Relay on RHEL ES 3 with Sendmail 8.12.11

Hey Gang,

I've posted here before with a similar question but I was unable to resolve my issue despite some great help. I hope I'm successful this time.

Our Tech Admin left a year ago for another job so all tech duties have been dropped in my lap, to go along with my already overflowing plate of duties.
It's been a year but because of my other duties, I've really only had about 3 weeks experience using Redhat so please be patient and I'll try my best to follow and give all the info you need to help me.

We're running RHEL3 with Sendmail 8.12.11. Due to an intrusion 2 years ago, our box was totally closed off in terms of relaying but now my boss wants to be able to check his email on the road using his laptop which means a dynamic IP.

I've researched Poprelayd but had no luck getting it going, I'm not looking over SMPT-AUTH to death but because of a lack of experience I'm quite nervous to create problems I can't easily recover from. I'll include some more info in hopes that somebody can make some suggestions or perhaps help guide me through this?

RHEL3 with Sendmail 8.12.11
All updates have been installed including PHP and MYSQL but I have no idea if, in fact they're working. (I know, total newbie)
Boss wants to use his Entourage software to keep checking his email.

If you need any further info, please feel free to ask.

Also, if anybody knows of a great resource to help me get started in learning what I need to know as an administrator, it would be greatly appreciated.

Kind Regards

I meant to add that I've seen things like Open WebMail, SquirrelMail, and RoundCube. Would you recommend either of these?

One thing we absolutely need is access to something that will allow attachments.

Okay, I think I've got everything up and running for SMPT AUTH. I've tested this from outside the network and it seems to authorize me and then it immediately kicks me back off again. When I checked the maillog I see this line for every time I attempted to connect:

"did not issue MAIL/EXPN/VRFY/ETRN during connection to MTA"

There's obviously something I've missed or forgot to do. Any leads on where I should look?

I have searched around for answers, I honestly have, but the things I'm told to check, seem to be okay so there's got to be somebody out there that can help with this.

I did find this but is it a safe option?

Hi All,

Regarding "did not issue MAIL/EXPN/VRFY/ETRN during connection to MTA, Please check on your is there FEATURE(`dnsbl', `', `Rejected - see')dnl line. If it so please make it dnl for the same that means comment it. Then recompile your and then restart your sendmail. You will not have this problem and also you will get all mails which was not able to receive earlier.

This is due to closed the services of ( from 31st Dec 2006 onwards.

Pardon the *bump* but I really need to get this resolved. Any and all help is greatly appreciated.

I've looked through the LQ Tutorial on SMTP AUTH and I did find one thing I was missing but it's still not working.

I hate to beg but please? Anybody?


poprelay, rhel, sendmail
