新裝的sendmail老是發送不了郵件
新手第一次安裝sendmail,裝完后發現無法發送郵件,具體情況如下:
系統環境:linux4.0 +sendmail+Cyrus-imapd
操作步驟
1.安裝時選擇sendmail組件(選擇sendmail所有組件) 將sendmail 和cyrus-imapd服務打勾,(自啟)
2.默認情況下本地可以收發如下:
# echo "hello tdh " |mail -v -s hello tdh@mailserver
tdh@mailserver... Connecting to via relay...

問題一.用foxmail收郵件總是提示如下:
-errinvalid login
重新輸入口令嗎? 重複輸入口令提示.
問題二.當我修改了sendmail.mc后,在本機接收都有問題了
#vi sendmail.mc
修改這一行DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA')dnl
將addr改為:addr=192.168.1.2
#m4 sendmail.mc > sendmail.cf
#vi access
添加192.168.1.2 relay
#makemap hash access.db <access
#vi local-host-names
添加一行mailserver.gzzy.com
#service sendmail restart
#echo "hello tdh " |mail -v -s hello tdh@mailserver
tdh@mailserver... Connecting to via relay...
tdh@mailserver... Deferred: Connection refused by

修改這一行DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA')dnl
將addr改為:addr=192.168.1.2
==> 改成 0.0.0.0
《解決方案》
謝謝abel,修改為0.0.0.0后.本地可以正常收發了
# echo "hello tdh " |mail -v -s hello tdh@mailserver
tdh@mailserver... Connecting to via relay...

用foxmail收郵件時報錯如下:
#tail -f /var/log/maillog
nov 30 10:46:01 mailserver pop3: accepted connection
Nov 30 10:46:01 mailserver pop3: badlogin: dos plaintext tdh SASL(-1): generic failure: checkpass failed
Nov 30 10:46:01 mailserver master: about to exec /usr/lib/cyrus-imapd/pop3d
Nov 30 10:46:01 mailserver pop3: executed
Nov 30 10:46:09 mailserver pop3: accepted connection
Nov 30 10:46:09 mailserver master: about to exec /usr/lib/cyrus-imapd/pop3d
Nov 30 10:46:09 mailserver master: process 4075 exited, status 0
Nov 30 10:46:09 mailserver pop3: executed
Nov 30 10:46:13 mailserver pop3: badlogin: dos plaintext tdh SASL(-1): generic failure: checkpass failed
Nov 30 10:46:18 mailserver master: process 4076 exited, status 0
這裡是不是報sasl出錯,修改為以下兩行,去除了行頭的dnl,還是報同樣的錯.#vi sendmail.mc
dnl TRUST_AUTH_MECH(`EXTERNAL DIGEST-MD5 CRAM-MD5 LOGIN PLAIN')dnl
dnl define(`confAUTH_MECHANISMS', `EXTERNAL GSSAPI DIGEST-MD5 CRAM-MD5 LOGIN PLAIN')dnl
看來還要abel幫一下忙,謝謝!
《解決方案》
你自己先把 sasl (/usr/lib/sasl2/Sendmail.Conf ..) 之類的設定研究清楚,
多 google , 不要冀望別人幫你解決問題
《解決方案》
# more /usr/lib/sasl/smtpd.conf
pwcheck_method: saslauthd
saslauthd_version: 2
這裡要不要改,書上寫這裡是跟sendmail認證相關的設置
我的cyrus-imapd版本如下:
# rpm -qa |grep sasl
cyrus-sasl-md5-2.1.19-5.EL4
cyrus-sasl-2.1.19-5.EL4
cyrus-sasl-plain-2.1.19-5.EL4
《解決方案》
你有同樣的問題我認為同一個 threat 中處理就好了
1. 250-AUTH DIGEST-MD5 CRAM-MD5 <==這裡有錯,最重要的是 LOGIN PLAIN , 但你沒有
2. saslauthd 有沒有啟動,正不正常, -a 參數最好用 pam , 而不用 shadow
