Postfix & Courier w/ mailstore on SMB Share(NAS) fetch failure... Hey all. I have successfully followed the howto for Virtual Users And Domains With Postfix, Courier, MySQL And SquirrelMail (CentOS 5.3 x86_64) (but for x86) and I have implemented this system successfully a few times. However I seem to have hit a issue. I have a situation where i have to place the mailstore on a windows NAS. I can sucessfully mounted the share with the correct gid/uid and i can get postfix to delivery mail to it properly however i can't seem to get courier to fetch the mail / display mail in any app (squirrel for example). It shows that there is in new messages eg: [Inbox (2)] but isn't able to display the mail itself. I have also attempted to maually telnet into the imap server and fetch mail and recieved the following error: a fetch 2 body[text] * 2 FETCH () * NO Cannot open message 2 a OK FETCH completed. a fetch 1 body[text] * 1 FETCH () * NO Cannot open message 1 a OK FETCH completed. After trying manually or via an mail app i see the following errors in the /var/log/maillog: Jun 18 09:33:48 mail01 imapd: rename(./new/1245268538.V17I22ed9bM285388.mail01.company.net,S=1034,./cur/1245268538.V17I22ed9bM285388.mail01.company.net,S=1034:2,) failed: No such file or directory fstab: //192.168.0.50/linuxmail /MailStoreAmun cifs username=net/linuxmail,password=Password1,uid=vmail,gid=vmail,auto,iocharset=utf8,file_mode=0700,dir_mode=0700 0 0 I have also tried modes 0777 just to test with no change in results. authmysql(key parts for this issue): MYSQL_UID_FIELD 5000 MYSQL_GID_FIELD 5000 MYSQL_HOME_FIELD "/MailStoreAmun" MYSQL_MAILDIR_FIELD CONCAT(SUBSTRING_INDEX(email,'@',-1),'/',SUBSTRING_INDEX(email,'@',1),'/') After some Googling i have read that it might be use to the MYSQL_MAILDIR_FIELD string, however i don't feel this is the exact issue as all permissions and and paths are all relative to the file system and i can't see how it would be affected just because this is a smb share. Any help would be greatly appreciated. Thanks to all in advance.
