SENDMAIL - SYSERR(root)

[Ladislav Vyslouzil]

Dobry den.

Mam nasledujici problem s mail serverem.

V logu maillserveru se objevuje chybove hlaseni (sendmail, LINUX RedHat5.2):

May 30 04:58:02 ns sendmail[4641]: EAA04641: collect: premature EOM: Connection
reset by relay1.inext.cz
May 30 04:58:02 ns sendmail[4641]: EAA04641: SYSERR(root): collect: I/O error on
 connection from relay1.inext.cz, from=<XXX na ol.cesnet.cz>: Connection reset by
 relay1.inext.cz
May 30 04:58:02 ns sendmail[4641]: EAA04641: from=<XXX na ol.cesnet.cz>, size=61
519, class=0, pri=0, nrcpts=1, bodytype=8BITMIME, proto=ESMTP, relay=root na relay1
.inext.cz [194.213.32.236]

Objevuje se to jen ve spojeni s uvedenou e-mail adresou, jinak vsecko funguje bez problemu.
Jednim smerem, tj. z naseho serveru na XXX na ol.cesnet.cz to jde v pohode, ale opacnym
smerem ne. Mail se jim vraci s hlaskou: 451, I/O error: Error 0

Nevite nekdo cim by to mohlo byt ?
