My server is running WHM 11.15.0 cPanel 11.18.6-S24739 /
REDHAT Enterprise 4 i686 on standard.
I am using EXIM.
Lately, users on my server have not been able to receive most attachments. E-mails with small attachments, such as an 11,000 byte file, show up just fine. An e-mail from the same person, but with a 560,000 byte attachment will simply never show up, and there is no returned "bounce" message to the sender. It is like the e-mail was never sent.
The odd thing is, e-mails sent to and from e-mail addresses hosted on my server have no trouble sending/receiving large attachments of any size (I have tested up to several megs in size). For example, tom@example.com and joe@another_example.com both have their domains hosted on my server. They can send each other large attachments with no trouble. But, if tom@yahoo.com or tom@gmail.com tries to send a larger attachment to tom@example.com, the e-mail and the attachment never show up.
Things to note:
1) The e-mail accounts are no-where near their storage limits.
2) message_size_limit is not set, so I assume the max attachment limit is the default 50mb.
I have a customer who needs to move her existing hosting to another provider. The one thing she likes about the existing provider, however, is an allowance of Email attachments of 50-75MB in size. Most limit you to 10-20MB. Does anyone know of a hosting provider that would accomodate this?
We are experiencing a very strange problem. This is NOT related to authenticating SMTP, or any antivirus or firewall software. Let me know that it has been tested in several machines and we got our conclusions, and the same did some other technicians.
We own a dedicated server with around 70 domains. We do not resell hosting. We just develop sites and host them there, usually with their emails too.
This first all started with a customer that could not send attachments on his email. He told us that could not send email with attachments. Normal emails worked, but not this.
Of course we helped them configuring the account once and again. In some cases it seemed to work, but then it didn't. We thought it could be related to their ISP, because it happened the same in different shops they own in different locations. This happened to them when sending files (reports) each other (all in the same domain).
The error they were getting was about "Socket Error 10053. 0x800ccc0f". I was able to reproduce this error unchecking the "smtp needs authentication", and also "use the following account", while inserting a username but not password. Anyway, as I stated before, all this has been checked and re-checked. So seems to have no relation with antivirus or authentication error.
In other cases, people has been able to send them the email, and they receive nothing.
Then, after a few days, the sender receives some kind of mail delivery error.
Webmail also does not seem to work for them. They see the page strangely loaded, they say, and then attacing a file and hitting Upload, they get a "page not found", when I can see it perfectly and run it, on my office.
Then another customer called... webmail was also weird, and his own web site was doing strange things. Some images were not loading, but when refreshing, you could see those images loaded, and maybe others not. Something random every refresh. At same time, this customer had problems when sending an email with attachment to another customer that is in our own server.
Today some more customers called... one was very angry because a customer (his customer, not ours) could not send email to him. So mails yes, others not. Guess?. Yeah: attachments.
The other call was about the same... a designer that could not receive attachments (to work), because the other side was getting errors when attaching.
And another customer called because one of their customer could not send attachments.
This customer's customer is a big company (with around 1,000 employes), and their technicians checked their own accounts. They said everything was OK so it had to be something wrong in our customers account.
Of course we work normally, we have no problems, and no other calls received.... web sites are OK, server seems to be OK... I phoned the ISP that maybe was having trouble, I also phoned my hosting provider... but you know "we will check", "yes we are checking it", etc.. for about 4-5 days now.
And I'm really lost.
Does anyone have an idea of what could be happening? Is there any way to "block" attachments to a router/server/connection? This is the only idea that can go on my mind... in that case, how do I check this?
This started happening around 12-15 days ago. At same timeframe, there were a couple of servers hacked in this hosting provider, but I'm not sure if this has something to do with it... today we received an email about "network manteinance" at 7pm.
Any help or clue will be appreciated, as I'm only a web developer, with basic tech knowledge, so not a veteran system admin...

Currently I am on a shared hosting service. My main concerns are to send a newsletter every fortnight which has an attachment of about 3 MB and has to be delivered to 800+ members.
In doing so on a shared hosting plan i receive a memory allocation error as the php.ini has 32 MB and i cannot change it because i am on shared hosting. I am using Joomla and Acajoon component to send the mails; after every 7-8 mails out of 800 members i recive the fatal error of memory allocation and I am looking for a solution to this problem.
My main concerns are of sending 3 MB attachment mails to the members . What kind of hosting should i go for in order to send mails successfully.

