View 2 Replies View RelatedGeneral :: Configure Kmail To Use Different Smtp Servers For Different Identities
Feb 8, 2010I have username1@domain.com and [URL] I want to send emails to two different groups of people and use a separate smtp server for each account so people that receive emails from username2 don't know about username1 account. At the moment I have to manually go into settings and change the default smtp server before I send the message. So I basically want to associate an smtp server with an identity. It doesn't seem that this is possible to do. I do know about the "Reply to Address" option but this is not what I want. For starters my smtp server won't allow this operation to take place.

General :: What Is Easiest Smtp Server To Setup And Configure?
Feb 25, 2010I need to setup a mail server, purely for relaying mail to a MS exchange server. A previous employee used Postfix on CentOS. I have limited Linux knowledge and no experience with any mail server software other than MS Exchange, so we cannot continue with this solution (unless I can find a way of managing it all from a gui). Does anyone know of an MTA that can be configured completely by GUI? Everyone says sendmail has millions of features and loads of documentation, but I simply do not have the time to learn it. I need something that can be configured with minimal knowledge and via GUI, not command line. The only reason I'm not using Exchange is to try to save money, and hopefully it will be more secure.

View 2 Replies View RelatedGeneral :: Transparent Squid - Iptables Syntax And Unable To Use Outlook To Access SMTP And POP3
Feb 10, 2011I've set up Ubuntu 9.04 (desktop) at home in a lab environment (workgroup rather than domain) and have configured Squid. Everything works fine but, when I took it to the next level and made the proxy transparent, my problems began. I can still access sites (having pointed the XP Pro client to the squid box as the DG) and the sites are logged in /var/log/squid/access.log but I am unable to use Outlook to access my SMTP and POP3. I guess that the setup is blocking ports 25 and 110 and I'll need to configure iptables to forward packets destined for these ports directly to the "real" DG, rather than the Squid box. Here's the set up:
A single NIC (eth0) on 172.19.0.250 / 16 (static) ADSL router ("real" DG) on 172.19.0.1 I executed iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 80 -j REDIRECT --to-port 3128 My squid.conf:
