I am sick of this gmail spam. Does anyone know a solution where I can do something like this: 1. received email from adcpni444 at gmail.com 2. system recognizes this email address has been 'whitelisted', continue with 7. 3. system recognizes as this email never been seen before 4. auto reply with something like (maybe with a wait time of x hours): Your message did not receive the

Hi Folks, I have a couple of questions which I hope that you will be able to assist with, first some background. I run a few sendmail servers that run MailScanner/Spamassassin/sendmail (current versions) on Centos 5.4 and Centos 4.8 These boxes accept mail for a large number of domains (6000+) scan the mail removing spam and then forward the ham to another server for delivery. I am attempting to

Hello everyone, I'm setting up a fetchmail command to run every five minutes so I can get email from another POP3 account. The fetchmail package was installed via yum. I can execute the command manually on the command line. But I'm having trouble when it's run from cron. I have noticed that commands run via cron and execute via /bin/sh, so I tried to run the fetchmail command

I know it is not dovecot who should fix this. But anyone using dovecot is using an MTA, and receiving spam ;) I know how to look at email headers.

Hello Mike, Yes, I am using a static IP address, but in theory, you could use a dynamic one. Nothing technically would prevent email exchanges between two boxes, as long as the SPF records are up to date and the DKIM is properly setup. Unfortunately, some ISPs are simply blacklisting full range of private IP addresses just because they are not officials / commercials. Kind regards, Andr? On

I've received a bunch of these blackberry backscatter messages over the past week and have been unable to determine which list user is the cause of this. Whoever is forwarding your email to the blackberry address below, please fix the situation. It's becoming really annoying receiving these backscatter bounces that give no clue as to what the nature of the problem is. Thanks. Your

Hello, Thanks to some nice people on here and other forums I have pretty much finalized my whole mail system on centos 6.x. With all the checks, greylisting, dev/null of any 8+ spam level SA, I still get a few mails. It seems like everytime I enable a new protectant, the mail stops spamming for a few hours...then the spammers decide I am worthy of using better methods against me..and more

I have dovecot postfix setup on my home server as well. I use a virtual server in the cloud as my mx record and mail relay and have my home record on dynamic dns. It's really effective.

Which part? Hosting the email server at home or the relay in the cloud? On Dec 10, 2017 14:53, "Fabian A.

Out of curiosity would it be possible to configure dovecot in such a way that if a message had been accepted by postfix because it couldn't check quota the message was delivered anyway, despite being over quota? I'd much rather that then risk backscatter. (I used to have quotas, but with the size of disks I've found it easier to simply have a "clue bat?approach and a reasonable

I am sorry if this is an FAQ, but there doesn't seem to be searchable archives, and the supported manufacturer's list doesn't include "surge master". Google was also not much help. I have just put a Linux box and the customer has a "surge max " UPS. Anyone any ideas what protocol it uses? There is a Green serial cable. The manufacturers web site is here:

I'm using Dovecot LDA with Exim. I'm also using Dictionary Quotas in a MySQL database. I want to avoid backscatter completely, so I set "quota_full_tempfail = yes" and handle quota checking in the Exim RCPT ACL during the SMTP session. The problem lies in the case where a user's account is nearly full. Smaller messages will continue to come through, but a larger message