Browsers: Chrome Version 31.0.1650.63 m and IE 8
smaller files upload fine, though when reaching the 10MB and above level, after the attachment loads the new message window defaults to the Your Session Has Expired. Please Login Again.
Are there any settings that I am missing, or is this a current bug in this version of Horde?
I just installed WAMPP on Windows Vista 32 machine. I am using Firefox. When I try the localhost, I receive a 404 error. I have no idea what else to check the UAC is off, port 80 is free, I am running Avast as my anti-virus. I am a complete newbie to PHP, Apache, & MySql. I am trying to learn so I can run some PHP scripts for my website.
I didn't do any updates, but received this email from lfd: it could be because of automatic cpanel update ? if yes how to check the last update Date/information

The following list of files have FAILED the md5sum comparison test. This means that the file has been changed in some way. This could be a result of an OS update or application upgrade. If the change is unexpected it should be investigated:
I create an email address at my site:webmaster@mydomain.com.But it can't receive emails.What's the problem?
Delivery to the following recipient failed permanently:
Technical details of permanent failure:
PERM_FAILURE: Google tried to deliver your message, but it was rejected by the recipient domain. We recommend contacting the other email provider for further information about the cause of this error. The error that the other server returned was: 530 530 Relaying not allowed (state 14).
I have a test server from which I can send out emails.. but I am unable to receive emails although I can connect and login to the pop3 server locally (telnet localhost 110)
How can I investigate this issue to find the problem and fix it
PERM_FAILURE: SMTP Error (state 9): 550-wr-out-0506.google.com [64.233.184.239] is currently not permitted to relay 550-through this server. Perhaps you have not logged into the pop/imap server 550-in the last 30 minutes or do not have SMTP Authentication turned on in your 550 email client.
Like so many others I am having the problem in which Hotmail and Yahoo are rejecting emails being sent from my server. I recently changed servers and this is most likely the reason.
While Hotmail hasn't been fixed, they have responded swiftly, usually within 6 hours.
I need to contact Yahoo about it but I can't find any information or forms to fill out. Could you please direct me to the correct URL - their site is a complete maze.

1) On testing sendmail to Internet encounting following problem;
$ telnet localhost 25 Code: Trying 127.0.0.1... Connected to localhost.localdomain. Escape character is '^]'. ehlo xyg.com It hung here after hitting [Enter]
2) All mails sent on yahoo.com/gmail.com to this server returned saying users NOT found. However the respective users including Maildir have been created. Mails sent to them on Intranet w/o problem.
SMTP Server (QMail) is stoped in PLESK >> Server >> Service Managment and I cannot start from there.
my customers cannot send/receive their emails, I contacted with our data center to solve this problem for me and they said because the CalmAV was disabled we have this problem, we start the CalamAV but we have this problem yet!
we can sent mail from server but we don't receive any mail.
some of site at our servers receive many bounce email seems spamers use those domains as a sender or use sendmail php function in some scripts at accounts
I am a reseller with Hostforweb.com and have a minor problem that is turning into a major problem.
A number of email addresses within my clients can't receive server generated activation or verification emails, and therefore, cannot join many professional sites. It seems to be problematic with php generated email. The last two sites that I have tried to join are:
Drupal.org and Joomla.org.
HostforWeb keeps saying that is the fault of the webserver that I am trying to activate membership on. I am getting the royal run around while I am losing paying accounts.
Any body with this problem on HostforWeb.com or any other web host?
Also, I can receive the verification email on other mail addresses - both POP and IMAP.
after turning on the iptables firewall i can't receive emails anymore on a dedicated centos 5.3 server with postfix and dovecot.

I registered a domain and ordered an hosting package in a registrar. But my site was always down. So I ordered a VPS server in another webhosting site and transferred my site data to this VPS hosting.
I changed the nameserver of my domain and made it point to my VPS server IP. Everything is OK but there is some problem with the mail function. I can send e-mail to admin@mydomain.com from other e-mail addresses. But the mainbox admin@mydomain.com can't receive e-mail from other e-mail addresses. Can anyone tell me what the problem is? Do I need to do some settings in WHM or cpanel?
