Hi again!

I've make some investigation and found next in

dovecot-1.1.1/src/plugins/quota/quota-storage.c 242 static int quota_save_finish(struct mail_save_context *ctx) 243 { 244 struct quota_transaction_context *qt = QUOTA_CONTEXT(ctx->transaction); 245 struct quota_mailbox *qbox = QUOTA_CONTEXT(ctx->transaction->box); 246 247 if (qbox->module_ctx.super.save_finish(ctx) < 0) 248 return -1; 249 250 qbox->save_hack = TRUE; 251 return quota_check(ctx->transaction, ctx->dest_mail != NULL ? 252 ctx->dest_mail : qt->tmp_mail); 253 }

and in src/dovecot-antispam/antispam-storage-1.1.c

169 static int antispam_save_finish(struct mail_save_context *ctx)
170 {
171         struct antispam_mailbox *asbox =
172                 ANTISPAM_CONTEXT(ctx->transaction->box);
173         struct antispam_internal_context *ast =
174                 ANTISPAM_CONTEXT(ctx->transaction);
175         struct mail *dest_mail;
176         int ret;
177
178         if (asbox->module_ctx.super.save_finish(ctx) < 0)
179                 return -1;
180
181         dest_mail = ctx->dest_mail ? : ast->mail;
182
183         asbox->save_hack = TRUE;
184
185         ret = 0;
186
187         switch (asbox->movetype) {
188         case MMT_UNINTERESTING:
189                 break;
190         case MMT_APPEND:

PS: I've tried to recompile dovecot and plugin with gcc43 instead of gcc2.95 and with -O0 optimizations - same error in a same place. As I understood segfault appears when sent message moving in sent folder or when draft message appears in draft. I think it occurs when both plugins trying to save same message

Hello!

I have port-built dovecot-1.1.1 on freebsd 6.3 i386 box.

There is signal 11 on imap child occurs every time when i'm trying to

send

email. In fact, email is sending to MTA correctly, but when message moving to Sent folder segmentation error appears.

I built dovecot and antispam plugin with -g3 -O0 -pipe
