We had a non-client (not on our server) that was getting 550 email rejections when he attempted to email us due to having Sender Verify enabled.
In the past I figured Sender Verify was necessary for fighting spam, amongst other things, but have realized that we may be having more rejections than we know because we never hear about them.
Is there a general best practice in terms of enabling Sender Verify or leaving it off? I've never heard about complaints about rejects from legitimate emails senders, so it doesn't seem to be an issue, but then again, you really never know...

I´m seeing that a lot of servers are rejecting my emails showing this error:
451 - could not verify sender (callout)
Reverse DNS is working fine, and I couldnt see any kind of error on dnsstuff.com.
I´m using EXIM/CPANEL. I tried to send from one cpanel server to another cpanel server and I´m still getting error.

in the last few months Ive got a blacklist warning from spamcop over my server sending bounces and now I find out one of my ips is listed at [url]for doing sender verify and bounces.
I think both of which are ridiculous to blacklist for and I really think most of the anti-spam blacklist people are nothing more then money making rackets. But I guess it seems reasonable to disable these things as it would save some resources.
Anyway what I need to do I guess is only do bounces for local users and disable sender verify. What is the best way to do this with exim?
Every server I have to change is cpanel. Ive googled on this the last 2 days and cant find much info, Mailservers isnt my strong point for sure. Any advice Id appreciate.
UPDATE I found how to disable callouts [url]
Just trying to figure out how to disable bounces now

My mail server receives tons of messages directed towards bogus, non-existant addresses at my domain. When those addresses don't exist, it creates a reply email with the subject "Mail delivery failed: returning message to sender". How do I stop exim from doing this?

I'm an existing customer of Hosting Company X and notice that they have recently launched an offer that is a higher config than what I have right now, at the same price.
When asked about it, I was refused the higher config citing that new offers are not applicable for existing customers. I've been with them for over a year and have been experiencing very good support from them, but this one issue baffles me.
Why are existing customers less important?

I have has this error for awhile. I know it is due to authentication. I have searched many forums and have tried everything they list which is enable smtp authentication in my email client cause it is said that you must authenticate before sending. Have done all that and no matter what when i try to send...sometimes i get this error. I have a bunch of forwarding domains setup and thought that may be the cause. But really I think it is cpanel bug and forget about help from them so I am turning to anyone that may have fixed this issue

For the last 5 days, exim has been retrying to resend email to a recipent every
1 millisecond.
As result, logs are huge, and load is being affected.
So I'd like to know how can I set/configure exim to ingore sending to any
email I'd tell it.
I mean is there any config file I can look into, to set a ignore list, or even
how to have it so that it retries sending every 1 hour, instead of every 1 millisecond.

I use PLESK 11 on one of my servers, and use NS.mydomain & NS1.mydomain, everything works fine, DNS Zones are OK, reverse DNS is OK...
Except on MXTOOLBOX this :
SMTP Valid Hostname > Reverse DNS is not a valid Hostname
SMTP Reverse > DNS Mismatch OK - 195.154.XXX.XXX resolves to mydomain.eu
SMTP Banner Check > OK - Reverse DNS matches SMTP Banner
Tried so many searches on Google, but no response and always 3 same pages from MXTOOLBOX.
I migrated IP of this server in datacenter, because they ask us to do it, so in /etc/hosts for example I found old IP, I changed it, restart network interface, but always the same thing... postfix too (changed IP and restart).

I am having complains from our clients that their mails are always going to spam folders istead of inbox. I decided to have some tests and find out problems which couse the issue and solve them. We have PTR records correctly, Our IPs and domain names are not listed in any blacklists, And I checked "Use DomainKeys" checkbox for all our domains in mail settings.
These were all good and thought that all works well untill I ran a test on [URL].....
I opened a mail file (.MAI) and copied all content (with headers, contents and all) to that site and got a result like;
pts rule name description
---- ---------------------- ---------------------------------------------------
0.0 RCVD_IN_DNSWL_NONE RBL: Sender listed at http://www.dnswl.org/, no trust
[95.108.252.17 listed in list.dnswl.org]
0.0 URIBL_BLOCKED ADMINISTRATOR NOTICE: The query to URIBL was blocked.
[Code] ....
The 3rd line from the last confused me. "Message has a DKIM or DK signature, not necessarily valid" and "DKIM-Signature header exists but is not valid" parts of that report put a question in mind. Does the "Use DomainKeys" checkbox in the Plesk Panel really working? I mean, it creates all the DNS entries and all, but the email message is starting with a line "DomainKey-Status: no signature" and that supports the 2nd line from the last in that report.
The question is, what should I do to make DomainKeys work as it should? I am using the latest 11.5.30 Update #23 of Plesk Panel for Windows on a Windows 2012 Standart server with MainEnable Enterprise Premium. Enterprise version of MainEnable also has DKIM settings available for all the domains in its own panel, but it's disabled because I didn't set anything in there.

please bear w/ me since this is my first time on launching a site online..
My site is being hosted by a free hosting company..
When I tried viewing the source code of my page some of the html tags are not seen like the <html>,<meta>,<head>...
and I can't seem to verify my site on google...
Verification status: NOT VERIFIED
Last attempt Jan 30, 2009: We've detected that your 404 (file not found) error page returns a status of 200 (Success) in the header.
why is this so?
Did the host delete those?
what should i do?

I had a server admin install a new drive in RAID 1 (mirrored drives). I'm not the best linux guy in the world... but is there a way either through linux, WHM/cPanel, etc. to check and verify that the drives are mirroring correctly? I just want to sleep soundly everynight knowing if a drive failed I'd have another drive up and going.
