Plesk Automation :: SMTP Rate Limit For Receiving Mail On Service Nodes?

May 5, 2014

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.

Send Mail From Web Form Using 3rd Party SMTP

Apr 1, 2008

I have a CDONTS script which has been sending mail from a client's website form to their address. However, the script has suddenly stopped working. It doesn't error, they just don't receive the mail. I've tried CCing myself in the script and the mail is not getting through. The script itself is tried and tested and syntaxially correct.

I think the problem is because they're using their own exchange server, not the web hosts' mail server. Therefore I would expect that mail sent from the web script wouldn't go through because there is no local mail server to process it.

The problem is that the script hasn't changed, the host say their system hasn't changed, and the client's IT team say their exchange settings haven't changed!

I could set up a CDOSYS script to use their Exchange server to deal with the email, but their IT support won't allow relaying, so I don't think this is possible.

Is connecting to their Exchange box the only option, or should the website host still be able to process the web-script-generated mail despite not being their mail provider? I'm getting a lot of grief here, but it can't be the script that has suddenly broken because nobody has touched it!

Cannot Send Mail Through VPS SMTP Server. The Usual Fixes Didn't Work.

Feb 1, 2007

Over the past week, the SMTP server on my VPS has been hanging whenever I try to send an email from my computer. It'll eventually work again, but now it's been down for the count for about 18 hours. Tech support keeps on recommending minor fxes and issuing standard responses like "try disanbling your firewall" and the like, but nothing works. I have already told them this:

* I know _you_ can probably send POP/SMTP mail through my server. I can't.
* Mozilla Thunderbird will connect and send mail through other
POP/SMTP servers.. Not my server here.
* I can connect to _receive_ email, but I can't send it.
* My ISP (SBC/AT&T ADSL) does not block outgoing mail to port 25 on my account; I had the block removed.
* I've got an exim server running on port 26, too. Doesn't make a difference.
* I tried connecting from another ISP (my work PC). Still can't send mail.
* I tried using IP addresses instead of my domain name. Doesn't work.
* I didn't change any account names, passwords or anything like that.
* I tried other email clients. Can't send mail with them, either.
* The exim queue has very few messages in it. Clearing the queue didn't work.
* I disabled firewalls. Didn't help. Besides, I was able to connect
to other mail servers - just not my VPS here.
* There are no typos in any of the account or general configuration settings in my client. Nothing changed. One day I could send mail, now I'm having problems.

I keep saying this, and keep attaching entried from exim_mainlog with error messages like this PROVING that I can't send mail:

2007-02-01 08:26:00 H=adsl*****
[*****]:1294 I=[*****]:25 incomplete transaction
(connection lost) from for
2007-02-01 08:26:00 unexpected disconnection while reading SMTP
command from adsl*****
[*****]:1294 I=[*****]:25
2007-02-01 08:26:17 SMTP connection from [*****]:1344
I=[*****]:25 (TCP/IP connection count = 1)

2007-02-01 08:29:34 H=adsl*****
[*****]:1344 I=[*****]:25 incomplete transaction
(connection lost) from for
2007-02-01 08:29:34 unexpected disconnection while reading SMTP
command from adsl*****
[*****]:1344 I=[*****]:25

Any ideas? I think tech support at my end has given up; it's been hours since I last heard from them, and that was just to say that they updated everything to the current version, and disable the firewall. (Again!) Didn't work.

So, before I pack my bags and find another VPS host, what should I do? Having outgoing SMTP email is a MUST; not having it is a deal-breaker.

I have followed the instructions here to send Plesk notifications through External SMTP (overuse, new domain creation, etc): URL....Here is the error I see in the panel.log: ERR [panel] Unable to send mail.

Plesk 12.x / Linux :: Do Not Send Email Via SMTP POSTFIX By Php Scripts?

Mar 7, 2015

The problem is, can not send mail via SMTP using popular scripts Opencart, SMF, Osclass. The problem was lapping Plesk 11.5 via 587 port. That was timeout connection or authorization error with the correct settings. Mail may be sent, sometimes not. No longer working than working. At the same time when working with e-mail clients(example, The Bat) work fine. In Plesk 12 same problem. Port 465 - e-mail clients(example, The Bat) work fine. But can not send mail via SMTP using popular scripts Opencart, SMF, Osclass. When using Cpanel with Exim - all work perfect. But the Plesk e-mail with Postfix - constant problems.

Plesk 12.x / Windows :: SMTP Authorization After Migration

Oct 10, 2014

I just finished to migrate my Plesk 10.5 to 12 and everything is great now.

I just have a little problem with SMTP authorization.

This option, if i'm not doing something wrong, is located on Mail Settings and especially in the section "Relay options". I ticked "authorization is required" and "SMTP".

But when I try to check it on my email client, I can send emails with or without the the SMTP authorization option on the email client.

Plesk 11.x / Windows :: Limit Notification Emails To Specific Administrator

May 21, 2014

The 'Additional Administrator Accounts' feature enables a Plesk login to be created for each administrator, so they don't have to share a login, which is good practice.

However, Plesk sends notification emails (e.g. Notification of problem domains) to all the administrators. How can we control who is sent notification emails? In our case, we only want them to go the main admin account.

In the 'Additional Administrator Accounts' form, the 'email' field requires a value. We could set this to a dummy value, but this would probably generate non-delivery emails.
