 |
|
On rare occasion I get corrupt inboxes with some users....the 1st line of text is always this :
^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@
I am running sendmail with dovecot in mbox format. I can manually repair by remove the 1st few lines up to the 1st "From:" but I was wondering if there is a way to auto fix or stop them getting corrupt ? |

It is very hard to tell.
Could you give more specific, even pedantic, information about how mail is handled, mangled and read on your system?

Well I do have a few milters....like clamav, spamassassin & a couple of others. Do you think I should disable all of these ?
Problem is it happens so infrequently it is going to be hard to tell if this fixes the problem. |

The ^@^@^@^@^@^ lines hint to it that the mailboxes aren't created in 'standard' old-style mbox format but in mbx. Make sure all the programs dealing with mail are configured to use the same format.
There are several, mbox, mboxo, mbx, mix, maildir...
Also, a tool called mailutil can be used to convert between them.

That is hard to answer. If all your software can handle it why not.
Personally I use maildir for MTA delivery (qmail) and mbx as a final MUA format (alpine) because for me it makes incremental backups easier (as it's a single file).
