Do I need squirrelmail for Outlook to work?

[IrishDoc]

I had to disable squirrelmail in-order to get access to isp3 in browser. Do I need it to be enabled for Outlook to work? If so can you give me some ideas where to look for the problem? If not, then I am having another issue as Outlook will not setup to receive or send emails.

This is what I have without running squirrelmail

[till]

squirrelmail is not required to use email accounts with external mail clients like outlook or thudnerbird.

Btw, you dont have to disable squirrelmail to use ispconfig mail. I guess you just used a wrong alias for squirrelmail, the correct alias is /webmail while the wriong alias would be /mail. Edit the squirremail configuration file and set the alis to /webmail as described in the perfect setup guides.

This is what I had setup before and I have now reinstated squirrelmail and it is working without problems with isp3. But I am still unable to ping smtp.kustomhosting.net, I am not sure what is wrong and I am also unable to access webmail.kustomhosting.net And now my domains are going directly back to squirrelmail again, I disabled it again.

This is most likely adns problem and not related to email at all. Have you created dns A-Records for smtp.kustomhosting.net and webmail.kustomhosting.net that point to the IP address of your web server in the dns server that is authoritive for the zone kustomhosting.net

And now my domains are going directly back to squirrelmail again, I disabled it again.

The reason for that is that you mixed IP address based vhosts with wildcard vhosts in apache. If you create a IP based vhostlke the one that you created in the squirrelmail configuration file, then all other vhsost on your server have to be ip based to. So you have to select the IP address and not * in all sites that you create in ispconfig.

Is this correct

[till]

This is correct for the smtp subdomain, but you dont have a webmail subdomain.

[IrishDoc]

I am able to ping both the webmail and smtp addresses but cannot seem to get outlook send the test email. It is not able to login to the smtp outgoing mail server. Any ideas.

[till]

Did you enable smtp-auth in outlook and do you use the smae username and password then for imap?

Post the errors that you get in the mail.log.

[IrishDoc]

This is the error and the setup

Send test e-mail message: Outlook cannot connect to your outgoing (SMTP) e-mail server. If you continue to receive this message, contact your server administrator or Internet service provider (ISP).

Make sure that Postfix is running and that no firewall is blocking port 25.
