hi，
i am in warm-up sending process , i notice my application log:
2024/03/26 04:07:16 [error] [application] Cannot find a valid server to send the campaign email, aborting until a delivery server is available! Campaign UID: ql5843syx2d19
but i can see campaigns can still work , /var/log/maillog is still sending email process.
i read the post:

Cannot find a valid server to send the campaign email, aborting until a delivery server is available! | MailWizz Email Marketing Documentation

Cannot find a valid server to send the campaign email, aborting until a delivery server is available!

www.mailwizz.com

but none of them fit my situation
my php version 8.1.2, and delivery server is smtp server created by myself

i am in warm-up sending process

Cannot find a valid server

Warmup plans fo have limits and when they are reached, MailWizz will not use the delivery server for sending until those limits are removed, be it in the next minute, hour, day, month. So MailWizz will resume sending using this server.

but i can see campaigns can still work , /var/log/maillog is still sending email process.

The mail server can queue your emails and you can see activity for days after you stop pushing in the queue. Or you might as well have another campaign/delivery server being used.

Indeed, the only delivery server is occupied by warm-up.
So, as long as add an available delivery server, it won't get an error, right?

That's correct yes.
