I'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)
Ubuntu 14.04 with Plesk 12 (10 Domain License).Using this for mail only... multiple domains.Postfix and Dovecot installed. Trying to figure out how to do:
- SASL Auth (Dovecot) - TLS - want above two to be mandatory... no plain text auth and no unencrypted connections.
How do I achieve this with Plesk 12?I have found countless how-to's about doing this with Vanilla (non Plesk) installs with the same server software. However, Postfix main.cf and master.cf both appear to have specific Plesk modificatuons. Same thing for the related Dovecot conf files... also have Plesk specific modifications.
I see no way to enable the desired settings from the Plesk Panel. Can't achieve this within the Panel but also can't modify the conf files without potentially breaking some Plesk-specific functionality? My original hope in purchasing the Plesk license was to make administration of the mail server easier. Unfortunately, I'm struggling to do this now and may have already had this figured out had I not bothered with the Panel.
I have Cpanel, with the "Prevent Nobody from sending emails" in the WHM>Tweak Settings enabled.
I want to force sendmail to use SMPT auth.. so that all mails sent are sent via SMPT and an authenticated POP user. I guess this will help in limiting the "The maximum each domain can send out per hour" setting.
My hosting provider recently (and without any warning) decided to block outgoing connections to port 25. What this means is for any client/domain/email address that has a forwarder setup, the mail will never reach its destination because the connection to the other server always times out. The error logs look like this:
postfix/smtp: connect to ASPMX2.GOOGLEMAIL.COM[188.8.131.52]:25: Connection timed out postfix/smtp: connect to aspmx2.googlemail.com[184.108.40.206]:25: Connection timed out postfix/smtp: connect to aspmx3.googlemail.com[220.127.116.11]:25: Connection timed out postfix/smtp: connect to aspmx4.googlemail.com[18.104.22.168]:25: Connection timed out
I haven't been able to find a way to force relay to 465. Or maybe I shouldn't have relay on at all and do this another way?
I have been trying to determine if I should use Postfix or Exim for our new SMTP gateway. My biggest obstacle is in trying to determine if Postfix can handle the processing as efficiently as Exim.
Basically we have hundreds of domains that will have email going through the gateway. I need to know if Postfix can be configured to perform different actions based on the recipient domain (i.e. block receipt of message or add a header and deliver). It looks like this functionality is handled by using a 3rd party tool like "amavisd".
The problem is that it looks like I have to wait for the DATA to be received before I can send the mail to the filtering tool rather than just waiting until the last RCPT command. It is also unclear as to whether the message will be denied during delivery with a 550 error being returned or whether the message is accepted and a postmaster message is sent. Obviously I would prefer the 550 error.
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 [22.214.171.124] F=<> rejected RCPT <firstname.lastname@example.org>: mail1.data393.net [126.96.36.199] 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.
Anyone 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?
GoDaddy 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?
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.
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.
