I have a seperate mail hub (sendmail 8.12.1) and Cyrus imap server (2.0.16 on Solaris 2.7).
I use lmtp to transfer the mail between them. It seems to work fine for awhile, then I get I/O errors from sendmail, even though I can connect to lmtp on the cyrus server and everything looks OK. After a few minutes it starts working again. >sendmail -q -v Running /var/spool/mqueue/fAEImm4o005332 (sequence 14 of 59) I/O error >From the syslog: Nov 14 13:50:14 mailmachine.gatech.edu sendmail[5667]: [ID 801593 mail.info] fAEIoB4o005650: to=<[EMAIL PROTECTED]>, delay=00:00:02, xdelay=00:00:00, mailer=lmtp, pri=30884, relay=imapmachine.gatech.edu., dsn=4.4.2, stat=I/O error from the sendmail.cf: Mlmtp, P=[IPC], F=sDFMnqAw@/:|SmXz, E=\r\n, S=ENVFroml, R=EnvToL/HdrToL, T=DNS/RFC822/X-Unix, A=TCP $h 2003 Has anyone seen this before?
