"recipient verify defer" in exim log

[jbngar]

Hi guys
I have a PHP page that basically has a loop to send a bunch of mail() commands (it's a weekly roster). The problem is that it can take up to a full minute to refresh the page because it waits for all the emails to be sent. When I create a fake roster with just my name and email it goes really quickly, but when it has a lot of different emails it seems to take much longer. In the exim mainlog I have lines that look like this:

2024-02-13 17:25:20 1rZmEK-00000009BgJ-1DnC recipient verify defer (making calloout connection): T=remote_smtp Network is unreachable

which seem to be causing the delays. I've added these extras in my exim.variables.conf.custom:

smtp_accept_queue_per_connection=100
queue_run_max=100
remote_max_parallel=100
disable_ipv6=true
sender_verify=false

and I have added this line to the /usr/local/php81/lib/php.ini:

sendmail_path = /usr/sbin/exim -t -odb

but the recipient verify defer messages remain.

I'm also curious as to why there is the misspelling of 'callout' ('calloout') in the log and where that might be coming from. Any assistance appreciated!

Cheers, John G

I am experiencing this also after a migration and OS change, in just one php program.

Did you find a solution?
