SMTP Relay Service ...
Oct 9, 2009I'm searching for a smtp service that lets me send email from several different emails (domains), lets me connect to non standard port numbers, and which is not banned/do not accept spam.

SMTP Relay Service
Jun 17, 2007Anyone know of a good place to do SMTP relaying through?
We have legitimate clean email that we need to send for my site that gets filtered as junk mail for the major free email services (Hotmail, Yahoo mail, AOL mail, etc.). Unfortunatley it is legitimate email that needs to get through to the end user to register their account.
Right now we use the free 250 smtp relays per day that come with our free GoDaddy hosting account but we are quickly approaching the need to send more than 250 a day and GoDaddy charges a healthy amount for more than 250 a day.
Anyone know of a good economical SMTP relay service?
SMTP Relay Attack!
Jun 27, 2008I have a cPanel server with CSF installed.
Today I face a problem having SMTP Relay attack
I Enabled SMTP Tweak inside WHM and it prevent the relays
But I am still seeing a huge attack inside my exim_mainlog through one of the domain hosting in the server.
I Delete the domain DNS zone, Change the domain name server, it still doesn't stop the attack. How do I go with this? Need help for those experienced in this...
H=mail1.data393.net [208.42.234.80] F=<> rejected RCPT <305stevengan@techobceat.com>: mail1.data393.net [208.42.234.80] is currently not permitted to relay through this server. Perhaps you have not logged into the pop/imap server in the last 30 minutes or do not have SMTP Authentication turned on in your email client.
SMTP Auth From A Relay: How Do I Get Around This
Jul 17, 2008I'd like to describe an issue and see if this sounds familiar to anyone, or if there is a solution that I have not thought of yet.
CAUSE: My ISP (yeah, it's comcast) began blocking port 25 inbound so my personal mail server was no longer receiving mail.
RESOLUTION: I worked through a new DNS re-router to change the port that would now receive mail: from port 25 to port 587. It took me a while to get the routes pointed correctly, but I finally got the messages to route, get through my firewall, and hit the mail server.
NEW PROBLEM: After some IP and DNS routing issues, I finally got things to work, the email that gets sent finally arrives at my mail server. However, the mail server (Alt-N MDaemon) now requires AUTH from the incoming DNS re-direct.
BIG QUESTION: How do I configure MDaemon mail server (or any other mail server, for that matter) to accept the mail from the new re-route server? Mail now re-directed to the new port ALWAYS comes from that route (mx-routes01.editdns.net). Where in the configuration settings of MDaemon do I set it up? I've tried including the host name and the IP address into every WhiteList list I can find, added it to the trusted host name list and everything. I'm at a loss, since it's impossilbe to configure the re-route server to provide AUTH credentials to my mail server. MDaemon now replys to every mail reuqest with : 530
Authentication required (in reply to MAIL FROM command)
Reached SMTP Relay Limit
Jun 11, 2008GoDaddy says: "You have reached your current SMTP relay limit of 1000 per day on the following hosting account" But they assigned a limit of 1,000 -- and i don't use SMTP relay at all. I have set up my active email accounts to use Google SMTP. When I tell GoDaddy about this, they tell me it is my responsibility. So what do i do?

How To Stop SMTP Relay Attack
Mar 24, 2009Server - Windows 2003, IIS, Windows Mail
I am undergoing heavy SMTP attack, if i accept all connections in RELAY setting of SMTP
If i grant access only to Server IP, then attack stops, but all emails send, start bouncing back to me, as relay failed.
How To Change Smtp Relay Ip For Exim

