Encrypted ASMTP
by Odhiambo Washington 26 Jul '21

26 Jul '21

Hello guys :-) 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? -- 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

Anyone running Exim-4.94?
by Odhiambo Washington 01 Nov '20

Hola, If running exim-4.94, did you all fix this issue silently without discussing it here on the list, or did I miss the discussion? 2020-10-19 07:13:11 1kUMXc-0005pC-OR Tainted filename for search: '/var/spool/exim/db/greylist.db' Anyway, just to say that I Googled and found something that I believe works for exim-4.94: Old: accept condition = ${lookup sqlite {GREYDB SELECT host from resenders \ WHERE helo='${quote_sqlite:$sender_helo_name}' \ AND host='$sender_host_address';} {1}} New: accept condition = ${lookup sqlite,file=GREYDB {SELECT host from resenders \ WHERE helo='${quote_sqlite:$sender_helo_name}' \ AND host='$sender_host_address';} {1}} As discussed here: https://bugzilla.redhat.com/show_bug.cgi?id=1848283 Adiós. -- Best regards, Odhiambo WASHINGTON, Nairobi,KE +254 7 3200 0004/+254 7 2274 3223 "Oh, the cruft.", grep ^[^#] :-)

exim4u not removing mailbox from file system
by Dan Egli 09 Sep '20

09 Sep '20

This is a problem I just encountered. Any time you delete a user from within Exim4u, their mailbox remains on the file system. Plus, if you later add a new user with the same username and domain, they inherit all the previous user's mailbox information, including messages and folders. Is there a way that this could be remedied? It's a pain in the A** for the site admin to have to go in and remove old mailboxes manually after the domain admin deletes the account. Thanks! --- Dan

Relay Errors
by Dan Egli 29 Aug '20

29 Aug '20

I had someone help me get Exim4u installed, and now things mostly look great, except for one problem. I can't send to any other domain unless the message originates on localhost. I have Thunderbird configured to send/receive on this gmail account and my personal server account I'm trying to get working. But when I try to send from my personal server to my gmail I get an error that says relay not permitted. At first I was getting a totally different error saying there was an error, about the dmarc_enable_forensic control having an error, but I was able to comment that part of the ACL out. So what am I doing wrong? Any ideas? I've attached the exim4.conf to this message. Thanks!

What did I do wrong?
by Dan Egli 24 Aug '20

24 Aug '20

I thought I followed the setup exactly, but something must be wrong because my exim4u login page is not only VERY ugly but actually shows some PHP to the user. I've looked and can't figure it out. I need some help please. An example of what it looks like is attached. Thanks!

Hi everyone, exim4u works very well. I have exim4u 3.1.0 on ubuntu 16.04. I have a group with many members, i want add a member with different address from my domain but group accept only local mail address. I create a local address that forward to different domain and add this to the group but with forward the destination mail system doesn't accept any messages cause spf mismatch. Then i change mail address to alias and in this way the destination receive mails but i can't add alias in a group. Have an idea? Can i add a row in group_contents table? Luca

MySQL issue with blocklists
by Odhiambo Washington 26 Mar '19

26 Mar '19

I am using MySQL-8.x I realized that some lookups on the blocklists table were stopping mails from being delivered. MYSQL: query failed: Illegal mix of collations (utf8_general_ci,IMPLICIT) and (utf8mb4_0900_ai_ci,COERCIBLE) for operation '=' So I had to comment out all blocklists lookups (my people don't even create custom ones though) pending advise from here. Anyone dealt with this issue before, or it's only me on MySQL-8.x?? TIA -- Best regards, Odhiambo WASHINGTON, Nairobi,KE +254 7 3200 0004/+254 7 2274 3223 "Oh, the cruft.", grep ^[^#] :-)
