I have postfix server on my linux server. I have configured it to use SSL on port 25. I can send mail to my yahoo account but when I reply to that mail from my yahoo account to my SMTP server the mail is bouncing back and its giving this error message.
Remote host said: 530 5.7.0 Must issue a STARTTLS command first
A few days ago I started having some people tell me that they can't send email to me. Basically, they get a permanent failure. It is very hit or miss though as I'm still getting some mail and not others.
There are a few things that I don't know if they could be contributing factors.
1.) I'm using GMail to check my POP accounts on my webserver.
2.) I have been receiving this message when CPanel runs it's updates at night. The version of perl you are running (v5.8.1) is too old. There are known problems that cannot be worked around with this version of perl. It is HIGHLY recommended that you upgrade to v5.8.5 or later. Any module install failures should be ignored until perl has been upgraded as some modules will not be able to install with this version of perl.
3.) I noticed the WHM interface is updated so maybe something upgraded and broke.
I'm running a Cpanel/Redhat server over at ThePlanet if it matters.
my Exim mail outgoing queue is getting stuck and i cannot receive emails. Under WHM i have 50 odd emails, some 7 days old.
A small dump from /var/log/exim-mainlog is below:

Everything was fine until about 7 days ago, i dont know why the config didnt change but since then its been dropping received emails and queueing on sends.
I have the latest whm/cpanel version installed.
I also have assp deluxe installed.
Here's my problem: I have a client that is having problems with his emails account. When someone sends him a mail from Brinkster.com, a rebound error is received:

This only happens to that specific client. I tried sending a brinkster email to another account on the server, and it works fine. The problem only happens with that specific client..
I have windows server 2008 r2 and plesk 12. I can receive mails but can not send mail. I am receiving mail like this :

Is there a KB (I couldn't find one) - to implement rate limiting for receiving mail on our service nodes?
Just had another customer account compromised (not a very weak password either) - and that meant > 250,000 emails - a LOT of cleanup.
Not only do we need rate limiting, but we also need notification of potential abuses.
So got my dedi the other day. Everything is perfect. However I'm running into some issues.
I have setup some forwarders in cPanel to redirect to my Gmail but unfortunatley I'm not getting them all.
I sent some emails from various address and only received one.
Now I can only think of 3 issues.
1. Something to do with DC/Network.
2. cPanel problem (DC set cpanel up)
3. DNS servers (DC set them)
I have used the mail troubleshooter in WHM and all seems to be fine, it says its sending mail to Gmail so not sure what the problem is.
A client is not receiving some of her e-mails from one account she has on the server.
She receives most but some are getting lost (not being received or bouncing back)
All other e-mail accounts that she has on our server are receiving e-mail fine.
The missing emails are from different domains so it's not a problem with the people sending the emails.
I deleted and reinstalled the account on the server and got her to delete and reinstall the account in Outlook express.
That didnt work.
There are no spam filters in place either on the her server account or in her e-mail client and we are not using any RBLs to block email.
The missing emails are not in the mail queue either.
Hotmail not receiving any emails from my server nevertheless log files is ok no problem and messages sent every thing is ok recently i contacted with my server's provider to make a ptr record at dns to fix hotmail problem and i shoked when i notice that they put a wronge ip
My Q: is that ptr record is important and it could be the reason for making hotmail rejecting my emails
i recently changed host and after i changed host, i am unable to send emails to hotmail from my mail server. Gmail and yahoo are fine.
The error message from Hotmail:
SMTP error from remote mail server after MAIL FROM:<webmaster@joinmo.com> SIZE=3494:
host mx3.hotmail.com [65.54.244.200]: 550 Your e-mail was rejected for policy reasons on this gateway. Reasons for rejection may be related to content with spam-like characteristics or IP/domain reputation problems. If you are not an e-mail/network admin please contact your E-mail/Internet Service Provider for help. For e-mail delivery information, please go to [url]
I also ran a dnsreport and heres the result

I have contacted microsoft but really not sure when they will give me a reply .. meanwhile, if there is any solution to my problem, it would be greatly appreciated.
I moved to a new server today but I think there's one configuration setting causing some problems.
I'm receiving spam in my own mailbox, sent to other people's accounts. My own mailbox is the mailbox to which root and nobody and cpanel addresses are forwarded to. The target email of the spam mails don't exist, so the spam ends up in MY inbox. Any idea what's causing this? Maybe the accounts are not configured to use ":fail:" as catchall address? Though cPanel is configured to use that value as default.
My next question is: How can I change the catchall address of ALL my accounts and set them to ":fail:"? Is there a script I could use?
Anyone know how to fix this? I put it as plain as possible. I've reinstalled qmail once to see if I can get it to send/receive but it is still not working. I made sure the port is not blocked either.
