verizon dsl outbound problem

« on: February 10, 2005, 08:25:40 PM »

I'm using my esmith server as a gateway, and I'm having issues with outbound email. I'm using verizon DSL, and I've configured my mail client (OE) to use their SMTP server (outgoing.verizon.net). People can receive this email at hotmail and yahoo, but not some other domains (gmail).

I tested this out be directly connecting my laptop to the dsl modem, and the email went through to domains that were previously unreachable.

Any ideas on what I should do to troubleshoot this?

Does esmith 'grab' the outgoing smtp streams (like it does with port 80/squid) and try to deliver directly? Under that assumption, I set up outbound.verizon.net as a smarthost, but this didn't seem to matter.

Yes.

Go to the mail log analysis panel and find out what outgoing messages have been delayed and why. Look in the qmail/current log file in the log viewer and you will see whether outbound.verizon.net accepted your mail messages. If they did, then you'll need to ask them what's the hold up. If they didn't, well the log messages will tell you why not.

Thanks ... this was very very helpful. I had tried the mail logs but I looked in the wrong ones. Your post allowed me very quickly to realize that Verizon now requires smtpauth. So if this page

http://no.longer.valid/phpwiki/index.php/OutboundSMTPAuth

were not blank, I would be in good shape.

From reading the forums, I suspect a good solution is out of reach until 6.5 reaches stable.

But, I'll ask anyway: Is there a quick way to tweak it (ipchains?) so that e-smith doesn't do anything for outbound smtp (port 25?)

My server is currently used as a web server, firewall, file server and backup IMAP server, but not for outbound email. Can smtp be shut down without impacting the other services?
