I also tried to turn off personal firewall and SAV off, but on the 2 PCs that I could not send email before, I still can't do it. On the 2 PCs that I can send email out, it doesn't matter whether personal firewall and/or SAV is on or off, I can always send mails out. When I try to send emails out on the "failed" PCs, the maillog shows: Sep 22 15:01:54 rust sendmail[18406]: k8MK1stJ018406: [128.252.85.77] did not issue MAIL/EXPN/VRFY/ETRN during connection to MSA Sep 22 15:01:54 rust sendmail[18408]: k8MK1sHQ018408: [128.252.85.77] did not issue MAIL/EXPN/VRFY/ETRN during connection to MSA Sep 22 15:02:02 rust dovecot: imap-login: Login: user=<msnet>, method=PLAIN, rip=::ffff:128.252.85.77, lip=::ffff:128.252.85.35, TLS Sep 22 15:02:02 rust dovecot: imap-login: Login: user=<msnet>, method=PLAIN, rip=::ffff:128.252.85.77, lip=::ffff:128.252.85.35, TLS Sep 22 15:02:02 rust dovecot: imap(msnet): mbox sync: UID inserted in the middle of mailbox /home/msnet/mail/Sent (372 > 11, seq=5, idx_msgs=9) Sep 22 15:03:13 rust dovecot: imap-login: Login: user=<msnet>, method=PLAIN, rip=::ffff:128.252.85.77, lip=::ffff:128.252.85.35, TLS Sep 22 15:03:13 rust dovecot: imap(msnet): mbox sync: UID inserted in the middle of mailbox /home/msnet/mail/Sent (378 > 11, seq=5, idx_msgs=9) Sep 22 15:03:23 rust dovecot: imap(msnet): mbox sync: UID inserted in the middle of mailbox /home/msnet/mail/Sent (384 > 11, seq=5, idx_msgs=9) I also, tried on my FC5 system, the same situation. I just could not figure it out why. Thanks! Hongwei
