Embedded devices like this one tend to have outdated versions of SSL libraries, that have trouble communicating with more modern implementations. Does the iDRAC retry to send the mail unencrypted when it gets the TLS connection failure? Can you turn off using TLS on the iDRAC side, to send the mail unencrypted? You can also try to use smtpd_discard_ehlo_keyword_address_maps, to not advertise STARTTLS to this particular client IP address. This should cause the mail to be sent unencrypted. -- Regards, Jaroslaw Rafa r...@rafa.eu.org -- "In a million years, when kids go to school, they're gonna know: once there was a Hushpuppy, and she lived with her daddy in the Bathtub." _______________________________________________ Postfix-users mailing list -- postfix-users@postfix.org To unsubscribe send an email to postfix-users-le...@postfix.org
