[Dovecot] antispam plugin claims "antispam signature not found"
by Jakob Curdes 09 Nov '08

09 Nov '08

Hi, I am trying to setup the antispam plugin using the direct dspam backend. I have set antispam_signature = X-DSPAM-Signature in dovecot.conf and in all mails I have signature lines like X-DSPAM-Signature: 1,49084a24139132188715614 but still, if I try to move a mail into the spam folder, i get the IMAP error message "antispam signature not found". I thought it might have to do with permissions and made sure that the user running dovecot is able to execute the dspam binary. I also tried to enable debug logging to syslog (via the .config file in the make process) but I do not see any debug messages showing up; where should these go? to the mail facility? Perhaps somebody who has a working setup can shed some light on this? Yours, JC

[Dovecot] Renames across namespaces
by Ben Winslow 08 Nov '08

08 Nov '08

Will Dovecot ever support renames across namespaces? I'm attempting to support mailboxes under "INBOX" for compatibility with Courier, which I'm trying to replace, while also supporting mailboxes with no prefix. I don't want to confuse new users (who aren't already subscribed to their mailboxes with the INBOX prefix) by listing the entire tree twice (parented at the root and at INBOX.) This configuration seems to provide what I want: mail_location: maildir:~/mail namespace: type: private separator: . prefix: INBOX. inbox: yes hidden: yes namespace: type: private separator: . list: yes subscriptions: yes ...except that, when a legacy user tries to delete a mailbox under INBOX, Thunderbird (at least) renames the mailbox to make it a child of Trash at the root, e.g.: tag123 RENAME "INBOX.test" "Trash.test" tag123 NO Can't rename mailbox to another storage type. I was a little surprised that it didn't work at first, since they're both using the same (default) mail_location, but I see why it doesn't work after looking at the code. Is there any chance cross-namespace (and even cross-storage _type_) wouldn't eventually be supported? (I guess that the big problem is making cross-type renames appear atomic to clients.) Is there a better way to do what I'm trying to do? -- Ben Winslow <rain(a)bluecherry.net>

[Dovecot] Fetch order
by Warren Baker 07 Nov '08

07 Nov '08

Hi all, Is there a function to modify the fetch order of messages? We have just migrated from Courier to Dovecot and I notice that there is a slight difference in the way messages are fetched in Dovecot compared to Courier. Both Courier and Dovecot sort the mailbox correctly (UID SORT (REVERSE ARRIVAL) UTF-8 ALL), for example: [ 13:22:02.790 ]50800314 UID SORT (REVERSE ARRIVAL) UTF-8 ALL * SORT 195 194 193 192 191 190 189 188 187 186 185 184 183 182 181 180 179 178 177 176 175 174 173 172 171 170 169 168 167 166 165 164 163 162 161 160 159 158 157 156 155 154 153 152 151 150 149 148 147 146 145 144 143 142 141 140 139 138 137 136 135 134 133 132 131 130 129 128 127 126 125 124 123 122 121 120 119 118 117 116 115 114 113 112 111 110 109 108 107 106 105 104 103 102 101 100 99 98 97 96 95 94 93 92 91 90 89 88 87 86 85 84 83 82 81 80 79 78 77 76 75 74 73 72 71 70 69 68 67 66 65 64 63 62 61 60 59 58 57 56 55 54 53 52 51 50 49 48 47 46 45 43 44 42 41 40 39 38 37 36 35 34 33 32 31 30 29 28 27 26 1 4 8 10 15 18 20 25 14 19 2 3 5 9 13 17 21 22 7 11 16 6 12 23 24 50800314 OK Sort completed. But if we fetch the latest 25 messages, Dovecot will fetch the lowest UID in the list first, so from the example above it would fetch UID 171,172,173 and so on. Courier on the other hand would start the fetch on UID 195,194,193 and so on. We have an internal developed webmail application that has been affected by this change, so I am just wondering whether there is a interim fix while we fix our webmail application to cater for this. Thanks, Warren

[Dovecot] index storage usage
by Giorgenes Gelatti 07 Nov '08

07 Nov '08

Hello there, I failed in finding the answer in the wiki so i'm asking it here. In average, how much the dovecot's indexes increase the usage of storage, compared to a standard maildir mailbox? I believe it would be a function of the number of messages instead of the message's size. Is there a known aproximated function for that? Thank you. gpg
