Description
This contrib will setup a new, independant qmail instance, running in a chroot. This instance can have its own configuration. It'll only be usefull in some rare condition, where:
- You send your email directly (not through a SMART host)
- You sometime send relativly big mailing (several 100 or 1000 at a time), so you do not want to reduce the global remote concurrency limit
- Some of the remote domains have a very low concurrency limit
I've build this contrib (with the precious help and advices from Charlie Brady) especially for this: domains @orange.fr and @wanadoo.fr (big french ISP) only accept 2 concurrent SMTP connections. So, when someone send, say 30 email to those domains:
- The first 2 mails are accepted, the 28 remaining get a deferral
- Next time, 2 mails are also accepted, still 26 to send
- etc...
The problem is that, time between retries is exponential, so, just for those 30 mails, it could take several hours, or even days for all of them to be sent.
With this new contrib, you can set a very low remonte concurrency limit, and only send mails to problematic domains through this instance (the main qmail instance will route mails to those domains with a smtproutes rule)
Requirements
- SME Server 8 (not yet working on SME9)
- You need to configure Fws repositorie
Installation
To install the contrib, simply run the following command:
yum --enablerepo=fws install smeserver-altqmail signal-event email-update sv u /service/altqmail sv u /service/altqmail-smtpd
Configuration
You can now choose the remote concurrency setting for this qmail instance, and the domains will be routed through it:
db configuration setprop altqmail ConcurrencyRemote 2 Domains orange.fr,wanadoo.fr signal-event email-update sv t /service/altqmail
Logs
You can see logs in /var/log/altqmail/current and /var/log/altqmail-smtpd/current

If you want to uninstall this contrib, just run:
yum remove smeserver-altqmail signal-event email-update
