Mohon bantuan dan solusinya terkait transkrip dibawah ini :
Log SMTP-(in) 1 :

can't be resolved
Mail ditolak karena dikirim melalui server yang identitas host nya tidak
terdaftar di internet.
Sudah dibuatkan pengecualian dan diupdate ke

Wed 2025-03-05 13:52:06.192: 05: [11936216] Connection closed
Sender memutus koneksi, kemungkinan karena koneksinya lambat atau
kehabisan resources.
Dalam kondisi seperti ini sender akan retry to send, ditunggu saja.
BTW. Kenapa server mail.swadayagraha.com tidak membatasi message size
(SMTP size)?
Apa karena sudah pakai bandwidth mendekati 10 Gbps seperti milik
IIX/OpenIXP :-)
SMTP size limit itu perlu diaktifkan untuk menghindari email bombs yang
akan menghabiskan kanal bandwidth.

Refuse messages larger than [xx] KB (0=no limit)
Setting a value here will prevent MDaemon from accepting or processing
mail that exceeds a certain fixed size. When this option is enabled
MDaemon will attempt to use the ESMTP SIZE command specified in
RFC-1870. If the sending agent supports this SMTP extension then MDaemon
will determine the message size prior to its actual delivery and will
refuse the message immediately. If the sending agent does not support
this SMTP extension then MDaemon will have to begin acceptance of the
message, track its size periodically during transfer, and finally refuse
to deliver the message once the transaction has completed. Use "0" in
this option if you do not wish to set a size limit.

Mohon tidak kirim private mail (atau cc:) untuk masalah MDaemon.
Making the complex clear always helps people work smarter. It's a lot of
easier to figure out what's important and ignore what isn't.
