Forwarding to Gmail no longer works because of SPF

Hello everyone, Hope you are keeping well. I have an issue with email forwarding that I am trying to figure out. Exim-4.97 here, with Exim4U if that matters. I have a setting where emails sent to ALIAS@domain are forwarded to USER1ACCOUNT(a)gmail.com and USER2ACCOUNT(a)gmail.com For domains with strict SPF, this definitely fails as shown below. <CUT> This message was created automatically by mail delivery software. A message that you sent could not be delivered to one or more of its recipients. This is a permanent error. The following address(es) failed: USER1ACCOUNT(a)gmail.com (ultimately generated from COMMON_ADDR@domain) host gmail-smtp-in.l.google.com [142.250.27.26] SMTP error from remote mail server after end of data: 550-5.7.26 The MAIL FROM domain [alexanna.co.ke] has an SPF record with a hard 550-5.7.26 fail policy (-all) but it fails to pass SPF checks with the ip: 550-5.7.26 [41.212.32.14]. To best protect our users from spam and phishing, 550-5.7.26 the message has been blocked. Please visit 550-5.7.26 https://support.google.com/mail/answer/81126#authentication for more 550 5.7.26 information. mm11-20020a170906cc4b00b009c74e4ffa08si671339ejb.279 - gsmtp USER2(a)gmail.com (ultimately generated from COMMON_ADDR@domain) host gmail-smtp-in.l.google.com [142.250.27.26] SMTP error from remote mail server after end of data: 550-5.7.26 The MAIL FROM domain [alexanna.co.ke] has an SPF record with a hard 550-5.7.26 fail policy (-all) but it fails to pass SPF checks with the ip: 550-5.7.26 [41.212.32.14]. To best protect our users from spam and phishing, 550-5.7.26 the message has been blocked.

This case is similar to https://lists.exim.org/lurker/thread/20231106.101434.4a28c7c1.en.html except that I do not use the redirect router. The forwarded email is handled by the remote_smtp transport Has anyone else faced this issue with Gmail and other providers? How do you mitigate this? -- Best regards, Odhiambo WASHINGTON, Nairobi,KE +254 7 3200 0004/+254 7 2274 3223 "Oh, the cruft.", egrep -v '^$|^.*#' ¯\_(ツ)_/¯ :-) [How to ask smart questions: http://www.catb.org/~esr/faqs/smart-questions.html]

Unencrypted and Encrypted ASMTP in parallel - posssible?
by Odhiambo Washington 27 Jul '21

27 Jul '21

I am trying to wrap my head around the following config options: # Port 25 or local is MTA IS_MTA_PORT = or{ \ {eq{$interface_port}{25}} \ {eq{$interface_port}{-1}} \ } # advertise SMTP AUTH on all ports except the inbound MTA one, which of course is 25. # Auth on ports not used for MTA (=> MUAs) auth_advertise_hosts = ${if IS_MTA_PORT {}{*}} So our MuAs are set to use port 587 with ASMTP because we are advertising auth on ports other than 25. However, now I'd like to still use TLS encryption, but only as an option: 1. If the MuA is not set to use TLS/SSL, then do not use it 2. If it is set to use TLS/SSL, then use it. The following line requires TLS encryption for all authenticated connections: auth_advertise_hosts = ${if eq{$tls_cipher}{}{}{*}} How do I combine the two auth_advertise_hosts - one with encryption and one without? Both on ports other than 25 (e.g 587 or 465) Or maybe advertise encrypted ASMTP on 465 and unencrypted on 587? Thanks in advance -- Best regards, Odhiambo WASHINGTON, Nairobi,KE +254 7 3200 0004/+254 7 2274 3223 "Oh, the cruft.", egrep -v '^$|^.*#' :-)

Exim 4u on Freebsd 12 and Php 7.4
by exim4u＠compudoc.za.net 02 Apr '21

02 Apr '21

Hi I am looking for some help. I am trying to get exim4u to work on the following FreeBSD 12 and Php 7.4 Has there been anyone on the group who has managed to do so. I keep on bumping into errors just trying to get the web interface going. This is the one error that is driving me nuts. [Thu Apr 01 14:14:41.402888 2021] [php7:error] [pid 2192] [client 192.168.0.11:52771] PHP Fatal error: Uncaught Error: Undefined class constant 'MYSQL_ATTR_INIT_COMMAND' in /home/hosted/exim4u/public_html/config/variables.php:12\nStack trace:\n#0 /home/hosted/exim4u/public_html/index.php(2): require_once()\n#1 {main}\n thrown in /home/hosted/exim4u/public_html/config/variables.php on line 12 $dboptions = array(PDO::MYSQL_ATTR_INIT_COMMAND => 'SET NAMES UTF8'); I tried various suggestions I have found on the web but no luck. If there is a community member who has Exim4u working with php 7.2 would they mind sharing it with me. I have a perfectly working system on Freebsd 10 and using php 5.6 I have been told by my hosting company I must upgrade my server etc. I am open to all suggestions even changing my os if it comes to that. I really need this to work. Thank you any and all help it will be really appreciated. Kind Regards Godfrey Hamshire
