, for collecting your mail when out and about with only web access), Squirrelmail is perfectly adequate for most users. But for day-to-day use as a long-term replacement for a desktop client, or for any user who gets a much larger than normal volume of mail, it's too lacking in functionality. That's what more full-featured webmail clients, such as Horde and Roundcube, are trying to address, albeit at the cost of additional complexity from a sysadmin perspective. As an administrator, therefore, you need to find out what your users actually need before deciding on what webmail client to provide them. And it isn't just about flashy GUI bullshit, it's about real features that make a practical difference for people with different requirements. Mark

My question is, who can I use as an smtp relayhost if the local host doesnt have one? If your ISP won't let you use their SMTP server, you'll need to configure your own or find someone who will let you use theirs. At this point your best bet is to find someone who will relay mail for you (generally this costs money), or switch to a hosting provider that has an SMTP server they will let you use. It's not difficult to setup postfix, however getting large ISPs to accept your mail can be a full-time job. If you're going to be sending out individual emails to people you know, it probably won't be a problem. If you're going to setup a mailing list or want to send bulk email, it's an entirely different story. For example, you can send a few emails to AOL and they'll go through. However if you send a bunch of mail to AOL or a few users click the SPAM button, suddenly you won't be able to send any mail to AOL, and getting this fixed takes work, which you may or may not want to do.

For this example, the domain used for $myorigin should be

localhost or localhost.example.com for this.
You decide where a domain should be listed based on the
domain's *primary* use, then use overrides, typically listed
in virtual_alias_maps, for addresses that are the exceptions.
Sounds as if you should list your domain in
virtual_mailbox_domains. Then $myorigin and $mydestination
would include localhost.example.com. Local users would be
listed in virtual_alias_maps like so:

Actually, this manpage says the result is: 200 SPACE text NEWLINE 400 SPACE text NEWLINE 500 SPACE text NEWLINE Where text is the result, or an error message in case of failure. Wietse

I've never run multiple postfix instances under Debian, but I'm guessing these postmulti errors have something (maybe everything) to do with the jail setup. -- Stan
Re: relayhost - what smtp server can I use?
Jeff Lacki put forth on 2/9/2010 10:53 AM: I have a situation with hosting.com, trying to setup a friends postfix config. Since I knew nothing about them I asked him to find out what their smtp server was. They said that we cannot use it and gave us a link to setup postfix, however they show no relayhost (smtp) server in the config! My question is, who can I use as an smtp relayhost if the local host doesnt have one? Typically in a hosting or colocation situation you send smtp directly to the recipient domains' MX'en. You don't typically use an smtp relay in this scenario. Unfortunately snowshoe spammers abuse both colos and hosting outfits, so the IP(s) you've been assigned my have a less than stellar mail reputation. This is the same reasons hosting companies don't want customers using their relays. They don't won't their relays ending up dnsbls. You didn't provide your IPs so I can't check them out. Run your IPs through this and see how many hits you get: http://www.mxtoolbox.com/blacklists.aspx If you only have a handful of hits, at places like the five-ten dnsbls, you should be fine sending direct smtp mail. If you find your IPs are listed in spamhaus, sorbs, or barracuda , you'll have a serious uphill battle getting your mail through. This is why people buying hosting or colo with the intention of sending mail need to do more than topical research into potential providers before handing them the plastic. For example, $4.95/month VPS service is probably not a good candidate for hosting a legit mail sending host because at that price spammers have probably already run the IP reputation of the provider into scorched earth territory. VPS in general, from a spam fighter perspective, is not a good place to host outbound mail. VPS services are nearly block-on-sight for many spam fighters. -- Stan

Please don't speculate - there is enough bad information on the Internet. Postfix's built-in chroot feature is not applicable for commands that are run from the root shell prompt. The real problem is that DEBIAN has not caught up on changes in Postfix file locations. When multi-instance support was introduced, it was necessary to move files such as postfix-script and postfix-files from (non-shared) /etc/postfix to (shared) /usr/libexec/postfix. Wietse

Also Debian expects some machine-wide Postfix configuration files to be in the Postfix configuration directory, but with multiple instances, there there is more than one such directory. The solution is that such files should be in just the default configuration directory, and Debian- specific Postfix features that rely on them should look for them there. -- Viktor. P.S.

address rewriting with regexp
hello, maybe someone here can help. I am trying to rewrite a certain set of To address with regex when they are sent outbound from my mail server. I am trying to do the following: Can you rewrite this to 123456789@ smscountry.net to 123456789.mydom...@smscountry.net 12145524065.prodea_u...@smscountry.net. The number string is very dynamic and will be many different combinations. is there a way to do this with regex. I have tried /@smscountry\.net/ . mydom...@smscountry.net but this drops the number sequence. Any help would be appreciated. Andy