View 6 Replies View RelatedAntivirus Solution For Smtp Relay Server
Mar 31, 2008I have a dedicated windows 2003 server that acts as an smtp relay (legit purposes, not open).
There are large amounts of mail relayed through the server and I would like to install some 3rd party software that can scan the messages/attachments for viruses.
Ideally, if one exists it strips it from the message and notifies the recipient and/or sender of the problem.
any ideas on where to start?
Postfix SMTP Auth (Relay) Problem
Apr 2, 2009I've been trying to set up Postfix to send email for the past few days. I've managed to get it to ask for a username and password, in order to try and send mail to an external domain
I can receive email fine on the server, but I can't send email out
Here is my main.cf file
Code:
command_directory = /usr/sbin
daemon_directory = /usr/lib/postfix
data_directory = /var/lib/postfix
unknown_local_recipient_reject_code = 550
mynetworks = 127.0.0.0/8 192.168.3.0/24
smtpd_recipient_restrictions = permit_mynetworks permit_inet_interfaces permit_sasl_authenticated reject_unauth_destination
mynetworks_style = class
smtpd_sasl_auth_enable = yes
allow_untrusted_routing = yes
relay_domains =
smtpd_client_restrictions = permit_mynetworks permit_inet_interfaces
smtpd_sasl_application_name = smtpd
smtpd_sasl_local_domain = $mydomain
smtp_sasl_mechanism_filter = !plain, static:rest
broken_sasl_auth_clients = yes
smtp_sasl_mechanism_filter = login
myorigin = literatifoundation.org
mydomain = literatifoundation.org
myhostname = literatifoundation.org
mydestination = $myhostname, localhost.$mydomain, $mydomain
When I try to login to send the email, it doesn't accept the password.
Plesk 12.x / Linux :: External SMTP Relay Not Sending Email From Panel
Apr 8, 2015I have Plesk 12 on CentOS 7. I have only MSMTP installed not Postfix or Qmail. No matter what settings I use in the external SMTP settings the mail is never sent and I cannot find any error logs.
I have tried gmail smtp, sendgrid smtp and another smtp server that I own.
This is not a firewall issue as far as I can tell since if I install postfix it just works. Also any Wordpress or Joomla installs that use SMTP settings with gmail or sendgrid work just fine.
Screenshot for information only. I used accurate usernames, passwords, etc.

Quick update. I tried the recommended CentOS 7 with the same result. Can installing Plesk 12 without a mail server and using the msmtp relay option actually works?Click to expand...
Plesk 12.x / Linux :: Postfix Smtp Suddenly Started Issuing Relay Access Denied On All Recipients
Jul 10, 2015After setting up a new server on Plesk12, I successfully ran some test mail outs using phpmailer using the SMTP server on this machine
However, there was an issue in creating new local mail accounts in plesk with an error message each time.
Investigating this issue led me to a solution that I should run mail_restore from the Plesk scripts
This cured the problem of setting up new local accounts but outgoing SMTP mail is always failing with 'relay access denied'.
Backup SMTP Or Something Similar Service
Feb 20, 2007i found the service for backup of SMTP:
If your mail server or network goes down, our backup SMTP can receive and store your incoming e-mail for up to 30 days. E-mail and ecommerce orders will keep coming, giving your IT staff time to repair the problem. Our standard service reattempts delivery every 15 minutes until your mail server is back online.
Seems that is good decision if you want to provide quality services for your cusutmers, but i want to know your opinion regarding this service or similar. did you use services like this , and can you share some experience for this?
Not Able To Send Mail Using SMTP Service On Windows 2003 Server Machine
Jun 17, 2008Am using Windows 2003 server with IIS6.0 and SMTP.I tried to send mail using ASP.net C# code through SMTP service.But my mails are getting queued in C:InetpubmailrootQueue.
What could be the problem??I've done many trouble shooting steps but no luck.I changed the Relay settings.Since I am in a LAN connection, i've tested the relay setting using both the 'localhost'and 'MyDomainIP'but everything in vain.
Plesk 11.x / Linux :: SMTP Service (qmail) Stops Responding On Port 25
May 19, 2015Since 15.05.2015 smtp experiencing problems.
Smtp service (qmail) stops responding on port 25:
# time telnet localhost 25
Trying 127.0.0.1...
quit
quit
Connected to localhost.localdomain (127.0.0.1).
Escape character is '^]'.
quit
quit
Connection closed by foreign host.
real 4m10.629s
user 0m0.000s
sys 0m0.002s
After server restart or sometimes apache stop or ixnetd restart its responding for a some random time, and then again it stops to respond. Plesk panel show it as stopped but qmail itself running in memory, and does other its work, it just stops responding at port 25, or responds with a huge delay.
I've tried change it to postfix, reconfigured with mchk, repaired with repair.sh -r, disabled and uninstalled parallels antivirus, antispam, dnsbl, disabled firewall, disabled smtp lock. Checked apache, dns. Enabled submission port which works when 25 port doesnt, but i need working 25 port.
Nothing solves problem, its just stops responding after some random time. There is no errors on maillog.
I think this problem occured after recent plesk microupdate, because i didn't do anything to server configuration in last months.
This article says it might be dnsbl [URL] .... but it disabled(from plesk panel) on my server, maybe there is way to focefully kill any relation to dnsbl?
Plesk info:
OS Red Hat Enterprise Linux Server 5.9 (Tikanga)
Panel version 11.5.30 Update #50, last updated at May 18, 2015 05:21 PM
The system is up-to-date; last checked at May 17, 2015 10:56 PM
update: xinetd restart is definitely brings smtp alive, but it goes off after random period of time (5min ~ couple hours)
Plesk Automation :: SMTP Rate Limit For Receiving Mail On Service Nodes?
May 5, 2014Is 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.
