Got it, it was the spam checking I had in the smtp run script: rblsmtpd -r relays.osirusoft.com \ For some reason, I'm having a hard time connecting to that server sometimes. I'm hoping that was it. When I send emails from different places, it now comes through right away. Also, the smtp.monitor script works now. Thanks for the advise all.

It's probably a reverse DNS issue, I have that problem even with everything disabled: exec softlimit -m 2300 tcpserver -t3 -S -H -R It's just that the reverse DNS server is down when you're getting the 'wait'.

RE: [vchkpw] qmail smtp problem
But I don't understand how it can be a dns issue when I can connect to the port with no problem. It's just not giving me back the correct smtp response. After I posted the last message, it's now giving me the [220 ESMTP] line when I telnet to port 25.

RE: [vchkpw] qmail smtp problem
That sounds like you have a dns issue. Make sure the server is able to resolve properly and to test if you have a problem with the mtu set the interface to a lower value. The lowest being 576 with something like ifconfig eth0 mtu 576. But from what you just said, I would probably be looking at dns as well.

RE: [vchkpw] qmail smtp problem
Well, now I have to figure out what a DF bit is... I use a linksys wirless router for my router. How would I remove the DF bit on my router? I see the request coming into the qmail-smtp/current file. What I do notice when I do a tail on the smtp file is when an email first comes in, I see the: tcpserver: ok but for some reason, it takes a long time to deliver that test email. 3-5 minutes... to show up in my inbox.. Also, I just tried to telnet to port 25 and do the smtp commands and it was just hanging: telnet my-server 25 Trying ... Connected to . Escape character is '^]'.

RE: [vchkpw] qmail smtp problem
The last time I had this same error it turned out that it was broken routers/hosts upstream from me that was setting the DF bit. I just dropped the MTU on the qmail box and all was sweet again. Since then I have put in a new IOS on the cisco router and I now remove the DF bit at the border. May not be your problem but would still be worth checking.
